避免关闭窗口时,弹出"关闭"提示窗口-

一.关闭本窗口

1var hwnd = window.open("about:blank","_self");//logout.aspx?
2if (hwnd==null)
3    alert('请关闭弹出窗口拦截功能');
4else
5    hwnd.close();
6 

二.从本窗口打开一个全屏窗口，然后再关闭原窗口

 1            var hwnd = window.open("Default_main.aspx","_blank","resizable=yes");//"fullscreen=yes, menubar=no, resizable=no,scrollbars=yes,status=no,titlebar=no,toolbar=no"
 2            if (hwnd==null)
 3            {
 4                alert('请关闭弹出窗口拦截功能');
 5            }
 6            else
 7            {
 8                hwnd.moveTo(0,0);
 9                hwnd.resizeTo(screen.availWidth,screen.availHeight);
