You can pull it right out of this:

$(selector).click(function() {
    var id = this.id;
    // Do interesting things.
});

The this in a jQuery click callback is just a DOM object that exposes its attributes as object properties.

You can use the this key word:

$(".elementClass").click(function () {
   var currentElement = $(this); // refers to the current element

   var theId = currentElement.attr("id");
});
