  }



  </script>

here is the HTML code

<div id="map_govinda">
        <div id="default"></div>
    </div>

here are the locations, lat-longs are coming from the database.

I always avoid initializing the map when the map canvas is not visible (yet).
Usually this can be solved with trigger(map, 'resize') ... , which you already tried.

Try this: initialize the map only after the click on "map.png"

so remove this: body onload="initialize()", and try this

$("#go_map").click(function(){
    $("#cate_list_view").hide(1000);
    $("#go_map").hide(1000);
    $("#map_govinda").show(1000, function() {
      // we'll wait until the canvas for the map is fully visible
      if(! map) {  // this will only trigger once
        initialize();
      }
    });
    $("#go_list").show(1000);
});

var map;  // put the map object somewhere global, so we can access it anywhere

function initialize() {
  var myOptions = {
    center: new google.maps.LatLng(31.779966,35.221211),
    zoom: 10,
    mapTypeId: google.maps.MapTypeId.ROADMAP
  };
  map = new google.maps.Map(document.getElementById("default"), myOptions);
  setMarkers(map,locations);
}
