clientX Event AttributeEvent Object
Definition and Usage
The clientX event attribute returns the horizontal coordinate (according to the client area) of the mouse pointer when an event was triggered.
The client area is the current window.
The following example alerts the coordinates of the mouse pointer when the mouse button was clicked:
alert("X coords: " + x + ", Y coords: " + y)
<p onmousedown="show_coords(event)">Click this paragraph, and an alert box will alert the x and y coordinates of the mouse pointer.</p>
