clientX Property

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

Syntax

HTMLN/A
Scripting[ iXPos = ] event.clientX

Possible Values

iXPosInteger that specifies the x-coordinate, in pixels.

The property is read-only with no default value.

Remarks

Since the clientX property returns a value relative to the client, you can add the value of the scrollLeft property to determine the distance from the edge of the BODY element.

Example

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.

Sample Code

<SCRIPT>
function clientCoords()
{
    var offsetInfo = ""
    clientInfo = "The x coordinate is: " + window.event.clientX + "\r"
    clientInfo += "The y coordinate is: " + window.event.clientY + "\r"
    alert(clientInfo);
}
</SCRIPT>
</HEAD>
<BODY onmousemove="window.status = 'X=' + window.event.clientX +
    ' Y=' + window.event.clientY"
    ondblclick="clientCoords()">
