The height and width of the form

FF:window.innerWidth and Window.innerhegiht, as well as Document.documentElement.clientWidth and document.documentElement.clientHeight.
General: Document.body.clientWidth and Document.body.clientHeight.
Add Event
IE:element.attachEvent ("onclick", func);.
FF:element.addEventListener ("Click", Func, True).
General: Element.onclick=func. Although you can use the OnClick event, the effect of the onclick and the above two methods is different, and the onclick only executes a process, and attachevent and AddEventListener perform a list of processes, that is, multiple processes. For example: Element.attachevent ("onclick", func1), Element.attachevent ("onclick", Func2) such func1 and FUNC2 will be executed.
Custom Properties for labels
IE: If you define a property value for the tag div1, you can div1.value and div1["value" to get the value.
FF: cannot be taken with Div1.value and div1["value").
Generic: Div1.getattribute ("value").
