[google-maps] Google Maps API OVER QUERY LIMIT per second limit

This approach is not correct beacuse of Google Server Overload. For more informations see https://gis.stackexchange.com/questions/15052/how-to-avoid-google-map-geocode-limit#answer-15365

By the way, if you wish to proceed anyway, here you can find a code that let you load multiple markers ajax sourced on google maps avoiding OVER_QUERY_LIMIT error.

I've tested on my onw server and it works!:

var lost_addresses = [];
    geocode_count  = 0;
    resNumber = 0;
    map = new GMaps({
       div: '#gmap_marker',
       lat: 43.921493,
       lng: 12.337646,
    });

function loadMarkerTimeout(timeout) {
    setTimeout(loadMarker, timeout)
}

function loadMarker() { 
    map.setZoom(6);         
    $.ajax({
            url: [Insert here your URL] ,
            type:'POST',
            data: {
                "action":   "loadMarker"
            },
            success:function(result){

                /***************************
                 * Assuming your ajax call
                 * return something like: 
                 *   array(
                 *      'status' => 'success',
                 *      'results'=> $resultsArray
                 *   );
                 **************************/

                var res=JSON.parse(result);
                if(res.status == 'success') {
                    resNumber = res.results.length;
                    //Call the geoCoder function
                    getGeoCodeFor(map, res.results);
                }
            }//success
    });//ajax
};//loadMarker()

$().ready(function(e) {
  loadMarker();
});

//Geocoder function
function getGeoCodeFor(maps, addresses) {
        $.each(addresses, function(i,e){                
                GMaps.geocode({
                    address: e.address,
                    callback: function(results, status) {
                            geocode_count++;        

                            if (status == 'OK') {       

                                //if the element is alreay in the array, remove it
                                lost_addresses = jQuery.grep(lost_addresses, function(value) {

                            } else if (status == 'ZERO_RESULTS') {
                                //alert('Sorry, no results found');
                            } else if(status == 'OVER_QUERY_LIMIT') {

                                //if the element is not in the losts_addresses array, add it!
