1>獲取控件用document.getElementById，不用document.all（FF等瀏覽器不支持）
2><button> 會(huì)被firefox解釋為提交form或者刷新頁(yè)面,需要寫標(biāo)準(zhǔn)<button type="button">
3>使用childNode()代替之前的children?
4> 手型鼠標(biāo)指針請(qǐng)用cursor:pointer，不用 cursor:hand
5>獲取自己定義的屬性 用? document.getElementByID("TD1").getAttribute("isOBJ")? 代替document.getElementByID("TD1").isOBJ
6>事件追加方法attachEvent(IE)/detachEvent;addEventListener( Mozilla, Netscape, Firefox)/removeEventListener
? 又或者直接用obj.onmouseover=func;
7>Firefox中不存在 Event時(shí)間,必須通過(guò)object本身去取
?? 在Firefox獲取當(dāng)前物件的坐標(biāo)方法：
? document.onmousemove = Inti_move;
? function? Inti_move(ert)
{
? x=ert.pageX;
}

Internet Explorer Name Mozilla Name Description 表4 Mozilla與IE之間的事件屬性差異

altKey	altKey	Boolean property that returns whether the alt key was pressed during the event.
cancelBubble	stopPropagation()	Used to stop the event from bubbling farther up the tree.
clientX	clientX	The X coordinate of the event, in relation to the element viewport.
clientY	clientY	The Y coordinate of the event, in relation to the element viewport.
ctrlKey	ctrlKey	Boolean property that returns whether the Ctrl key was pressed during the event.
fromElement	relatedTarget	For mouse events, this is the element from which the mouse moved away.
keyCode	keyCode	For keyboard events, this is a number representing the key that was pressed. It is 0 for mouse events.
returnValue	preventDefault()	Used to prevent the event's default action from occurring.
screenX	screenX	The X coordinate of the event, in relation to the screen.
screenY	screenY	The Y coordinate of the event, in relation to the screen.
shiftKey	shiftKey	Boolean property that returns whether the Shift key was pressed during the event.
srcElement	target	The element to which the event was originally dispatched.
toElement	currentTarget	For mouse events, this is the element to which the mouse moved.
type	type	Returns the name of the event.

8>event.keyCode的問(wèn)題解決
在FF中不存在window.event.keyCode屬性。可以用以下方法解決

function ?keepKeyNum(evt)
{
? var ??k = window.event ? evt.keyCode:evt.which;
????? if ?((k <= 57 )? && ?(k >= 48 ))
{ return ? true ;}
????? else ?
{ return ? false ;}

? < input? type ="text" ?onKeyPress ="?return?keepKeyNum(event);" ? >

javascript IE與FireFox 一些兼容寫法
