DHTML in Netscape

11-01-2004

I have some DHTML that is showing and hiding a div. This works in IE and
Firefox, but not in Netscape.

<html>
<head>
<script language="javascript">
function switchDisplay()
{
if (myDiv.style.display=='block')
myDiv.style.display='none';
else
myDiv.style.display='block';
}
</script>
</head>
<body>
<form myform. . . >
<myDiv style="display:block">
blah
</myDiv>
<input type="button" value="test me" onclick="javascript:
switchDisplay();">
</form>

</body>
</html>

In the javascript, I can refer to the div directly in IE and Firefox (and
Mozilla). It does nothing in Netscape.

I've tried document.myDiv.style.display,
document.elements['myDiv'].style.display, and trying to walk the DOM through
the form.

Any suggestions would be greatly appreciated.

Thx!

Netscape what? 3 or less? 4.x? or 6 and above?

3 doesn't do "DHTML".
4 is a buggy nightmare with dwindling market hare and not worth worrying
about.
6 should support pretty much anything any other Gecko based browser
supports.

The Language attribute is deprecated, and the type attribute is required.

What is "myDiv"? You need to use document.getElementById (or document.all
for ancient versions of IE, or goodness knows what for Netscape 4) to get
an object reference first.

> <myDiv style="display:block">

There is no "myDiv" element in HTML.

> switchDisplay();">

Loose the "javascript:" bit.

What do you mean by "Netscape"? There are significant differences between,
say, Netscape 4.08 and Netscape 7.1.

Most humble apologies. I'm trying this with Netscape 7.2 The Div is
<div name="myDiv" id="myDiv" style="display:block">

.. . .

</div>

Function should read:

function switchDisplay() {
myDiv = document.getElementById('myDiv');
if (myDiv.style.display=='block') myDiv.style.display='none';
else myDiv.style.display='block';
}

> <div name="myDiv" id="myDiv" style="display:block">
> . . .
> </div>

HTML should read:

<div id="myDiv">...</div>

The other attributes style/name are not needed.

There is no name attribute for div elements. Also, I recommend to never
use the same identifier for name and id attributes.
As mentioned by others, style="display:block" is also pointless as this
is the default display declaration in all CSS-capable browsers.
