google map v3 is not fully displayed in html5, phonegap.![enter image description here](https://i.stack.imgur.com/3m207.png)

This map is drag-able, here is JavaScript code(main.js)

```
 var map;
 function initialize() {
 var myLatlng = new google.maps.LatLng(-25.363882,131.044922);
 var myLatlng2 = new google.maps.LatLng(-24.363882,131.044922);

 var myOptions = {
 center: myLatlng,
 zoom:5,
 mapTypeId: google.maps.MapTypeId.ROADMAP

 };
 map = new google.maps.Map(document.getElementById("map_canvas"),
 myOptions);

 setMarker(myLatlng);
 setMarker(myLatlng2);

 }

 function setMarker(p)
 {
 marker = new google.maps.Marker({
 position: p,
 title:"Hello World 2!"
 });
 marker.setMap(map);

 }

 initialize();

```

and here is my html 

```

    -webkit-box-shadow: rgba(64, 64, 64, 0.5) 0 2px 5px;
    -moz-box-shadow: rgba(64, 64, 64, 0.5) 0 2px 5px;
    box-shadow: rgba(64, 64, 64, 0.1) 0 2px 5px;
    width: 600px;
  }

  #map_canvas {
