You can use the pageX and pageY property of the jQuery event object:

$('#a2').click(function(e) {
    alert(e.pageX + ", " + e.pageY);
});

The returned coordinates are relative to the top left of the document.

You might want to use the A-Tools plugin, more specifically its getSelection() method. It returns the caret position if no text is selected.

By the way, the "text cursor" is called the caret :)

EDIT: The aforementioned plugin will not work with contenteditable <div>elements. While looking for another solution, I found that question which is a duplicate of yours. Maybe the responses there can help you.

you can use Prototype.js to get mouse position:

var x, y;
function getCoordinatesInsideElement(e)
{
    x = Event.pointerX(e);
    y = Event.pointerY(e);
    /* DO-SOMETHING */
}

See prototype reference at: http://api.prototypejs.org/
