In Javascript, within the Javascript event handler for onMouseMove how do I get the mouse position in x, y coordinates relative to the top of the page?
if you can use jQuery, then this will help:
<div id="divA" style="width:100px;height:100px;clear:both;"></div>
<span></span><span></span>
<script>
$("#divA").mousemove(function(e){
var pageCoords = "( " + e.pageX + ", " + e.pageY + " )";
var clientCoords = "( " + e.clientX + ", " + e.clientY + " )";
$("span:first").text("( e.pageX, e.pageY ) - " + pageCoords);
$("span:last").text("( e.clientX, e.clientY ) - " + clientCoords);
});
</script>
here is pure javascript only example:
var tempX = 0;
var tempY = 0;
function getMouseXY(e) {
if (IE) { // grab the x-y pos.s if browser is IE
tempX = event.clientX + document.body.scrollLeft;
tempY = event.clientY + document.body.scrollTop;
}
else { // grab the x-y pos.s if browser is NS
tempX = e.pageX;
tempY = e.pageY;
}
if (tempX < 0){tempX = 0;}
if (tempY < 0){tempY = 0;}
document.Show.MouseX.value = tempX;//MouseX is textbox
document.Show.MouseY.value = tempY;//MouseY is textbox
return true;
}
