Window.onresize — the handler invoked when a window is resized

Availability

JavaScript 1.2

Synopsis

<body onresize="handler" ... >
<frameset onresize="handler" ... >
window.onresize

Description

The onresize property of the Window object specifies an event handler function that is invoked when the user changes the size of the window or frame.

The initial value of this property is a function that contains the JavaScript statements specified by the onresize attribute of the HTML <body> or <frameset> tag that defined the window. 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 the Netscape 4 event model, the onresize handler function is passed an Event object as an argument. In the IE event model, no argument is passed, but the applicable Event object is available as the event property of the Window object that contains the element.

In Netscape, the new size of the window is available from the width and height properties of the Event object.
