[OpenLayers-Users] problem with map.setCenter(....

Mon Mar 22 15:21:23 EDT 2010

Hi all,

I want to have a button. And after you press the butten the map should move
to the new Center.
But I geta error in Firebug: "map is undefined", after I pressed the button.
I tried different strategies but nothing worked. When I do the same thing
with a variable like  var a=3 it works....
please help me.

The Code is like this:

<html>
<head>
  <title>Test</title>

  <style type="text/css">

	#map{
		width:100%;
		height:600px;
		border:1px solid;
	} 
</style>

    <script src="http://openlayers.org/api/OpenLayers.js"></script>

	 <script  defer="defer" type="text/javascript">

function load(mode){

	if (mode=="start"){

	...
	.
	.		
		var map = new OpenLayers.Map('map',options);

		var wms = new OpenLayers.Layer.WMS(...
		.
		.
		.

		map.addLayer(wms);

		map.zoomToMaxExtent();
                //map.setCenter(new OpenLayers.LonLat(145,-40),8);//here
would be know error!

	}
	else if (mode=="newPos"){
		map.setCenter(new OpenLayers.LonLat(145,-40),8);//-->error: map is
undefined!
	}

}

      </script>

    </head>

    <body onload="load('start')">

	<table width="100%" border="0">
		<tr>
			<td colspan="2" height="100">TITEL</td>
		</tr>
		<tr>
			<td width="20%">					
			<input type="button" value="Go" onClick="load('newPos')"> 				
			</td>
			<td><div id="map"></div></td>
		</tr>
	</table>
    </body>
</html>
