推荐答案
如果您提供了卸载功能，它将无法在IE浏览器中使用...
为此，请在"onbeforeunload"中提供该功能，如....
if u give in unload function it will not work in IE browser...
for that give that function in "onbeforeunload" like....
<body onbeforeunload="javascript:alert(''window is closing...'');">
我发现您的代码有两个可能的问题.
我相信如果事件触发时，如果鼠标位于浏览器的客户端窗口之外，则IE返回null.因此，您的条件将评估为false.
另外，如果要通过单击退出"按钮来关闭浏览器，那么<c2>将是一个正值，就像您在0, 0点右侧一样.
I see two possible problems with your code.
I believe that IE returnsnullif the mouse is outside the browser''s client window when the event fires. Your conditional would therefore evaluate tofalse.
Also, if you are closing the browser by clicking on the Exit button, thenwindow.event.clientXwould be a positive value, as you are to the right of the0, 0point.

为此，请尝试以下行.
