API Reference

This reference reflects Leaflet 1.0.0-rc3.

Docs for 0.7 are available here. Docs for 0.6 are available in the source form (see instructions for running docs).

Map

The central class of the API — it is used to create a map on a page and manipulate it.

Usage example

// initialize the map on the "map" div with a given center and zoom
var map = L.map('map', {
    center: [51.505, -0.09],
    zoom: 13
});

Creation

Factory	Description
`L.map(<String> id, <Map options> options?)`	Instantiates a map object given the DOM ID of a `<div>` element and optionally an object literal with `Map options`.
`L.map(<HTMLElement> el, <Map options> options?)`	Instantiates a map object given an instance of a `<div>` HTML element and optionally an object literal with `Map options`.

Options

Option	Type	Default	Description
`preferCanvas`	`Boolean`	`false`	Whether `Path`s should be rendered on a `Canvas` renderer. By default, all `Path`s are rendered in a `SVG` renderer.

Control options

Option	Type	Default	Description
`attributionControl`	`Boolean`	`true`	Whether a attribution control is added to the map by default.
`zoomControl`	`Boolean`	`true`	Whether a zoom control is added to the map by default.

Interaction Options

Option	Type	Default	Description
`closePopupOnClick`	`Boolean`	`true`	Set it to `false` if you don't want popups to close when user clicks the map.
`zoomSnap`	`Number`	`1`	Forces the map's zoom level to always be a multiple of this, particularly right after a `fitBounds()` or a pinch-zoom. By default, the zoom level snaps to the nearest integer; lower values (e.g. `0.5` or `0.1`) allow for greater granularity. A value of `0` means the zoom level will not be snapped after `fitBounds` or a pinch-zoom.
`zoomDelta`	`Number`	`1`	Controls how much the map's zoom level will change after a `zoomIn()`, `zoomOut()`, pressing `+` or `-` on the keyboard, or using the zoom controls. Values smaller than `1` (e.g. `0.5`) allow for greater granularity.
`trackResize`	`Boolean`	`true`	Whether the map automatically handles browser window resize to update itself.
`boxZoom`	`Boolean`	`true`	Whether the map can be zoomed to a rectangular area specified by dragging the mouse while pressing the shift key.
`doubleClickZoom`	`Boolean\|String`	`true`	Whether the map can be zoomed in by double clicking on it and zoomed out by double clicking while holding shift. If passed `'center'`, double-click zoom will zoom to the center of the view regardless of where the mouse was.
`dragging`	`Boolean`	`true`	Whether the map be draggable with mouse/touch or not.

Map State Options

Option	Type	Default	Description
`crs`	`CRS`	`L.CRS.EPSG3857`	The Coordinate Reference System to use. Don't change this if you're not sure what it means.
`center`	`LatLng`	`undefined`	Initial geographic center of the map
`zoom`	`Number`	`undefined`	Initial map zoom level
`minZoom`	`Number`	`undefined`	Minimum zoom level of the map. Overrides any `minZoom` option set on map layers.
`maxZoom`	`Number`	`undefined`	Maximum zoom level of the map. Overrides any `maxZoom` option set on map layers.
`layers`	`Layer[]`	`[]`	Array of layers that will be added to the map initially
`maxBounds`	`LatLngBounds`	`null`	When this option is set, the map restricts the view to the given geographical bounds, bouncing the user back when he tries to pan outside the view. To set the restriction dynamically, use `setMaxBounds` method.
`renderer`	`Renderer`	`*`	The default method for drawing vector layers on the map. `L.SVG` or `L.Canvas` by default depending on browser support.

Animation Options

Option	Type	Default	Description
`fadeAnimation`	`Boolean`	`true`	Whether the tile fade animation is enabled. By default it's enabled in all browsers that support CSS3 Transitions except Android.
`markerZoomAnimation`	`Boolean`	`true`	Whether markers animate their zoom with the zoom animation, if disabled they will disappear for the length of the animation. By default it's enabled in all browsers that support CSS3 Transitions except Android.
`transform3DLimit`	`Number`	`2^23`	Defines the maximum size of a CSS translation transform. The default value should not be changed unless a web browser positions layers in the wrong place after doing a large `panBy`.
`zoomAnimation`	`Boolean`	`true`	Whether the map zoom animation is enabled. By default it's enabled in all browsers that support CSS3 Transitions except Android.
`zoomAnimationThreshold`	`Number`	`4`	Won't animate zoom if the zoom difference exceeds this value.

Panning Inertia Options

Option	Type	Default	Description
`inertia`	`Boolean`	`*`	If enabled, panning of the map will have an inertia effect where the map builds momentum while dragging and continues moving in the same direction for some time. Feels especially nice on touch devices. Enabled by default unless running on old Android devices.
`inertiaDeceleration`	`Number`	`3000`	The rate with which the inertial movement slows down, in pixels/second².
`inertiaMaxSpeed`	`Number`	`Infinity`	Max speed of the inertial movement, in pixels/second.
`easeLinearity`	`Number`	`0.2`
`worldCopyJump`	`Boolean`	`false`	With this option enabled, the map tracks when you pan to another "copy" of the world and seamlessly jumps to the original one so that all overlays like markers and vector layers are still visible.
`maxBoundsViscosity`	`Number`	`0.0`	If `maxBounds` is set, this option will control how solid the bounds are when dragging the map around. The default value of `0.0` allows the user to drag outside the bounds at normal speed, higher values will slow down map dragging outside bounds, and `1.0` makes the bounds fully solid, preventing the user from dragging outside the bounds.

Option	Type	Default	Description
`keyboard`	`Boolean`	`true`	Makes the map focusable and allows users to navigate the map with keyboard arrows and `+`/`-` keys.
`keyboardPanDelta`	`Number`	`80`	Amount of pixels to pan when pressing an arrow key.

Mousewheel options

`wheelPxPerZoomLevel`	`Number`	`60`	How many scroll pixels (as reported by L.DomEvent.getWheelDelta) mean a change of one full zoom level. Smaller values will make wheel-zooming faster (and vice versa).

Touch interaction options

Option	Type	Default	Description
`tap`	`Boolean`	`true`	Enables mobile hacks for supporting instant taps (fixing 200ms click delay on iOS/Android) and touch holds (fired as `contextmenu` events).
`tapTolerance`	`Number`	`15`	The max number of pixels a user can shift his finger during touch for it to be considered a valid tap.
`touchZoom`	`Boolean\|String`	`*`	Whether the map can be zoomed by touch-dragging with two fingers. If passed `'center'`, it will zoom to the center of the view regardless of where the touch events (fingers) were. Enabled for touch-capable web browsers except for old Androids.
`bounceAtZoomLimits`	`Boolean`	`true`	Set it to false if you don't want the map to zoom beyond min/max zoom and then bounce back when pinch-zooming.

Conversion Methods

Method	Returns	Description
`getZoomScale(<Number> toZoom, <Number> fromZoom)`	`Number`	Returns the scale factor to be applied to a map transition from zoom level `fromZoom` to `toZoom`. Used internally to help with zoom animations.

Geolocation methods

Method	Returns	Description
`locate(<Locate options> options?)`	`this`	Tries to locate the user using the Geolocation API, firing a `locationfound` event with location data on success or a `locationerror` event on failure, and optionally sets the map view to the user's location with respect to detection accuracy (or to the world view if geolocation failed). Note that, if your page doesn't use HTTPS, this method will fail in modern browsers (Chrome 50 and newer) See `Locate options` for more details.
`stopLocate()`	`this`	Stops watching location previously initiated by `map.locate({watch: true})` and aborts resetting the map view if map.locate was called with `{setView: true}`.

▶ Methods inherited from Evented

Method	Returns	Description
`on(<String> type, <Function> fn, <Object> context?)`	`this`	Adds a listener function (`fn`) to a particular event type of the object. You can optionally specify the context of the listener (object the this keyword will point to). You can also pass several space-separated types (e.g. `'click dblclick'`).
`on(<Object> eventMap)`	`this`	Adds a set of type/listener pairs, e.g. `{click: onClick, mousemove: onMouseMove}`
`off(<String> type, <Function> fn?, <Object> context?)`	`this`	Removes a previously added listener function. If no function is specified, it will remove all the listeners of that particular event from the object. Note that if you passed a custom context to `on`, you must pass the same context to `off` in order to remove the listener.
`off(<Object> eventMap)`	`this`	Removes a set of type/listener pairs.
`off()`	`this`	Removes all listeners to all events on the object.

`listens(<String> type)`	`Boolean`	Returns `true` if a particular event type has any listeners attached to it.
`once(…)`	`this`	Behaves as `on(…)`, except the listener will only get fired once and then removed.
`addEventParent(<Evented> obj)`	`this`	Adds an event parent - an `Evented` that will receive propagated events
`removeEventParent(<Evented> obj)`	`this`	Removes an event parent, so it will stop receiving propagated events
`addEventListener(…)`	`this`	Alias to `on(…)`
`removeEventListener(…)`	`this`	Alias to `off(…)`

Properties

Interaction handlers

Interaction handlers are properties of a marker instance that allow you to control interaction behavior in runtime, enabling or disabling certain features such as dragging (see Handler methods). Example:

marker.dragging.disable();

Property	Type	Description
`dragging`	`Handler`	Marker dragging handler (by both mouse and touch).

Used to open popups in certain places of the map. Use Map.openPopup to open popups while making sure that only one popup is open at one time (recommended for usability), or use Map.addLayer to open as many as you want.

If you want to just bind a popup to marker click and then open it, it's really easy:

marker.bindPopup(popupContent).openPopup();

Path overlays like polylines also have a bindPopup method. Here's a more complicated way to open a popup on a map:

var popup = L.popup()
    .setLatLng(latlng)
    .setContent('<p>Hello world!<br />This is a nice popup.</p>')
    .openOn(map);

Factory	Description
`L.popup(<Popup options> options?, <Layer> source?)`	Instantiates a `Popup` object given an optional `options` object that describes its appearance and location and an optional `source` object that is used to tag the popup with a reference to the Layer to which it refers.

Option	Type	Default	Description

`minWidth`	`Number`	`50`	Min width of the popup, in pixels.
`maxHeight`	`Number`	`null`	If set, creates a scrollable container of the given height inside a popup if its content exceeds it.
`autoPan`	`Boolean`	`true`	Set it to `false` if you don't want the map to do panning animation to fit the opened popup.
`autoPanPaddingTopLeft`	`Point`	`null`	The margin between the popup and the top left corner of the map view after autopanning was performed.
`autoPanPaddingBottomRight`	`Point`	`null`	The margin between the popup and the bottom right corner of the map view after autopanning was performed.
`autoPanPadding`	`Point`	`Point(5, 5)`	Equivalent of setting both top left and bottom right autopan padding to the same value.
`keepInView`	`Boolean`	`false`	Set it to `true` if you want to prevent users from panning the popup off of the screen while it is open.
`closeButton`	`Boolean`	`true`	Controls the presence of a close button in the popup.
`autoClose`	`Boolean`	`true`	Set it to `false` if you want to override the default behavior of the popup closing when user clicks the map (set globally by the Map's closePopupOnClick option).

▶ Options inherited from DivOverlay

Option	Type	Default	Description
`offset`	`Point`	`Point(0, 7)`	The offset of the popup position. Useful to control the anchor of the popup when opening it on some overlays.
`zoomAnimation`	`Boolean`	`true`	Whether to animate the popup on zoom. Disable it if you have problems with Flash content inside popups.
`className`	`String`	`''`	A custom CSS class name to assign to the popup.

marker.bindTooltip("my tooltip text").openTooltip();

Note about tooltip offset. Leaflet takes two options in consideration for computing tooltip offseting:

the offset Tooltip option: it defaults to [0, 0], and it's specific to one tooltip. Add a positive x offset to move the tooltip to the right, and a positive y offset to move it to the bottom. Negatives will move to the left and top.
the tooltipAnchor Icon option: this will only be considered for Marker. You should adapt this value if you use a custom icon.

Polyline

A class for drawing polyline overlays on a map. Extends Path.

Usage example

// create a red polyline from an array of LatLng points
var latlngs = [
    [-122.68, 45.51],

Polygon

A class for drawing polygon overlays on a map. Extends Polyline. Note that points you pass when creating a polygon shouldn't have an additional last point equal to the first one — it's better to filter out such points.

Usage example

// create a red polygon from an array of LatLng points
var latlngs = [[-111.03, 41],[-111.04, 45],[-104.05, 45],[-104.05, 41]];
var polygon = L.polygon(latlngs, {color: 'red'}).addTo(map);
// zoom the map to the polygon
map.fitBounds(polygon.getBounds());

You can also pass an array of arrays of latlngs, with the first array representing the outer shape and the other arrays representing holes in the outer shape:

var latlngs = [
  [[-111.03, 41],[-111.04, 45],[-104.05, 45],[-104.05, 41]], // outer ring
  [[-108.58,37.29],[-108.58,40.71],[-102.50,40.71],[-102.50,37.29]] // hole
];

Additionally, you can pass a multi-dimensional array to represent a MultiPolygon shape.

var latlngs = [
  [ // first polygon
    [[-111.03, 41],[-111.04, 45],[-104.05, 45],[-104.05, 41]], // outer ring
    [[-108.58,37.29],[-108.58,40.71],[-102.50,40.71],[-102.50,37.29]] // hole
  ],
  [ // second polygon
    [[-109.05, 37],[-109.03, 41],[-102.05, 41],[-102.04, 37],[-109.05, 38]]

SVG

Although SVG is not available on IE7 and IE8, these browsers support VML, and the SVG renderer will fall back to VML in this case. VML was deprecated in 2012, which means VML functionality exists only for backwards compatibility with old versions of Internet Explorer.

Allows vector layers to be displayed with SVG. Inherits Renderer. Due to technical limitations, SVG is not available in all web browsers, notably Android 2.x and 3.x. Although SVG is not available on IE7 and IE8, these browsers support VML (a now deprecated technology), and the SVG renderer will fall back to VML in this case.

Usage example

Use SVG by default for all paths in the map:

var map = L.map('map', {
    renderer: L.svg();
});

Use a SVG renderer with extra padding for specific vector geometries:

var map = L.map('map');
var myRenderer = L.svg({ padding: 0.5 });
var line = L.polyline( coordinates, { renderer: myRenderer } );
var circle = L.circle( center, { renderer: myRenderer } );

Canvas

Allows vector layers to be displayed with <canvas>. Inherits Renderer. Due to technical limitations, Canvas is not available in all web browsers, notably IE8, and overlapping geometries might not display properly in some edge cases.

Usage example

Use Canvas by default for all paths in the map:

var map = L.map('map', {
    renderer: L.canvas();
});

Use a Canvas renderer with extra padding for specific vector geometries:

var map = L.map('map');
var myRenderer = L.canvas({ padding: 0.5 });
var line = L.polyline( coordinates, { renderer: myRenderer } );
var circle = L.circle( center, { renderer: myRenderer } );

GeoJSON

Represents a GeoJSON object or an array of GeoJSON objects. Allows you to parse GeoJSON data and display it on the map. Extends FeatureGroup.

Usage example

L.geoJson(data, {
    style: function (feature) {
        return {color: feature.properties.color};
    }
}).bindPopup(function (layer) {
    return layer.feature.properties.description;
}).addTo(map);

Creation

Factory	Description
`L.geoJSON(<Object> geojson?, <GeoJSON options> options?)`	Creates a GeoJSON layer. Optionally accepts an object in GeoJSON format to display on the map (you can alternatively add it later with `addData` method) and an `options` object.

Options

Option	Type	Default	Description
`pointToLayer`	`Function`	`*`	A `Function` defining how GeoJSON points spawn Leaflet layers. It is internally called when data is added, passing the GeoJSON point feature and its `LatLng`. The default is to spawn a default `Marker`: `function(geoJsonPoint, latlng) { return L.marker(latlng); }`
`style`	`Function`	`*`	A `Function` defining the `Path options` for styling GeoJSON lines and polygons, called internally when data is added. The default value is to not override any defaults: `function (geoJsonFeature) { return {} }`
`onEachFeature`	`Function`	`*`	A `Function` that will be called once for each created `Feature`, after it has been created and styled. Useful for attaching events and popups to features. The default is to do nothing with the newly created layers: `function (feature, layer) {}`
`filter`	`Function`	`*`	A `Function` that will be used to decide whether to show a feature or not. The default is to show all features: `function (geoJsonFeature) { return true; }`
`coordsToLatLng`	`Function`	`*`	A `Function` that will be used for converting GeoJSON coordinates to `LatLng`s. The default is the `coordsToLatLng` static method.

▶ Options inherited from Layer

GridLayer

Generic class for handling a tiled grid of HTML elements. This is the base class for all tile layers and replaces TileLayer.Canvas. GridLayer can be extended to create a tiled grid of HTML elements like <canvas>, <img> or <div>. GridLayer will handle creating and animating these DOM elements for you.

Usage example

Synchronous usage

To create a custom layer, extend GridLayer and implement the createTile() method, which will be passed a Point object with the x, y, and z (zoom level) coordinates to draw your tile.

var CanvasLayer = L.GridLayer.extend({
    createTile: function(coords){
        // create a <canvas> element for drawing
        var tile = L.DomUtil.create('canvas', 'leaflet-tile');
        // setup tile width and height according to the options
        var size = this.getTileSize();
        tile.width = size.x;
        tile.height = size.y;
        // get a canvas context and draw something on it using coords.x, coords.y and coords.z
        var ctx = tile.getContext('2d');
        // return the tile so it can be rendered on screen
        return tile;
    }
});

Asynchronous usage

Tile creation can also be asynchronous, this is useful when using a third-party drawing library. Once the tile is finished drawing it can be passed to the done() callback.

var CanvasLayer = L.GridLayer.extend({
    createTile: function(coords, done){
        var error;
        // create a <canvas> element for drawing
        var tile = L.DomUtil.create('canvas', 'leaflet-tile');
        // setup tile width and height according to the options
        var size = this.getTileSize();
        tile.width = size.x;
        tile.height = size.y;
        // draw something asynchronously and pass the tile to the done() callback
        setTimeout(function() {
            done(error, tile);
        }, 1000);
        return tile;
    }
});

Functions

Function	Returns	Description
`extend(<Object> dest, <Object> src?)`	`Object`	Merges the properties of the `src` object (or multiple objects) into `dest` object and returns the latter. Has an `L.extend` shortcut.
`create(<Object> proto, <Object> properties?)`	`Object`	Compatibility polyfill for Object.create
`bind(<Function> fn, …)`	`Function`	Returns a new function bound to the arguments passed, like Function.prototype.bind. Has a `L.bind()` shortcut.
`stamp(<Object> obj)`	`Number`	Returns the unique ID of an object, assiging it one if it doesn't have it.
`throttle(<Function> fn, <Number> time, <Object> context)`	`Function`	Returns a function which executes function `fn` with the given scope `context` (so that the `this` keyword refers to `context` inside `fn`'s code). The function `fn` will be called no more than one time per given amount of `time`. The arguments received by the bound function will be any arguments passed when binding the function, followed by any arguments passed when invoking the bound function. Has an `L.bind` shortcut.
`wrapNum(<Number> num, <Number[]> range, <Boolean> includeMax?)`	`Number`	Returns the number `num` modulo `range` in such a way so it lies within `range[0]` and `range[1]`. The returned value will be always smaller than `range[1]` unless `includeMax` is set to `true`.
`falseFn()`	`Function`	Returns a function which always returns `false`.
`formatNum(<Number> num, <Number> digits?)`	`Number`	Returns the number `num` rounded to `digits` decimals, or to 5 decimals by default.
`trim(<String> str)`	`String`	Compatibility polyfill for String.prototype.trim
`splitWords(<String> str)`	`String[]`	Trims and splits the string on whitespace and returns the array of parts.
`setOptions(<Object> obj, <Object> options)`	`Object`	Merges the given properties to the `options` of the `obj` object, returning the resulting options. See `Class options`. Has an `L.setOptions` shortcut.
`getParamString(<Object> obj, <String> existingUrl?, <Boolean> uppercase?)`	`String`	Converts an object into a parameter URL string, e.g. `{a: "foo", b: "bar"}` translates to `'?a=foo&b=bar'`. If `existingUrl` is set, the parameters will be appended at the end. If `uppercase` is `true`, the parameter names will be uppercased (e.g. `'?A=foo&B=bar'`)
`template(<String> str, <Object> data)`	`String`	Simple templating facility, accepts a template string of the form `'Hello {a}, {b}'` and a data object like `{a: 'foo', b: 'bar'}`, returns evaluated string `('Hello foo, bar')`. You can also specify functions instead of strings for data values — they will be evaluated passing `data` as an argument.
`isArray(obj)`	`Boolean`	Compatibility polyfill for Array.isArray
`indexOf(<Array> array, <Object> el)`	`Number`	Compatibility polyfill for Array.prototype.indexOf
`requestAnimFrame(<Function> fn, <Object> context?, <Boolean> immediate?)`	`Number`	Schedules `fn` to be executed when the browser repaints. `fn` is bound to `context` if given. When `immediate` is set, `fn` is called immediately if the browser doesn't have native support for `window.requestAnimationFrame`, otherwise it's delayed. Returns a request ID that can be used to cancel the request.
`cancelAnimFrame(<Number> id)`	`undefined`	Cancels a previous `requestAnimFrame`. See also window.cancelAnimationFrame.

Properties

Property	Type	Description
`lastId`	`Number`	Last unique ID used by `stamp()`
`emptyImageUrl`	`String`	Data URI string containing a base64-encoded empty GIF image. Used as a hack to free memory from unused images on WebKit-powered mobile devices (by setting image `src` to this string).

Transformation

Represents an affine transformation: a set of coefficients a, b, c, d for transforming a point of a form (x, y) into (a*x + b, c*y + d) and doing the reverse. Used by Leaflet in its projections code.

Usage example

var transformation = new L.Transformation(2, 5, -1, 10),
    p = L.point(1, 2),
    p2 = transformation.transform(p), //  L.point(7, 8)
    p3 = transformation.untransform(p2); //  L.point(1, 2)

Methods

Method	Returns	Description
`transform(<Point> point, <Number> scale?)`	`Point`	Returns a transformed point, optionally multiplied by the given scale. Only accepts real `L.Point` instances, not arrays.
`untransform(<Point> point, <Number> scale?)`	`Point`	Returns the reverse transformation of the given point, optionally divided by the given scale. Only accepts real `L.Point` instances, not arrays.

Used for a huge performance boost when processing/displaying Leaflet polylines for each zoom level and also reducing visual noise. tolerance affects the amount of simplification (lesser value means higher quality but slower and with more points). Also released as a separated micro-library Simplify.js.
`pointToSegmentDistance(<Point> p, <Point> p1, <Point> p2)`	`Number`	Returns the distance between point `p` and segment `p1` to `p2`.
`closestPointOnSegment(<Point> p, <Point> p1, <Point> p2)`	`Number`	Returns the closest point from a point `p` on a segment `p1` to `p2`.
`clipSegment(<Point> a, <Point> b, <Bounds> bounds, <Boolean> useLastCode?, <Boolean> round?)`	`Point[]\|Boolean`	Clips the segment a to b by rectangular bounds with the Cohen-Sutherland algorithm (modifying the segment points directly!). Used by Leaflet to only show polyline points that are on the screen or near, increasing performance.

PolyUtil

Various utility functions for polygon geometries.

Functions

Function	Returns	Description
`clipPolygon(<Point[]> points, <Bounds> bounds, <Boolean> round?)`	`Point[]`	Clips the polygon geometry defined by the given `points` by the given bounds (using the Sutherland-Hodgeman algorithm). Used by Leaflet to only show polygon points that are on the screen or near, increasing performance. Note that polygon points needs different algorithm for clipping than polyline, so there's a seperate method for it.

DomEvent

Utility functions to work with the DOM events, used by Leaflet internally.

Functions

Function	Returns	Description
`on(<HTMLElement> el, <String> types, <Function> fn, <Object> context?)`	`this`	Adds a listener function (`fn`) to a particular DOM event type of the element `el`. You can optionally specify the context of the listener (object the `this` keyword will point to). You can also pass several space-separated types (e.g. `'click dblclick'`).
`on(<HTMLElement> el, <Object> eventMap, <Object> context?)`	`this`	Adds a set of type/listener pairs, e.g. `{click: onClick, mousemove: onMouseMove}`
`off(<HTMLElement> el, <String> types, <Function> fn, <Object> context?)`	`this`	Removes a previously added listener function. If no function is specified, it will remove all the listeners of that particular DOM event from the element. Note that if you passed a custom context to on, you must pass the same context to `off` in order to remove the listener.
`off(<HTMLElement> el, <Object> eventMap, <Object> context?)`	`this`	Removes a set of type/listener pairs, e.g. `{click: onClick, mousemove: onMouseMove}`
`stopPropagation(<DOMEvent> ev)`	`this`	Stop the given event from propagation to parent elements. Used inside the listener functions: `L.DomEvent.on(div, 'click', function (ev) { L.DomEvent.stopPropagation(ev); });`
`disableScrollPropagation(<HTMLElement> el)`	`this`	Adds `stopPropagation` to the element's `'mousewheel'` events (plus browser variants).
`disableClickPropagation(<HTMLElement> el)`	`this`	Adds `stopPropagation` to the element's `'click'`, `'doubleclick'`, `'mousedown'` and `'touchstart'` events (plus browser variants).
`preventDefault(<DOMEvent> ev)`	`this`	Prevents the default action of the DOM Event `ev` from happening (such as following a link in the href of the a element, or doing a POST request with page reload when a `<form>` is submitted). Use it inside listener functions.
`stop(ev)`	`this`	Does `stopPropagation` and `preventDefault` at the same time.
`getMousePosition(<DOMEvent> ev, <HTMLElement> container?)`	`Point`	Gets normalized mouse position from a DOM event relative to the `container` or to the whole page if not specified.
`getWheelDelta(<DOMEvent> ev)`	`Number`	Gets normalized wheel delta from a mousewheel DOM event, in vertical pixels scrolled (negative if scrolling down). Events from pointing devices without precise scrolling are mapped to a best guess of 60 pixels.
`addListener(…)`	`this`	Alias to `L.DomEvent.on`
`removeListener(…)`	`this`	Alias to `L.DomEvent.off`

DomUtil

Utility functions to work with the DOM tree, used by Leaflet internally. Most functions expecting or returning a HTMLElement also work for SVG elements. The only difference is that classes refer to CSS classes in HTML and SVG classes in SVG.

Functions

Function	Returns	Description
`get(<String\|HTMLElement> id)`	`HTMLElement`	Returns an element given its DOM id, or returns the element itself if it was passed directly.
`getStyle(<HTMLElement> el, <String> styleAttrib)`	`String`	Returns the value for a certain style attribute on an element, including computed values or values set through CSS.
`create(<String> tagName, <String> className?, <HTMLElement> container?)`	`HTMLElement`	Creates an HTML element with `tagName`, sets its class to `className`, and optionally appends it to `container` element.
`remove(<HTMLElement> el)`		Removes `el` from its parent element
`empty(<HTMLElement> el)`		Removes all of `el`'s children elements from `el`
`toFront(<HTMLElement> el)`		Makes `el` the last children of its parent, so it renders in front of the other children.
`toBack(<HTMLElement> el)`		Makes `el` the first children of its parent, so it renders back from the other children.
`hasClass(<HTMLElement> el, <String> name)`	`Boolean`	Returns `true` if the element's class attribute contains `name`.
`addClass(<HTMLElement> el, <String> name)`		Adds `name` to the element's class attribute.
`removeClass(<HTMLElement> el, <String> name)`		Removes `name` from the element's class attribute.
`setClass(<HTMLElement> el, <String> name)`		Sets the element's class.
`getClass(<HTMLElement> el)`	`String`	Returns the element's class.
`setOpacity(<HTMLElement> el, <Number> opacity)`		Set the opacity of an element (including old IE support). `opacity` must be a number from `0` to `1`.
`testProp(<String[]> props)`	`String\|false`	Goes through the array of style names and returns the first name that is a valid style name for an element. If no such name is found, it returns false. Useful for vendor-prefixed styles like `transform`.
`setTransform(<HTMLElement> el, <Point> offset, <Number> scale?)`		Resets the 3D CSS transform of `el` so it is translated by `offset` pixels and optionally scaled by `scale`. Does not have an effect if the browser doesn't support 3D CSS transforms.
`setPosition(<HTMLElement> el, <Point> position)`		Sets the position of `el` to coordinates specified by `position`, using CSS translate or top/left positioning depending on the browser (used by Leaflet internally to position its layers).
`getPosition(<HTMLElement> el)`	`Point`	Returns the coordinates of an element previously positioned with setPosition.
`disableTextSelection()`		Prevents the user from generating `selectstart` DOM events, usually generated when the user drags the mouse through a page with text. Used internally by Leaflet to override the behaviour of any click-and-drag interaction on the map. Affects drag interactions on the whole document.
`enableTextSelection()`		Cancels the effects of a previous `L.DomUtil.disableTextSelection`.
`disableImageDrag()`		As `L.DomUtil.disableTextSelection`, but for `dragstart` DOM events, usually generated when the user drags an image.
`enableImageDrag()`		Cancels the effects of a previous `L.DomUtil.disableImageDrag`.
`preventOutline(<HTMLElement> el)`		Makes the outline of the element `el` invisible. Used internally by Leaflet to prevent focusable elements from displaying an outline when the user performs a drag interaction on them.
`restoreOutline()`		Cancels the effects of a previous `L.DomUtil.preventOutline`.

Class

L.Class powers the OOP facilities of Leaflet and is used to create almost all of the Leaflet classes documented here. In addition to implementing a simple classical inheritance model, it introduces several special properties for convenient code organization — options, includes and statics.

Usage example

var MyClass = L.Class.extend({
initialize: function (greeter) {
    this.greeter = greeter;
    // class constructor
},
greet: function (name) {
    alert(this.greeter + ', ' + name)
    }
});
// create instance of MyClass, passing "Hello" to the constructor
var a = new MyClass("Hello");
// call greet method, alerting "Hello, World"
a.greet("World");

Class Factories

You may have noticed that Leaflet objects are created without using the new keyword. This is achieved by complementing each class with a lowercase factory method:

new L.Map('map'); // becomes:
L.map('map');

The factories are implemented very easily, and you can do this for your own classes:

L.map = function (id, options) {
    return new L.Map(id, options);
};

Inheritance

You use L.Class.extend to define new classes, but you can use the same method on any class to inherit from it:

var MyChildClass = MyClass.extend({
    // ... new properties and methods
});

This will create a class that inherits all methods and properties of the parent class (through a proper prototype chain), adding or overriding the ones you pass to extend. It will also properly react to instanceof:

var a = new MyChildClass();
a instanceof MyChildClass; // true
a instanceof MyClass; // true

You can call parent methods (including constructor) from corresponding child ones (as you do with super calls in other languages) by accessing parent class prototype and using JavaScript's call or apply:

var MyChildClass = MyClass.extend({
    initialize: function () {
        MyClass.prototype.initialize.call(this, "Yo");
    },
    greet: function (name) {
        MyClass.prototype.greet.call(this, 'bro ' + name + '!');
    }
});
var a = new MyChildClass();
a.greet('Jason'); // alerts "Yo, bro Jason!"

Options

options is a special property that unlike other objects that you pass to extend will be merged with the parent one instead of overriding it completely, which makes managing configuration of objects and default values convenient:

var MyClass = L.Class.extend({
    options: {
        myOption1: 'foo',
        myOption2: 'bar'
    }
});
var MyChildClass = L.Class.extend({
    options: {
        myOption1: 'baz',
        myOption3: 5
    }
});
var a = new MyChildClass();
a.options.myOption1; // 'baz'
a.options.myOption2; // 'bar'
a.options.myOption3; // 5

There's also L.Util.setOptions, a method for conveniently merging options passed to constructor with the defaults defines in the class:

var MyClass = L.Class.extend({
    options: {
        foo: 'bar',
        bla: 5
    },
    initialize: function (options) {
        L.Util.setOptions(this, options);
        ...
    }
});
var a = new MyClass({bla: 10});
a.options; // {foo: 'bar', bla: 10}

Includes

includes is a special class property that merges all specified objects into the class (such objects are called mixins).

 var MyMixin = {
    foo: function () { ... },
    bar: 5
};
var MyClass = L.Class.extend({
    includes: MyMixin
});
var a = new MyClass();
a.foo();

You can also do such includes in runtime with the include method:

MyClass.include(MyMixin);

statics is just a convenience property that injects specified object properties as the static properties of the class, useful for defining constants:

var MyClass = L.Class.extend({
    statics: {
        FOO: 'bar',
        BLA: 5
    }
});
MyClass.FOO; // 'bar'

Constructor hooks

If you're a plugin developer, you often need to add additional initialization code to existing classes (e.g. editing hooks for L.Polyline). Leaflet comes with a way to do it easily using the addInitHook method:

MyClass.addInitHook(function () {
    // ... do something in constructor additionally
    // e.g. add event listeners, set custom properties etc.
});

You can also use the following shortcut when you just need to make one additional method call:

MyClass.addInitHook('methodName', arg1, arg2, …);

Functions

Function	Returns	Description
`extend(<Object> props)`	`Function`	Extends the current class given the properties to be included. Returns a Javascript function that is a class constructor (to be called with `new`).
`include(<Object> properties)`	`this`	Includes a mixin into the current class.
`mergeOptions(<Object> options)`	`this`	Merges `options` into the defaults of the class.
`addInitHook(<Function> fn)`	`this`	Adds a constructor hook to the class.

Evented

A set of methods shared between event-powered classes (like Map and Marker). Generally, events allow you to execute some function when something happens with an object (e.g. the user clicks on the map, causing the map to fire 'click' event).

Usage example

map.on('click', function(e) {
    alert(e.latlng);
} );

Leaflet deals with event listeners by reference, so if you want to add a listener and then remove it, define it as a function:

function onClick(e) { ... }
map.on('click', onClick);
map.off('click', onClick);

Methods

Extension methods

Every layer should extend from L.Layer and (re-)implement the following methods.

Control

L.Control is a base class for implementing map controls. Handles positioning. All other controls extend from this class.

Options

Option	Type	Default	Description
`position`	`String`	`'topright'`	The position of the control (one of the map corners). Possible values are `'topleft'`, `'topright'`, `'bottomleft'` or `'bottomright'`

Methods

Classes extending L.Control will inherit the following methods:

Method	Returns	Description
`getPosition()`	`string`	Returns the position of the control.
`setPosition(<string> position)`	`this`	Sets the position of the control.
`getContainer()`	`HTMLElement`	Returns the HTMLElement that contains the control.
`addTo(<Map> map)`	`this`	Adds the control to the given map.
`remove()`	`this`	Removes the control from the map it is currently active on.

Extension methods

Every control should extend from L.Control and (re-)implement the following methods.

Method	Returns	Description
`onAdd(<Map> map)`	`HTMLElement`	Should return the container DOM element for the control and add listeners on relevant map events. Called on `control.addTo(map)`.
`onRemove(<Map> map)`		Optional method. Should contain all clean up code that removes the listeners previously added in `onAdd`. Called on `control.remove()`.

Methods

Method	Returns	Description

`unproject(<Point> point)`	`LatLng`	The inverse of `project`. Projects a 2D point into a geographical location.

Properties

Property	Type	Description
`bounds`	`LatLngBounds`	The bounds where the projection is valid

Defined projections

Leaflet comes with a set of already defined Projections out of the box:

Projection	Description
`L.Projection.LonLat`	Equirectangular, or Plate Carree projection — the most simple projection, mostly used by GIS enthusiasts. Directly maps `x` as longitude, and `y` as latitude. Also suitable for flat worlds, e.g. game maps. Used by the `EPSG:3395` and `Simple` CRS.
`L.Projection.Mercator`	Elliptical Mercator projection — more complex than Spherical Mercator. Takes into account that Earth is a geoid, not a perfect sphere. Used by the EPSG:3395 CRS.
`L.Projection.SphericalMercator`	Spherical Mercator projection — the most common projection for online maps, used by almost all free and commercial tile providers. Assumes that Earth is a sphere. Used by the `EPSG:3857` CRS.

CRS

Abstract class that defines coordinate reference systems for projecting geographical points into pixel (screen) coordinates and back (and to coordinates in other units for WMS services). See spatial reference system. Leaflet defines the most usual CRSs by default. If you want to use a CRS not defined by default, take a look at the Proj4Leaflet plugin.

Methods

Method	Returns	Description
`latLngToPoint(<LatLng> latlng, <Number> zoom)`	`Point`	Projects geographical coordinates into pixel coordinates for a given zoom.
`pointToLatLng(<Point> point, <Number> zoom)`	`LatLng`	The inverse of `latLngToPoint`. Projects pixel coordinates on a given zoom into geographical coordinates.
`project(<LatLng> latlng)`	`Point`	Projects geographical coordinates into coordinates in units accepted for this CRS (e.g. meters for EPSG:3857, for passing it to WMS services).
`unproject(<Point> point)`	`LatLng`	Given a projected coordinate returns the corresponding LatLng. The inverse of `project`.
`scale(<Number> zoom)`	`Number`	Returns the scale used when transforming projected coordinates into pixel coordinates for a particular zoom. For example, it returns `256 * 2^zoom` for Mercator-based CRS.
`zoom(<Number> scale)`	`Number`	Inverse of `scale()`, returns the zoom level correspondingto a scale factor of `scale`.
`getProjectedBounds(zoom)`	`Bounds`	Returns the projection's bounds scaled and transformed for the provided `zoom`.
`distance(<LatLng> latlng1)`	`Number`	Returns the distance between two geographical coordinates.
`wrapLatLng(<LatLng> latlng)`	`LatLng`	Returns a `LatLng` where lat and lng has been wrapped according to the CRS's `wrapLat` and `wrapLng` properties, if they are outside the CRS's bounds.

Properties

Property	Type	Description
`code`	`String`	Standard code name of the CRS passed into WMS services (e.g. `'EPSG:3857'`)
`wrapLng`	`Number[]`	An array of two numbers defining whether the longitude coordinate axis wraps around a given range and how. Defaults to `[-180, 180]` in most geographical CRSs.
`wrapLat`	`Number[]`	Like `wrapLng`, but for the latitude axis.
`infinite`	`Boolean`	If true, the coordinate space will be unbounded (infinite in both axes)

Defined CRSs

CRS	Description
`L.CRS.EPSG3395`	Rarely used by some commercial tile providers. Uses Elliptical Mercator projection.
`L.CRS.EPSG3857`	The most common CRS for online maps, used by almost all free and commercial tile providers. Uses Spherical Mercator projection. Set in by default in Map's `crs` option.
`L.CRS.EPSG4326`	A common CRS among GIS enthusiasts. Uses simple Equirectangular projection.
`L.CRS.Earth`	Serves as the base for CRS that are global such that they cover the earth. Can only be used as the base for other CRS and cannot be used directly, since it does not have a `code`, `projection` or `transformation`. `distance()` returns meters.
`L.CRS.Simple`	A simple CRS that maps longitude and latitude into `x` and `y` directly. May be used for maps of flat surfaces (e.g. game maps). Note that the `y` axis should still be inverted (going from bottom to top). `distance()` returns simple euclidean distance.

Renderer

Base class for vector renderer implementations (SVG, Canvas). Handles the DOM container of the renderer, its bounds, and its zoom animation. A Renderer works as an implicit layer group for all Paths - the renderer itself can be added or removed to the map. All paths use a renderer, which can be implicit (the map will decide the type of renderer and use it automatically) or explicit (using the renderer option of the path). Do not use this class directly, use SVG and Canvas instead.

Options

Option	Type	Default	Description
`padding`	`Number`	`0.1`	How much to extend the clip area around the map view (relative to its size) e.g. 0.1 would be 10% of map view in each direction

▶ Options inherited from Layer

Option	Type	Default	Description

Global Switches

Global switches are created for rare cases and generally make Leaflet to not detect a particular browser feature even if it's there. You need to set the switch as a global variable to true before including Leaflet on the page, like this:

<script>L_NO_TOUCH = true;</script>
<script src="leaflet.js"></script>

Switch	Description
`L_NO_TOUCH`	Forces Leaflet to not use touch events even if it detects them.
`L_DISABLE_3D`	Forces Leaflet to not use hardware-accelerated CSS 3D transforms for positioning (which may cause glitches in some rare environments) even if they're supported.

noConflict

This method restores the L global variable to the original value it had before Leaflet inclusion, and returns the real Leaflet namespace so you can put it elsewhere, like this:

<script src='libs/l.js'>
<!-- L points to some other library -->
<script src='leaflet.js'>
<!-- you include Leaflet, it replaces the L variable to Leaflet namespace -->
<script>
var Leaflet = L.noConflict();
// now L points to that other library again, and you can use Leaflet.Map etc.
</script>

version

A constant that represents the Leaflet version in use.

L.version; // contains "1.0.0" (or whatever version is currently in use)
