JQuery :: Select A Hyperlink With A Specific Name/id?

I have an imagemap with a list of links to one side. The links highlight areas on the map by overlaying a PNG file, and the links need a "selected" state. The areas on the map need to be clickable too, and when these are clicked, the corresponding link item should get the "selected" state. I've got theselected state workingworking when the user clicks on the links, but can't get it working when they click on the map area.

$(document).ready(function(){
$('a.mapnav').click(function () {
var divname= this.name;

[code]....

I checked that "linkname" contains the right text by displaying the label, and it does. All I need to know is how to select the relevant link and add the "selected" class when the imagemap area is clicked.
