[Dynapi-Dev] Freeing Memory in IE

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

I have recently found very interesting behavior in IE 5. I used proprietary
code so I don't know about IE4 and NN4 but I will check soon. I used code to
create many DynLayers (520) inside another dynlayer(myLayer). Then I called
document.body.removeChild(myLayer) the memory didn't budge. Then I minimized
and maximized the browser. Walla! from 13MB to 1MB. (This with the Loop to
nullify the DynLayers for they are still there taking up memory).
Here is the code to test:

====================================
<html>
<head>
<title>DynAPI Distribution: Destroy</title>
<script language="Javascript" src="../src/dynapi.js"></script>
<script language="Javascript">
DynAPI.setLibraryPath('../src/lib/');
DynAPI.include('dynapi.api.*');
</script>
<script language="Javascript">
var mLayer;
var a = [];
function dowork(){
for(var i=0;i<101;i++){
a[i] = null;
}
document.body.removeChild(mLayer.elm);

}
DynAPI.onLoad = function() {
	mLayer = new DynLayer();
	mLayer.setHTML("testing memory free in IE");
	DynAPI.document.addChild(mLayer);
	window.status = "ready for action";
for(var i=0;i<521;i++){
a[i] = new DynLayer();
mLayer.addChild(a[i]);
}
}

</script>
</head>

<body bgcolor="#ffffff">

</body>
