Show and Hide DIV Layers
May 12, 2005 7:42 AM   Subscribe

What is your favorite method for showing and hiding a DIV layer?

I'm wanting to clean up my site's column content and want clickable/drop-down layers. So it says 'Links' and a user clicks on the 'Links' and the list of links appears underneath.

Extra points for cross-browser, degradable and/or XHTML. Thnx!

div.style.display = (show ? "block" : "none");

or

div.style.visibility = (show ? "visible" : "hidden");

or

if (show) {
  parentNode.appendChild(div);
}
else {
  parentNode.removeChild(div);
}

or

<style>
  .visible { display: block; }
  .invisible { display: none; }
</style>

div.class = (show ? "visible" : "invisible");

Response by poster: (not sure how that fits into an OnClick JavaScript href?)

<html>
<head>
.
.
<style>
div#myToggledDiv {display: none;}
</style>
.
<script type="text/javascript>
function swapMyToggledDiv()
{
if(document.getElementById("myToggledDiv").style.display = "block")
{
document.getElementById("myToggledDiv").style.display = "none";
}
else
{
document.getElementById("myToggledDiv").style.display = "block";
}
</script>
.
.
</head>
<body>
.
.
<div id="myClickyDiv" onClick="swapMyToggledDiv();">clicky stuff happens here</div>
.
.
<div id="myToggledDiv">the display of this is toggled</div>
.
.
</body>
</html>

...is probably the easiest way to do it.

Best answer: Normy's got it. But if can be improved:

<div id="myClickyDiv" onclick="toggleDisplay('myToggledDiv')">

and then you can create a more generic function: 
<script type="text/javascript">
function toggleDisplay(divId) {
  var div = document.getElementById(divId);
  div.style.display = (div.style.display=="block" ? "none" : "block");
}
</script>

Oh, special note, if you are using it in the onclick of an anchor, then be sure to return false else the href will navigate it to the top of the document. e.g.

<a href="#" onclick="someFunc('blah');return false;">show/hide</a>

There's an error in norm's if. It should be: 
if (document.getElementById("myToggledDiv").style.display == "block")
