[Javascript] An easy one for the experts :-)

Hi,

I have searched the manuals .. on google .. in archives ... without luck.

Consider this piece of code:

<html><head><title>Test</title>
<script>
function position(event)
{
        cursor.style.posLeft=board.style.posLeft+event.x;
        cursor.style.posTop=board.style.posTop+event.y;
}
</script>
</head>
<body>
<p><img id="board" width="320" height="320" src="board.gif" style="position:relative;" onClick="position(event)">
<img id="cursor" src="cursor.gif" style="position:absolute">
</body>
</html>

Purpose:

- whenever a mouse click is detected on board move the cursor to this position.

Problem:

- although the code works (!) the cursor is misaligned.  That is, it is positioned something like 5 pixels to the left of the click and 5 pixels above the click.    I've tried to use pageXOffset and pageYOffset to adjust the cursor - but I guess they're only good when scrollbars are involved.


How do I solve this?   I know I can set position:absolute et al on the board, but this is not acceptable ...

I'm mainly targeting IE but, if at all possible, would like to see a cross-browser solution :-)


Merry Christmas,

Brian
