Richard,
Thank you for the fast response!
I understand what it does in the sense of what coord it returns, maybe I should
explain the question better.
e.getY() (if triggered on the inside of a layer) gives us the y-coord of the event on
the dynlayer, if triggered on the document, it should be the same as e.getPageY().
e.getPageY() should always return the y-coord of the event on the document.
For example, if a dynlayer's y-position is 100, and the event's y-coord is 10 pixels
within the layer, then e.getY() will return 10, and e.getPageY() will return 110.
Now in a large page (one that has to be scrolled) should this change? I mean, the
e.pageY is still 110 pixels down from the top pf the page.
Subtracting the window.pageYOffset from the e.pageX will result in an incorrect
position on the document.
If we want to get the value of the subtracted offset, shouldn't we create an extra
property of the event to hold this value?
ie:
if (is.ns) {
//x/y-coords
this.x=e.layerX;
this.y=e.layerY;
//pageX/Y-coords
this.pageX=e.pageX;
this.pageY=e.pageY;
//offsetX/Y-coords
this.offsetX=e.pageX-window.pageXOffset;
this.offsetY=e.pageY-window.pageYOffset;
}
NOTE: the way that it currently is in IE, the pageX works how I suggest.
But I am still confused on what it is that we really want here... can anyone please
give me an answer on what is intended here?
Thanks again in advance...
