More comprehensive event-like differences in IE and FF recommended _javascript tips

Window.event
IE: There are window.event objects
FF: No Window.event object. You can pass an event object to a parameter of a function. such as Onmousemove=domousemove (event)
Mouse Current coordinates
Ie:event.x and Event.y.
FF:event.pageX and Event.pagey.
General: Both have Event.clientx and Event.clienty attributes.

The current coordinates of the mouse (plus the distance the scroll bar rolls over)
IE:event.offsetX and Event.offsety.
FF:event.layerX and Event.layery.
Coordinates of the x and Y of the label: Style.posleft and Style.postop
IE: there is.
FF: No.
General: Object.offsetleft and Object.offsettop.

Height and width of the form
IE:document.body.offsetWidth and Document.body.offsetHeight. Note: The page must have a body tag at this point.
FF:window.innerWidth and Window.innerhegiht, as well as Document.documentElement.clientWidth and document.documentElement.clientHeight.
General: Document.body.clientWidth and Document.body.clientHeight.

Adding events
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 not the same, onclick only executes a process, and attachevent and AddEventListener execute a list of processes, that is, multiple processes. For example: Element.attachevent ("onclick", func1), Element.attachevent ("onclick", Func2) so func1 and Func2 will be executed.

Custom Properties for labels
IE: If a property value is defined for the label DIV1, the value can be obtained Div1.value and div1["value".
FF: cannot be taken with Div1.value and div1["value".
General: Div1.getattribute ("value").

Parent node, child node, and delete node
Ie:parentelement, Parement.children,element.romovenode (true).
Ff:parentnode, Parentnode.childnodes,node.parentnode.removechild (node).
