C＃WebBrowser-作用于javascript window.close（）; （act =覆盖关闭WinForm窗口）

Question

I have an web application containing a javascript block which wants to close the opened window. This is done by window.close();

I'm hosting this application in a C# WebBrowser WinForm project. When the javascript code window.close(); gets called, I'm getting a MessageBox question from the WebBrowser. This says 'The Webpage is trying to close the window...'. If clicked yes, the WinForm window will close.

My issue is that I would like to allow javascript to close this window, I don't want this warning message to appear.

Any ideas? I've tried overriding WinForm FormClosing event , but this message happens directly in the WebBrowser. I have also overrided WndProc in WM_PARENTNOTIFY (0x210), on WM_DESTROY . However this is called after the question is answered in the WebBrowser warning.

Adding these for window closing in javascript works great:

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