Sets or retrieves the x-coordinate of the mouse pointer's position relative to the client area of the window, excluding window decorations and scroll bars.

specifies or receives the x-coordinate, in pixels.|
The property is read/write.
The property has no default value.
Expressions can be used in place of the preceding value(s), as of Microsoft® Internet Explorer 5. For more information, see About Dynamic Properties.
The property is read-only in Microsoft® Internet Explorer 4.0, and read/write in Internet Explorer 5 and later.
Because the clientX property returns a value relative to the client, you can add the value of the scrollLeft property to determine the distance of the x-coordinate from the edge of the body element.
Within a viewlink, the client area begins at the edge of the master element.
This example uses the clientX property to determine the mouse position relative to the window. The status window shows the mouse position at all times.
var offsetInfo = ""
clientInfo = "The x coordinate is: " + window.event.clientX + "\r"
clientInfo += "The y coordinate is: " + window.event.clientY + "\r"
<BODY onmousemove="window.status = 'X=' + window.event.clientX +
' Y=' + window.event.clientY"
