Name

HTMLElement.onmouseover — the handler invoked when the mouse moves over an element

Availability

JavaScript 1.2; HTML 4.0

Synopsis

<element onmouseover="handler" ... > element.onmouseover

Description

The onmouseover property of an HTMLElement object specifies an event handler function that is invoked when the user moves the mouse pointer over the element.

The initial value of this property is a function that contains the JavaScript statements specified by the onmouseover attribute of the HTML tag that defined the object. When an event handler function is defined by an HTML attribute, it is executed in the scope of element rather than in the scope of the containing window.

In Netscape 4, the onmouseover handler function is passed an Event object as an argument. In IE 4, no argument is passed, but the applicable Event object is available as the event property of the Window object that contains the element.
