NN4 Section of script not working

3D_Dog_Man · 07-09-2004, 04:06 AM

Hi Everyone,

I have a script that is designed to dynamically position page elements. It is working very well in IE6 and NN7. However I have tried the script in NN4 and it is not working at all. I have not yet had the opportunity to test this script on IE4! Please see the code below, the largely commented section toward the bottom of the script is where the NN4 commands are located. If you can help me with working out what is wrong with the way I have written this script I will be greatly appreciative.

<html>
<title> Simple Element Positioning Script </title>
<head>
<style type="text/css">
#car
{
position: absolute;
}
</style>
<script language="javascript" type="text/javascript">
// 
</script>
</head>
<body>
<img id="car" src="car.jpg">
<script type="text/javascript">
posElem('car', 100, 100);
</script>
</body>
</html>

Also if you can see anything wrong with the way the IE4 section is coded can you please point it out, as I am not in a position to check this section (I don't have IE4 - I guess not many people do). Thanks heaps for your assistance.

Regards

Davo

Put the image inside the div tag and move the id there.

<div id="car"><img src="car.jpg" /></div>

and then use the original code:

document.layers[elementID].left = xPos;
document.layers[elementID].top = yPos;

Another idea: Don't call posElem() in the body, call it in the onload event handler.

element = document.all[elementID];

In NN4 if the positioned element is contained by another positioned element then you have to recurse thru document.layers[id].document.layers[id] etc. For example:

Code:

function xGetElementById(e) {
  if(typeof(e)!='string') return e;
  if(document.getElementById) e=document.getElementById(e);
  else if(document.all) e=document.all[e];
  else if(document.layers) e=xLayer(e);
  else e=null;
  return e;
}
function xLayer(id,root) {
  var i,layer,found=null;
  if (!root) root=window;
  for(i=0; i<root.document.layers.length; i++) {
    layer=root.document.layers[i];
    if(layer.id==id) return layer;
    if(layer.document.layers.length) found=xLayer(id,layer);
    if(found) return found;
  }
  return null;
}

BTW, its almost sacrilegious to be discussing NN4 in the DOM forum ;-) LOL!
