怎么在asp.net里先弹出个对话框，按下后再关闭该窗口？

Question

ret = confirm("您真的要关闭该窗口么？");
if (ret)
{
    window.close()
         }

Answer 1

用JAVASCRIPT写javascript:self.close()。

Answer 2

public void OpenNewCloseOld(Page UPage, int heights, int widths, string pagenames, string winnames)
{
StringBuilder SomeScript = new StringBuilder(); 
SomeScript.Append("<script language=javascript>\n");
SomeScript.Append("window.open('"+pagenames+"','_blank','toolbar=no,location=no,directories=no,status=no,menubar=no,scrollbars=yes,resizable=yes,top=0,left=0,height="+heights+",width="+widths+"');" + "\n"); 
SomeScript.Append( "window.focus();window.close();" );
SomeScript.Append("</script>"); 
UPage.RegisterStartupScript("MsgBox", SomeScript.ToString());
}
