Complete Event Object Reference

Definition and Usage

The clientY event attribute returns the vertical coordinate (according to the client area) of the mouse pointer when an event was triggered.

The client area is the current window.

Syntax

event.clientY

Example

The following example alerts the coordinates of the mouse pointer when the mouse button was clicked:

<html>
<head>
<script type="text/javascript">
function show_coords(event)
  {
  x=event.clientX
  y=event.clientY
  alert("X coords: " + x + ", Y coords: " + y)
  }
</script>
</head>

<body onmousedown="show_coords(event)">

<p>Click in the document. An alert box will alert 
the x and y coordinates of the mouse pointer.</p>

</body>
</html>
