[worldKit-dev] 3 layer switch

Tue Sep 25 13:59:51 PDT 2007

Mikel,

Thanks for hint. This is sort of where we're going...

<SCRIPT type=text/javascript>
//
var moldlayer='Elementary';
function activate(mnewlayer) 
{
	// turn off the previously selected layer
	// & turn on the newly selected layer 
	document.worldkit.SetVariable("JLayComm",moldlayer);
	document.worldkit.SetVariable("JLayComm",mnewlayer);
	//  alert("Turn on layer: " + mnewlayer + " / Turn off layer: " +
moldlayer); // for testing;
    moldlayer = mnewlayer ; 
 }
function echeck()
{	// check default layer when page is loaded or reloaded
	document.schoolmap.getspan[0].checked = true ;
	document.schoolmap.getspan[1].checked = false ;
	document.schoolmap.getspan[2].checked = false ;
	//alert('reloaded');	 // for testing ; 
}
</SCRIPT>

---------------------

<BODY onload="echeck();">

------------------------

   <FORM NAME=schoolmap>
    <input type="radio" checked name="getspan" value="e"
onclick="activate('Elementary');">
	Elementary

	<input type="radio" name="getspan"  value="m"
onclick="activate('Middle');">
	Middle

	<input type="radio" name="getspan"  value="h"
onclick="activate('High');">
	High
	</FORM>
