Hey...I'm putting up a new layout for my site, with tables used extremely excessively. I was wondering, how do you make it so that the background color of rows change on mouseover? If someone could help me out, I'd appreciate it. Thanks.

That is simple javascript... so simple I can do it :) YAY!

<tr onMouseOver="this.style.backgroundColor = '#ff0000'" onMouseOut="this.style.backgroundColor = '#ffffff'">
<td>Testing 1..2..3.. Testing</td>

Or you could pass it to a function...I think ;)

var OriginalColor = '#ffffff'
var RollOverColor = '#ff0000'
function changeIt(TheCell){
if (TheCell.style.backgroundColor = OriginalColor) {
TheCell.style.backgroundColor = RollOverColor
TheCell.style.backgroundColor = OriginalColor

Now you can easily do this..

<tr id="MyTr" onMouseOver="changeIt(this.id)" onMouseOut="changeIt(this.id)">
<td>Testing 1..2..3..Testing</td>

Although I'm not sure about the this.id , if that doesn't work then just use the current tr's id which in this case is MyTr.

So it would look like:

onMouseOver="changeIt(MyTr)" onMouseOut="changeIt(MyTr)"

or you could change the class! (my favourite way of doing it)

td.on {
background-color: #999999;
td.off {
background-color: #FFFFFF;

&nbsp;&nbsp;&nbsp;&nbsp;<td onmouseover="this.className='on';" onmouseout="this.className='off';" class="off">

Ahhh! className... Finnaly! I've been trying to do that for ages. I should of asked but for some reason I just forgot about it.

In the end I settled for changing the style in the javascript itself which is not an esaily editable way of doing it.

Thanks for that redhead! :D

Sorry it took me a day or two or whatever (no concept of time) to reply, but I've been doing alot of last-minute Christmas shopping. Anyway, in response to your question, M, I used your first example - the one that just used MouseOver and MouseOut. Thanks for it. I'll try the class setting in a minute, red.

Which browsers actually support events on td elements these days?

sheesh kabab... loads of them...

ie 4+, mozilla, ns6+ (if not 5+), definatly opera 6.05 (probably some of the earlier opera's too) etc... so pretty much everyone (depending on javascript being enabled ;)) will be able to see it...
