< h3 > Implementing Custom Layers< / h3 >
< p > The most important things know about when implementing custom layers are Map < a href = "#map-viewreset" > viewreset< / a > event and < a href = "#map-latlngtolayerpoint" > latLngToLayerPoint< / a > method. < code > viewreset< / code > is fired when the map needs to reposition its layers (e.g. on zoom), and < code > latLngToLayerPoint< / code > is used to get coordinates for the layer's new position.< / p >
2012-08-20 20:46:00 +08:00
< p > Another event often used in layer implementations is < a href = "#map-moveend" > moveend< / a > which fires after any movement of the map (panning, zooming, etc.).< / p >
2012-07-23 22:22:08 +08:00
< p > Another thing to note is that you'll usually need to add < code > leaflet-zoom-hide< / code > class to the DOM elements you create for the layer so that it hides during zoom animation. Implementing zoom animation for custom layers is a complex topic and will be documented separately in future, but meanwhile you can take a look at how it's done for Leaflet layers (e.g. < code > ImageOverlay< / code > ) in the source.< / p >
< h3 > Custom Layer Example< / h3 >
< p > Here's how a custom layer implementation usually looks:< / p >
< pre > < code > var MyCustomLayer = L.Class.extend({
initialize: function (latlng) {
// save position of the layer or any options from the constructor
this._latlng = latlng;
},
onAdd: function (map) {
this._map = map;
// create a DOM element and put it into one of the map panes
this._el = L.DomUtil.create('div', 'my-custom-layer leaflet-zoom-hide');
map.getPanes().overlayPane.appendChild(this._el);
// add a viewreset event listener for updating layer's position, do the latter
map.on('viewreset', this._reset, this);
this._reset();
},
onRemove: function (map) {
// remove layer's DOM elements and listeners
map.getPanes().overlayPane.removeChild(this._el);
map.off('viewreset', this._reset, this);
},
_reset: function () {
// update layer's position
var pos = this._map.latLngToLayerPoint(this._latlng);
L.DomUtil.setPosition(this._el, pos);
}
});
