[OpenLayers-Users] potential big IE performance enhancement- help!

Tue May 18 13:21:41 EDT 2010

That actually seems a bit slower :(
2:59- to render my layer setting node.style.display="none"; then
node.style.display=""; 
2:42- the original way

I don't understand why setting node.style.cssText is different than
node.style.  Can you explain it briefly?  I ask because the simple example
below seems to work as I'd expect VML.js:setStyle to work.

Thanks again!
Ashley

<html>
<body>
   <div
style="left:50px;top:50px;width:800px;height:600px;background-color:gray;">
   </div>
   <div id="target"
style="position:absolute;width:5px;height:5px;left:100px;top:75px;background-color:red;"></div>
<script type="text/javascript">
   var t = document.getElementById("target");
   var top = 300;
   var left = 400;
   setInterval(move, 750);
   function move() {
       top=Math.floor(Math.random()*600);
       left=Math.floor(Math.random()*800);

t.style.cssText="position:absolute;width:5px;height:5px;background-color:red;top:"
+ top + "px;left:" + left + "px;";
   }
</script>
</body>
</html>
