image map rollover background color chg

Is there a combination of javascript/css that take the value given in an image map onmouseover/onmouseout and go to an href list and change the href class? (Basically, I want to change the background color as a highlighted selection, but the list below the image map also needs to be clickable.)

for example:

<img src='images/mapP2.gif' border='0' usemap='#Map'>
<map name='Map'
<area shape='rect' coords="1,20,5,40" href='http://something' onMouseOver="9.className='home'" onMouseOut="9.className='home3'">
</map>

When the above occurs, the following is changed?

<div id='9'><a class='home3' href='http://something'>My link to change class</a></div>

Thanks,
JB
