Move the mouse over the document. |
| Default action |
Initiates any action associated with this event. |
A mousemove event occurs when the pointing device is moved while it is over an element. This event is valid for most elements.
While event handlers in the Document Object Model do not receive parameters directly, the handler can query the event object for data.

The following sample demonstrates the use of the onmousemove event to monitor the location of the mouse cursor on the screen.
When the mouse cursor moves over the DIV object, a SPAN object is updated with the clientX and clientY property values. The clientX and clientY properties are exposed by the event object.
