If you know where the circle "should" be, you can use trigonometry to see if the click is within the circle: http://jsfiddle.net/Vv6Eb/19/

$("div").click(function(e){
    var $me = $(this),
        width = $me.outerWidth(),
        height = $me.outerHeight(),
        top = $me.position().top,
        left = $me.position().left;

    var len = Math.sqrt(Math.pow(width - e.offsetX, 2) + Math.pow(e.offsetY, 2));

    if (len < 10)
        alert('ding');
});​
