Help with Drop down/ Overlapping Content

[Grey83]

1) Script Title: Drop down/ Overlapping Content

2) Script URL (on DD): http://www.dynamicdrive.com/dynamici...lapcontent.htm

3) Describe problem:

Hi, ive installed Drop down/ Overlapping Content script and it works very well on ff, but on ie i get this error:

Line: 117
Error: 'null' is null or not an object

Line 117 is:

var subobj=document.getElementById(anchorobj.getAttribute("rel"))

Besides i get also this message in debug window:

'dropdowncontent' is undefined.

Can I solve this problem?

I undestand the problem...

My site is a bulletin board and i've added a php condition to use this script. It's a thing like:

<a href="page.html" <?php  if permission...etc. ?>id="quickslink" rel="quicks"<?php end condition ?>>CLICK</a>

Now the problem is that if user has permissions to use the script anything works ok, otherwise users get that error. Is there a method to solving it?

Inside the .js file, try adding the changes in red below, which checks to see if the drop down DIV actually exists on the page before proceeding to initialize it:

 init:function(anchorid, pos, glidetime, revealbehavior){
		var anchorobj=document.getElementById(anchorid)
		var subobj=document.getElementById(anchorobj.getAttribute("rel"))
		if (!anchorobj || !subobj)
			return

Update: Use this code instead:

 init:function(anchorid, pos, glidetime, revealbehavior){
		var anchorobj=document.getElementById(anchorid)
		if (anchorobj)
			var subobj=document.getElementById(anchorobj.getAttribute("rel"))
		if (!anchorobj || !subobj)
			return
