Centered by exposed filter

Regarding the issue user friendly input and the patch googlemaps-widget-1415244-4.patch in the issue, it will be great if we can center the map each time we click 'Get location' based on the value in location field.

I have made a js file to do it. But it needs a tweak in ip_geoloc module. I have posted a message in the issue queue there, hopefully the map object will be available in current window.

Following is my js file. Please let me know if I am logically wrong.

Drupal.behaviors.geolocation_proximity = {
  attach: function(context) {
    var $ = jQuery;
    $('.geolocation-address-geocode').click(function() {
      var location = $('.geolocation-address :input').val();
      geocoder = new google.maps.Geocoder();
      geocoder.geocode( { 'address': location }, function(results, status) {
        if (status == google.maps.GeocoderStatus.OK) {
          map.setCenter(results[0].geometry.location);
        }
      });
    });
  }
}
