Change <tr> bg colour through javascript

[bensheard]

Hi
I am trying to change the color of a <tr> background through javascript - ie when the mouse goes over it. How can I do this? I have tried something like this:

<tr id="cell1" onmouseover="darken(1)">
<td>Hello</td>
<td>World</td>
</tr>

<script type="text/javascript">
function darken(id){
var name = "cell" + id;
var cell = document.getElementById(name);
cell.bgcolor = "FFFFFF";
}
</script>

I am pretty sure that I am doing something totally wrong.
Thanks

it is

cell.style.backgroundColor = "#FFFFFF";

Also, since your table bg is already white, this will not show any result...try a different color.
