Bypass IE “The webpage you are viewing…” pop up

问题

Is there a way to bypass the following IE popup box:

The webapge you are viewing is trying to close the window. Do you want to close this window? Yes|No

This is occurring when I add window.close() to the onclick event of an asp.net button control.

回答1:

Your JavaScript code can only close a window without confirmation that was previously opened by window.open(). This is an intentional security precaution because a script running on a webpage does not own the window, and by closing it discards the browsing history in that window.

The workaround is to either have a "welcome page" or otherwise some sort of page that pops up the window you want to close with window.open in the first place, or to tell your users to modify their browser security settings to allow your application to close their windows.

In the opened popup write following

var objWin = window.self;
objWin.open('','_self','');
objWin.close();

There is a hack for this.

for IE call:

window.open('close.html', '_self');

then in close.html all you need is:

<script>window.close();</script>

Since this essentially opens a popup, in the same named window, when the "new' window opens, it has an "opener" and thus is allowed to close.
