How change image map area element style

I'm using image map on my web page and iPad app. Each area on the image map is a clickable element to make sound, which I can do easily with jQuery. But I haven't been able to change the style, like either showing the border, or change the fill color just to indicate that the area is clic开发者_StackOverflow社区ked. If anybody has done this, please let me know; it seems simple, but I'm really stumped.

I got it to work thanks to James Treworgy's awesome ImageMaster Jquery plugin.

$('area').mousedown(function(e) {
   $(this).mapster('set',true);
});

$('area').mouseup(function(e) {
   $(this).mapster('set',false);
});

$('area').bind( "touchstart", function(e){
   $(this).mapster('set',true);
});

$('area').bind( "touchend", function(e){
   $(this).mapster('set',false);
});

It's hard to say without seeing the code, but the same way you are referencing the parts of the map is the same way you apply the styles.

If you have a section1 id, then you css could be

#section1{
    border://something
    background-color://something else
}

Or, in your script, when you reference the click, you also add some styles, e.g.,

$('#section1').click(function(){
    //whatever
    $(this).css({'background-color' : 'red', 'border' : '1px solid black'});
});
