IE8: object,object,undefined
FF8.0: undefined,MouseEvent,undefined
Cr16: MouseEvent,MouseEvent,undefined
Opera: MouseEvent,MouseEvent,undefined
Safira: MouseEvent,MouseEvent,undefined
除FF8外，其它瀏覽器都已經支援window.event了
ff8似乎在呼叫事件時with了一個{event:new Event(...)}；所以在onclick裡也可以直接用“event”來擷取事件控制代碼。
另：好奇同學在QWrap的Event裡供了一個QW.EventH.getEvent的靜態方法，用來在各種情況下擷取當前的事件對象，代碼如下： 複製代碼 代碼如下:/**
* 獲得event對象
* @method getEvent
* @param {event} event (Optional)event對象 預設為調用位置所在宿主的event
* @param {element} element (Optional)任意element對象 element對象所在宿主的event
* @return {event} event對象
*/
getEvent: function(event, element) {
if (event) {
return event;
} else if (element) {
if (element.document) {return element.document.parentWindow.event; }
if (element.parentWindow) {return element.parentWindow.event; }
}
if (window.event) {
return window.event;
} else {
var f = arguments.callee;
do {
if (/Event/.test(f.arguments[0])) {return f.arguments[0]; }
} while (f = f.caller);
}
},
所以，使用QW的頁面，可以直接這樣寫： 複製代碼 代碼如下:<a href="#" onclick="EventH.preventDefault()">點我無效</div>
即：調用preventDefault時，不必傳入event執行個體。
