Hi,
How can I change the bg color of a table td by javascript? The color is a variable.
e.g.
<head>
<script>
color1="#FF0000";
</script>
</head>
<body>
<table>
<tr>
<td onMouseOver='this.bgColor=color1'>AAA</td>
<td>BBB</td>
</tr>
</table>
</body>
However, I want the color be set when the page is loaded, but not after the mouse events.
Thank you very much.

Sorry "coloradd row" unnecessary. It's mistake ;)

Thanks, Dennis.
However, in this way, do I need to move all my html tags into "document.write();" statements ?
I want to minimize the modification on my html file...

O, I got it now. Just move the line of document.wirte() inside the <tr></tr>... Thanks.

Give the desired cell an id name (<TD id="ACELL">xxx</td>
Then, in the javascript, in whatever event you desire (I think you
want it in the onload event in the <BODY> tag) have a line
document.all.ACELL.style.backgroundColor = varColor, where varColor
is your variable color

Why not document.getElementById('ACELL').style.backgroundC olor =
so that it works in other browsers as well?

My code doesn't recognize any other browsers :) Our systems
assume IE only, so all my answers will too. I should specify that.
Thanks for the additional accuracy.

This is invalid HTML. The "script" element misses a "type" attribute
(with the value "text/javascript") and the element it must not occur
as child of "table" or "thead", "tbody", "tfoot" or "tr". Do that
server-side. Anything else is considered harmful.
As for the onmouse* event handlers, this is inefficient, unless only
one table cell is going to be highlighted. I think I have posted a
combination of CSS td:hover and an event listener for the parent "table"
element here previously.
