MozScrolledAreaChanged Redirect 1

The MozScrolledAreaChanged event is fired when the document view has been scrolled or resized.

Note: While you can poll the values of document.scrollWidth and document.scrollHeight to watch for changes to the document size, reading these properties can trigger document reflow, which can make them computationally expensive. This event, introduced in Gecko 1.9.2, is fired whenever either or both of these values change.
