Mouse position over tabled canvas

Postby misterwoo » Wed Mar 23, 2011 2:34 am

Hi,
I have an HTML canvas in a html table. Depending on the size of the browser the mouseover position (when hovering over the canvas) changes. I would like to be able to find out the offset of the canvas. Is there an element in the mouseover event that I can look at?

I tried susbtracting pageY and pageX with no success.

function handleMouseover(e) {
var posx = e.clientX;
var posy = e.clientY;
var text = posx+";"+posy;

posx=e.screenX-e.pageX;
posy=e.screenY-e.pageY;
text = posx+"/"+posy;
drawEventDisplay(text);

Maybe you want canvas.offsetTop and canvas.offsetLeft?
