I have a table listing a bunch of clients...

I would like a highlight/scroll bar to appear as I move the mouse over each row <TR> tag.

I would guess that it would be simply changing the class of that particular row with the mouseover="". But what would be the best way to do this??

zinc.

You can use CSS:

tr:hover {
background-color: yellow
}

Thank you.

It won't work in IE as it doesn't support :hover on arbitary elements, only on <a> elements.

You will need a bit of DHTML

function setBackColour(obj,colour){
document.getElementById(obj).style.backgroundColor = colour;
}

<td id="test_td" onMouseOver="setBackColour(this.id,'yellow')" onMouseOut="setBackColour(this.id,'')" width="100")>Some Text</td>
