Image position

[Fernando Dominguez]

Is it possible to know the absolute position in pixels for one element (image for example) placed on a web page.

I would like to open a layer where the image is clicked. Now I am doing this using the cursor position but. it depens on where is clicked to recalculate the position of the layer.

Is there any property of the image that tells the position.

Thanks.

If you were using a library such as jQuery it would be easy to do, if you are just writing JavaScript yourself, the basic idea is:

function getPosition(theElement){

  var x = 0;
  var y = 0;
              
  while(theElement != null){
    x += theElement.offsetLeft;
    y += theElement.offsetTop;
    theElement = theElement.offsetParent;
  }
                        		      
 return { "x" : x, "y" : y };

}
