onmouseover/onmouseout of td elements

I've got a table with some links in it.  Roughly speaking this is:

<table>
<tr><td><a href="...">Link 1</a></td></tr>
<tr><td><a href="...">Link 2</a></td></tr>
</table>

And I define onmouseover and onmouseout events for the table.  When the user mouseovers, it's all fine, but an onmouseout event is triggered if the mouse pointer moves off one of the link elements, even if it doesn't leave the whole table.  How do I avoid this?

put the onmouseover and onmouseout events in the <td> tags...

Hi there,

I solved this by adding a div around the table and defining the mouseover and out on this div, like so:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML>
<HEAD>
<TITLE> over and out </TITLE>
</HEAD>

<BODY>

<div onmouseover="document.getElementById('divStatus').innerHTML = 'over';" onmouseout="document.getElementById('divStatus').innerHTML = 'out';">
<table border="1" cellspacing="0" cellpadding="0">
<tr><td><a href="#">a link</a></tr>
<tr><td><a href="#">another link</a></tr>
</table>
</div>

<div id="divStatus"></div>

</BODY>
</HTML>

Good luck!

Or you could use onmouseenter and onmouseleave in place of the over and out.

I've actually already tried the divs idea.  The fuller version of what I'm dealing with is:

<div onmouseout="window.setTimeout('hideMenu()', 800);" onmouseover="javascript: window.clearTimeout(currentTimeout);" style="display: none; position: absolute; left: 100px; top: 226px;" id="Menu21">
<table cellpadding="0" cellspacing="0" style="background-color: blue; color: white; width: 100px">
<tr><td><a href="/cgi-bin/dynamic/Seniors/Success/371511103.html">Mel's Page</a></td></tr><tr><td><a href="/cgi-bin/dynamic/Seniors/Success/371811103.html">Recent Highlights</a></td></tr></table></div>

hideMenu() hides the menu by setting its display type.  The menu is first shown when you mouseover another div which this one partially overlaps (the idea obviously being that of a pop-up menu).

Expected behaviour is that the menu should pop up when you mouse over the first div and then stay open indefinitely once your mouse is over the menu.

onmouseenter and onmouseleave don't comply with the DOM so can't be used.

what type of menu are you trying to do?

here is one i ran across it may be what you want

Ok, I've basically followed jaysolomon's approach, namely I've removed the tables.  So now we have:

<div>
<a>Link 1</a><br>
<a>Link 2</a><br>
</div>

With onmouseover/onmouseout stuff attached to the div tags and style information specifying the size of the div.

The onmouseout event is still triggered when moving off one of the links though!
jaysolomonCommented:
i have encountered this before, i cannot remember what i did or even if i did. i may have just quit fooling with it.

I will attempt this right now and see what i can come up with
jaysolomonCommented:
i think you will have to have CSS and use absolute position and some z-index

to make this work also
mrh30Author Commented:
I've been working on an idea I found:

Basically you have two divs, with the same position and size.  One contains the links etc, the other is transparent and has the onmouseover events etc attached to it.  Think I'm making some progress.
mrh30Author Commented:
Right finally sorted it out (answering my own question!).

What was happening was that the onmouseout event from the anchors was propagating upwards to the div and triggering its onmouseout event.  Consequently this just needed to be canceled, with a function like:

function stopProp(event) {
      if (document.all) {
            window.event.cancelBubble = true;
      } else {
            event.stopPropagation();
      }
}

attached to the onmouseout event of the anchors.
