mozbrowserscrollareachanged 编辑

Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The mozbrowserscrollareachanged event is fired when the available scrolling area in the browser <iframe> changes. This can occur on resize and when the page size changes (while loading for example.)
