    generate area of map tag and make it different when on mouseenter function

    Hello, i have probleme to generate <area> tags inside <map>, idea is quite simple:
    I would like to take image and divide its map into 12 area depending on picture size(height, width)
    Here is my code (not functional):

    <body onload="load()">
    <img id="img" src="IMAGES SRC" usemap="#map"/>
    <map name="map" id="map"></map>
    <script language='javascript'>
    function load() {
    img = getElementById(img);
    var h2 = img.height/3;
    var w1 = img.widht/4;
    for (var i = 0; i <= 2; i++) {
    var y = i*h2;
    var p = ++i;
    for (var j = 0; j <= 3; j++){
    var x = j * w2;
    var f = ++j;
    el = document.createElement('area');
    el.setAttribute('shape', 'rect');
    el.setAttribute('id', j + i);
    el.setAttribute('coords', x + ',' + y + ',' + f * w2 + ',' + p * h2);
    el.setAttribute('href', j+i +'.html');
    document.getElementById('map').appendChild(el);
    };
    };
    };
    </script>

    Next question is if it is possible to make <area> active when i go with mouse over them.
    THANK YOU for any help
