Problem with displaying Google Maps in Visualforce Page.

Hi,

 

I'm having problem with displaying google maps in visualforce page. Here its not taking the body onload function in visualforce page. i tried a example in that when i add the maps using the body onload() its not getting displayed, but when i call the unload function on button click i'm able to display the map.

 

Now, i want to display the map on onLoad() function.

 

 

<apex:page standardController="Contact" extensions="ContactSearch1">


<html xmlns="http://www.w3.org/1999/xhtml" xmlns:v="urn:schemas-microsoft-com:vml">
  <head>
    <meta http-equiv="content-type" content="text/html; charset=utf-8"/>
    <title>Google Maps API Sample</title>
    <script src="http://maps.google.com/maps?file=api&amp;v=2&amp;sensor=false&amp;key=ABQIAAAAAiEBi5EXD6nh-EO4LuyxtBQWey-B1ZKQhVHInL6_tETDfQStQxR6nhjXEiIksVJNl42THPBptibDMw"></script>
    <script type="text/javascript">

    function initialize() {
      if (GBrowserIsCompatible()) {
        var map = new GMap2(document.getElementById("map_canvas"));
        map.setCenter(new GLatLng(37.4419, -122.1419), 13);
      }
    }

    </script>
  </head>
  <body onload="initialize()" onunload="GUnload()" style="font-family: Arial;border: 0 none;">
    <div id="map_canvas" style="width: 500px; height: 300px"></div>
	
	<input type="button" value="Show Map" Onclick="initialize()">    //When i click on the button i'm able to displayy the map in Visualforce page....

  </body>
</html>


</apex:page>
 
 
Please help me to load the maps on visualforce page loads.
 
Thank You.

I don't think you can use a body tag if you are using standard salesforce headers.
 
You'll need to set the showHeader attribute on the page tag to false to use a body tag in this way, or add the load/onload handlers using javascript instead.

From this thread, it looks like what you want is something like the following code in your Visualforce page:
 
 
<script>        var previousOnload = window.onload;            window.onload = function() {         if (previousOnload) {             previousOnload();        }    initialize();    }</script>
 
 That looks like it will hook into the body's onload function cleanly.
