View Full Version : Help Needed with toggle

12-20-2006, 08:32 AM
I need help from a javascript expert. I need to be able to toggle between selections form a select box. But it can only show one at a time, and hide the current one if a new one is selected. I came up with this code below. But it will not hide the current div, once a new div is selected. It will simply show both. Can anyone help me out with this?

<script type="text/javascript">
function toggleLayer(whichLayer)
if (document.getElementById)
// this is the way the standards work
var style2 = document.getElementById(whichLayer).style;
style2.display = style2.display? "":"block";
else if (document.all)
// this is the way old msie versions work
var style2 = document.all[whichLayer].style;
style2.display = style2.display? "":"block";
else if (document.layers)
// this is the way nn4 works
var style2 = document.layers[whichLayer].style;
style2.display = style2.display? "":"block";

<FORM NAME="myform">
<SELECT NAME="mylist" onChange="toggleLayer(document.myform.mylist.value)">

<div id="m1" style="display: none">
this is stuff M1</div>
<div id="m2" style="display: none">
this is stuff M2</div>
<div id="m3" style="display: none">
this is stuff M3</div>

Thank you for any assistance you can offer to me!

You're welcome. I would appreciate being addressed by my name. It's people who post code here for others, not machines, agree?

Good luck with the remainder of your project.
