Dear everyone,

First of all, I am a newbie to html and javascript (ie. never used them before) so please bear with me.

I am trying to capture the x and y coordinate of the left mouse click and save them to a file. While browsing the internet i found the following code,

<script type="text/javascript">
document.onmousedown = function(e){
var coordX = (e && e.pageX)? e.pageX : event.x;
var coordY = (e && e.pageY)? e.pageY : event.y;
alert('x = '+coordX+'\ny = '+coordY);
}
</script>

This however does not serve my purpose:
1- It does not save the x and y coordinates into a file but rather displays them within a dialog box.
2- User scrolling is ignored. I want to capture the x and y coordinates in relation to the top right corner of the document. (that is, the invisible parts of the screen once the user scrolls must be taken into consideration)

Can someone please help ?
