Hello,
my first question to the experts so please go easy if i post the code wrong!

i am developing a site which has several links that when moused over make some content appear in a div elsewhere on the page. I have it working fine (not tested in IE yet) but i want the content to remain in view when the user mouses out but then be replaced by the new content when a user mouses over another link.

css, javascript and one of the links and its corresponding hidden content below

any help gratefully received!! :)

jon
css:
 
#LinkagesLink {
font-family: Arial, Helvetica, sans-serif;
font-size: 14px;
color: #669900;
width:210px;
height:auto;
float:left;
margin:10 0 0 0px;
text-decoration:none;
 
}
 
#LinkagesLink a {
font-family: Arial, Helvetica, sans-serif;
font-size: 14px;
color: #669900;
width:210px;
height:auto;
float:left;
margin:0 0 0 0px;
text-decoration:none;
 
}
 
#class1 {
position:absolute;
Width:220px;
height:auto;
float:right;
z-index: 2;
visibility: hidden;
}
 
 
 
 
 
 
<script language="JavaScript">
 
function box (boxname,menustate){
 
if (document.getElementById)
{document.getElementById(boxname).style.visibility = menustate;}
 
else {document[boxname].visibility = menustate} }
 
</script>
 
 
 
<div id="LinkagesLink">
<a href="javascript://"onMouseOver="box('class1','visible')" onMouseOut="box('class1','hidden')"><h3>Linkages</h3>
<img border="0" src="../images/buttons/buttonlinkages.jpg"></a>
 
</div>
 
 
 <div id="class1"><h3>Linkages</h3>
	
<p class="newsfeedtext">I have this same menu on a different page and I need whatever link i push on to direct me to this page I have typed above and also have the "magical text" showing depending on which ever link I clicked. Is that clear? Hopefully so!</p></div>

What I've done is sort of re-work your idea from scratch. Let me try to explain why I took this approach.

The basic idea is to show the appropriate element when you mouse over a link and hide the rest (in case another was previously still showing). The easiest way to do that is to simply hide all elements first, and then show the one you want. JavaScript is usually fast enough that you don't even know it happened in that order.

hideAllBoxes() is a function that gets all the DIV elements on the page and loops through them looking for ones that have an ID attribute that starts with "link_". Change this to be whatever you want.

showBox() is a function that shows only the box for the link you are hovering over with your mouse. This is based on the number at the end of "link_", so it just concatenates the number you pass it onto the end, e.g. "link_2".

This should get you started in the right direction. I also highly recommend looking into some of the JavaScript frameworks such as prototype (www.prototypejs.org) and jQuery (www.jquery.com).
<script language="JavaScript">
	function hideAllBoxes() {
		var b = document.getElementsByTagName('DIV');
		for(var i=0;i<b.length;i++) {
			var div = b[i];
			if(div.id.match(/^link_/)) {
				div.style.display = 'none';
			}
		}
	}
	
	function showBox(id) {
		var b = document.getElementById('link_'+id);
		hideAllBoxes();
		b.style.display = '';
	}
</script>
 
<style type="text/css" media="screen">
	div.box { border: 1px solid silver; width: 200px; }
</style>
	
<a href="" onmouseover="showBox(1);">Link 1</a>
|
<a href="" onmouseover="showBox(2);">Link 2</a>
|
<a href="" onmouseover="showBox(3);">Link 3</a>
 
<div id="link_1" style="display:none;" class="box">
	<h3>Link 1</h3>
	<p class="newsfeedtext">This box contains information about Link 1.</p>
</div>
 
<div id="link_2" style="display:none;" class="box">
	<h3>Link 2</h3>
	<p class="newsfeedtext">This box contains information about Link 2.</p>
</div>
 
<div id="link_3" style="display:none;" class="box">
	<h3>Link 3</h3>
	<p class="newsfeedtext">This box contains information about Link 3.</p>
</div>
