I'm using Leaflet JS to build my maps, but I'm having a few issues selecting layers.
I'm aiming to fit my map to a polygon. Leaflet generates a Leaflet ID for each element on the map, but these IDs are random. So I want to create an array which links each Leaflet ID with a known polygon ID.
The concept comes from here How to interact with leaflet marker layer from outside the map? but I'm unsure how to implement it.
The object 'map._layers' stores all the elements including the ID of each polygon. So I'm looping through it as follows:
var idstore = [];
for (var x in map._layers) {
// here idstore[x['polyid']] = x;
}
Now I can use that array to associate my polygon IDs to Leaflet IDs. The resulting array should be as follows:
array('polygonid'=>'leafletid','155447'=>'478','748745' => 479);
My problem is the loop isn't working correctly. I can only see the first 2 records coming up which are actually overlays (map tiles). The elements are definitely in that object though.
What am I doing wrong?
