Question

I am using Drupal 7 – Location, GMap module. I have a view that renders the result in a gmap. Everything works fine here and I get all the markers. Now I need a Find My location button which shows the users current location and adds a marker to the existing map.
Google Map Api V3 always works on a newly created map and I couldn’t find a function which returns an existing map in the current page.

Gmap module provides a JS function – Drupal.gmap.getMap(‘ur-map-id’) which is supposed to return a pointer to the map whose id is given. But this did not work.

Could someone please guide me as to how I should go about this? Can I get it work with Google Maps API? I need to retain the original map with all its markers.

I am having this issue as well, you can put this jquery code in for it to actually centre around your current location – but no marker is added. Just add it anywhere in your theme,

jQuery(document).ready(function() {

jQuery(function($) {
$.extend({
initialize: function () {
var m = Drupal.gmap.getMap('auto1map');
if (m.map && m.markersready) {
$.setCoords();
}
else {
m.bind('markersready', function(data) {
$.setCoords();
});
}
},
setCoords: function () {
navigator.geolocation.getCurrentPosition(function (position) {
var gmap = Drupal.gmap.getMap('auto1map').map;
var lat = position.coords.latitude;
var lng = position.coords.longitude;
gmap.setCenter(new google.maps.LatLng(lat, lng));
gmap.setZoom(13);
});
}
});
$.initialize();
});

});

Now you can centre your map around your location and now I need to figure out a way to place a marker down at this location.
