#Examples (require src/leaflet-search.css)

Adding the search control to the map:

map.addControl( new L.Control.Search({layer: searchLayer}) );
//searchLayer is a L.LayerGroup contains searched markers

Short way:

var map = new L.Map('map', { searchControl: {layer: searchLayer} });

#Advanced Examples

Ajax request to search.php for retrieve elements locations:

map.addControl( new L.Control.Search({url: 'search.php?q={s}'}) );

Request to third party JSONP service, implements Geocode Searching using OSM API:

map.addControl( new L.Control.Search({
	url: 'http://nominatim.openstreetmap.org/search?format=json&q={s}',
	jsonpParam: 'json_callback',
	propertyName: 'display_name',
	propertyLoc: ['lat','lon']
}) );

Search and color features vector in GeoJSON layer:

var searchControl = new L.Control.Search({layer: geojsonLayer, circleLocation:false});

searchControl.on('search_locationfound', function(e) {
	
	e.layer.setStyle({fillColor: '#3f0'});

}).on('search_collapsed', function(e) {

	featuresLayer.eachLayer(function(layer) {
		featuresLayer.resetStyle(layer);
	});	
});

map.addControl(searchControl);

Static data source:

var data = [
	{"loc":[41.575330,13.102411], "title":"aquamarine"},
	{"loc":[41.575730,13.002411], "title":"black"},
	{"loc":[41.219190,13.062145], "title":"cyan"}
];

map.addControl(new L.Control.Search({
	markerLocation: true,
	callData: function(text, callResponse) {
		
		//here can use custom criteria or merge data from multiple layers

		callResponse(data);

		return {	//called to stop previous requests on map move
			abort: function() {
				console.log('aborted request:'+ text);
			}
		};
	}
}) );
