L.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 = new L.Map('map', {
	center: new L.LatLng(51.505, -0.09),
	zoom: 13
});

// create a CloudMade tile layer
var cloudmadeUrl = 'http://{s}.tile.cloudmade.com/YOUR-API-KEY/997/256/{z}/{x}/{y}.png',
	cloudmade = new L.TileLayer(cloudmadeUrl, {maxZoom: 18});

// add the CloudMade layer to the map
map.addLayer(cloudmade);

Constructor

Constructor	Description
`L.Map( <HTMLElement\|String> id, <Map options> options? )`	Instantiates a map object given a div element (or its id) and optionally an object literal with map options described below.

Options

Option	Type	Default value	Description
`center`	`LatLng`	`null`	Initial geographical center of the map.
`zoom`	`Number`	`null`	Initial map zoom.

`minZoom`	`Number`	`0`	Minimum zoom level of the map. Overrides any `minZoom` set on map layers.
`maxZoom`	`Number`	`18`	Maximum zoom level of the map. This overrides any `maxZoom` set on map layers.
`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, and also not allowing to zoom out to a view that's larger than the given bounds (depending on the map size). To set the restriction dynamically, use setMaxBounds method
`crs`	`CRS`	`L.CRS.EPSG3857`	Coordinate Reference System to use. Don't change this if you're not sure what it means.
`dragging`	`Boolean`	`true`	Whether the map be draggable with mouse/touch or not.
`touchZoom`	`Boolean`	`true`	Whether the map can be zoomed by touch-dragging with two fingers.
`scrollWheelZoom`	`Boolean`	`true`	Whether the map can be zoomed by using the mouse wheel.

	cloudmade = new L.TileLayer(cloudmadeUrl, {maxZoom: 18});

Constructor

Constructor	Description
`L.TileLayer( <String> urlTemplate, <TileLayer options> options? )`	Instantiates a tile layer object given a URL template and optionally an options object.

URL template

A string of the following form:

'http://{s}.somedomain.com/blabla/{z}/{x}/{y}.png'

{s} means one of the randomly chosen subdomains (their range is specified in options; a, b or c by default, can be omitted), {z} — zoom level, {x} and {y} — tile coordinates.

You can use custom keys in the template, which will be evaluated from TileLayer options, like this:

new L.TileLayer('http://{s}.somedomain.com/{foo}/{z}/{x}/{y}.png', {foo: 'bar'});

Options

Option	Type	Default value	Description
`minZoom`	`Number`	`0`	Minimum zoom number.
`maxZoom`	`Number`	`18`	Maximum zoom number.
`tileSize`	`Number`	`256`	Tile size (width and height in pixels, assuming tiles are square).
`subdomains`	`String` or `String[]`	`'abc'`	Subdomains of the tile service. Can be passed in the form of one string (where each letter is a subdomain name) or an array of strings.
`errorTileUrl`	`String`	`''`	URL to the tile image to show in place of the tile that failed to load.
`attribution`	`String`	`''`	e.g. "© CloudMade" — the string used by the attribution control, describes the layer data.
`scheme`	`String`	`'xyz'`	Either `'xyz'` or `'tms'`, affects tile numbering (TMS servers use inverse Y axis numbering).
`continuousWorld`	`Boolean`	`false`	If set to `true`, the tile coordinates won't be wrapped by world width (-180 to 180 longitude) or clamped to lie within world height (-90 to 90). Use this if you use Leaflet for maps that don't reflect the real world (e.g. game, indoor or photo maps).
`noWrap`	`Boolean`	`false`	If set to `true`, the tiles just won't load outside the world width (-180 to 180 longitude) instead of repeating.
`zoomOffset`	`Number`	`0`	The zoom number used in tile URLs will be offset with this value.
`zoomReverse`	`Boolean`	`false`	If set to `true`, the zoom number used in tile URLs will be reversed (`maxZoom - zoom` instead of `zoom`)
`opacity`	`Number`	`1.0`	The opacity of the tile layer.
`unloadInvisibleTiles`	`Boolean`	depends	If `true`, all the tiles that are not visible after panning are removed (for better performance). `true` by default on mobile WebKit, otherwise `false`.
`updateWhenIdle`	`Boolean`	depends	If `false`, new tiles are loaded during panning, otherwise only after it (for better performance). `true` by default on mobile WebKit, otherwise `false`.
`reuseTiles`	`Boolean`	false	If `true`, all the tiles that are not visible after panning are placed in a reuse queue from which they will be fetched when new tiles become visible (as opposed to dynamically creating new ones). This will in theory keep memory usage low and eliminate the need for reserving new memory whenever a new tile is needed.

Methods

Method	Returns	Description
`setOpacity( <Number> opacity )`	`this`	Changes the opacity of the tile layer.
`redraw()`	-	Calling `redraw` will cause the `drawTile` method to be called for all tiles. May be used for updating dynamic content drawn on the Canvas

	"CloudMade": cloudmade,
	"OpenStreetMap": osm
};

var overlays = {
	"Marker": marker,
	"Roads": roadsLayer
};

layersControl = new L.Control.Layers(baseLayers, overlays);

map.addControl(layersControl);

Constructor

Constructor	Description

Layer Config

An object literal with layer names as keys and layer objects as values:

{
	"<someName1>": layer1,
	"<someName2>": layer2
}

Events methods

A set of methods shared between event-powered classes (like Map). 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 'fire' event).

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

Method	Returns	Description
`addEventListener( <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).
`removeEventListener( <String> type, <Function> fn, <Object> context? )`	`this`	Removes a previously added listener function.
`on( … )`	`this`	Alias to `addEventListener`.
`off( … )`	`this`	Alias to `removeEventListener`.
`hasEventListeners( <String> type )`	`Boolean`	Returns true if a particular event type has some listeners attached to it.
`fireEvent( <String> type, <Object> data? )`	`this`	Fires an event of the specified type. You can optionally provide an data object — the first argument of the listener function will contain its properties.
`fire( … )`	`this`	Alias to `fireEvent`.

Event objects

Event object is an object that you recieve as an argument in a listener function when some event is fired, containing useful information about that event. For example:

map.on('click', function(e) {
	alert(e.latlng); // e is an event object (MouseEvent in this case)
});

Event

The base event object. All other event objects contain these properties too.

property	type	description
`type`	`String`	The event type (e.g. "click").
`target`	`Object`	The object that fired the event.

MouseEvent

`geometryType`	`String`	GeoJSON geometry type of the feature.
`id`	`String`	GeoJSON ID of the feature (if present).

property	type	description
`popup`	`Popup`	The popup that was opened or closed.

L.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.

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");

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("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 defauls 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). A good example of this is L.Mixin.Events that event-related methods like on, off and fire to the class.

 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

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'

L.Browser

A namespace with properties for browser/feature detection used by Leaflet internally.

if (L.Browser.ie6) {
	alert('Upgrade your browser, dude!');
}

property	type	description
`ie`	`Boolean`	`true` for all old Internet Explorer versions (6-8).
`ie6`	`Boolean`	`true` for Internet Explorer 6.
`webkit`	`Boolean`	`true` for webkit-based browsers like Chrome and Safari (including mobile versions).

`mobileWebkit`	`Boolean`	`true` for mobile webkit-based browsers.
`mobileOpera`	`Boolean`	`true` for mobile Opera.
`touch`	`Boolean`	`true` for all browsers on touch devices.

IHandler

An interface implemented by interaction handlers.

Method	Returns	Description
`enable()`	-	Enables the handler.
`disable()`	-	Disables the handler.
`enabled()`	`Boolean`	Returns true if the handler is enabled.

L.VERSION

A constant that represents the Leaflet version in use.

L.VERSION // returns "0.3" (or whatever version is currently in use)

L.noConflict()

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

// L points to some other library
...
// you include Leaflet, it replaces the L variable to Leaflet namespace

var Leaflet = L.noConflict(); 
// now L points to that other library again, and you can use Leaflet.Map etc.
