我一直尝试使用下面的代码来执行，但是消息框没有显示，而且tab也没有关闭。

I have been trying with below code its getting execute but messagebox not displaying and tab also not getting close.

ScriptManager.RegisterStartupScript(this, this.GetType(), "Messagebox", "alert('Record Deleted successfully.Note: This tab is now getting close');", true);

所以我只是从上面的代码中删除'alert'代码，然后执行并关闭选项卡。但是我也想显示通知消息框怎么样？

so i just remove the 'alert' code from above code then its getting execute and getting close the tab. But I also want to display notification message box so how?

ScriptManager.RegisterStartupScript(this, this.GetType(), "Messagebox", "window.close();", true);

推荐答案

试试这个 Try this <script language="JavaScript" type="text/javascript"> window.onbeforeunload = confirmExit; function confirmExit() { return "Are you sure you want to exit this page?"; } </script>

Hi, ScriptManager.RegisterStartupScript(this,GetType(),"showalert","alert('Only alert Message');",true);

参考：Asp使用javascript显示来自代码的警报消息
