传单地理搜索：从找到的地址事件中返回经纬度

Question

I use great Leaflet plugins for geocoding such as https://github.com/smeijer/L.GeoSearch

While these are perfect for showing address locations on the map when found, I would also like to be able to use the coordinates from the result to other functions that I have included in my map (eg I've written one which finds nearby points from a data layer based on the locationfound event fired from Leaflet's inbuilt locate function).

I know the answer (probably) lies in accessing the events from the geosearch plugin, but that's a bit beyond my skills at the moment. Any help would be very welcome.

Answer 1

The L.GeoSearch plugin fires it's events on your map instance. You'll need to listen for the geosearch_foundlocations event. The object that's returned when the event is fired holds a Locations property which contains an array with L.GeoSearch.Result objects. Each object has four properties; Label , X , Y and bounds

Example in code:

map.on('geosearch_foundlocations', function (e) {
    e.Locations.forEach(function (Location) {
        // Location.Label = full address
        // Location.X = longitude
        // Location.Y = latitude
        // Location.bounds = boundaries
    });
});
