Firefox Javascript Href issue

The attached code works fine in all browsers besides Firefox 3.

The idea behind the code is that when a user hovers over the any links in the cateogry_id div, then instead of seeing the full link say ( http://www.google.com/search?q=question1  ) for question 1, they would see , http://www.google.com.

Can anyone noticed why this does not work in FF? I have tested in IE/Chrome/Safari and they all work correctly.

Any assistance would be greatly appreciated.
<script>

	function attach(o, evt, fnc)

	{ 

		 var xMoz= (typeof document.implementation != 'undefined') && (typeof document.implementation.createDocument != 'undefined') && (typeof HTMLDocument!='undefined');

		 var xSaf= navigator.userAgent.toLowerCase().indexOf("safari") != -1;

		 var fIE = !xMoz && !xSaf;

		 if (!fIE)

		 { if (evt.substr(0,2).toLowerCase() == "on") evt = evt.substr(2);

		  o.addEventListener(evt, fnc, false); // Hook the actual event  

		 }

		 else o.attachEvent(evt, fnc);

	}

	function hidehref(ul) {

	   	var li_arr = ul.getElementsByTagName('li'); 

	   	var a_arr = ul.getElementsByTagName('a'); 

	       

	       function hide(e) {  

			var el = (window.event) ? event.srcElement : e.target; 

	        while (el.tagName.toLowerCase() != 'a') { el = el.parentNode;}

	        el.href = "http://www.google.com"; 

	       	return false;

	       }

	       

	       function restore(e) {

	           var el = (window.event) ? event.srcElement : e.target; while (el.tagName.toLowerCase() != 'a') { el = el.parentNode; }

	           var input = el.parentNode.getElementsByTagName('input')[0]; el.href = input.getAttribute('href');

	   	}

	   	

	    for (var i = 0; i < li_arr.length; i++) {

	        if (a_arr[i]) {

	            var input = document.createElement('input');

	            input.type = 'hidden';

	            input.setAttribute('href', a_arr[i].href);

	            li_arr[i].appendChild(input);

	            attach(a_arr[i], "onmouseover", hide);

	            attach(a_arr[i], "onmouseout", restore);

	            attach(a_arr[i], "onclick", restore);

	            attach(a_arr[i], "oncontextmenu", restore);

	        } 

	    }

	}

hey,

try something like the code below.
I think you can't do document.getelementbyid from a function call in firefox?

i think this should work.

Let me know.

        function attach(o, evt, fnc)

                 var xSaf= navigator.userAgent.toLowerCase().indexOf("safari") != -1;

                 var fIE = !xMoz && !xSaf;

                 if (!fIE)

Hi JohnBobH,

That did not work. It still results in the same issue only in FF.

Any other ideas?

Cheers.

Problem seems to be like that Firefox fetch the url to be displayed in status bar before you alter it at onmouseover event.

I found a similar solution what work on FF on http://roshanbh.com.np/2008/08/different-status-bar-text-hyperlink-mouseover.html, But in there we can't have the actual url on href which is not seo friendly.
