Javascript提醒 [英] Javascript alert
问题描述
回发后我需要一个弹出提醒。
1）用户点击提交按钮
2）服务器端代码运行，如果结果是假的我想显示一个java
脚本警报（它不起作用）
如何在显示后显示弹出消息回复？
谢谢

I need a popup alert after a post back.
1) user clicks on the submit button
2) Server side code runs and if the result is false I want to display a java
script alert("It did not work")
How to do I display a popup message after a postback ?
Thank You
Peter
推荐答案
尝试使用
this.Page.ClientScript.RegisterStartupScript
我重新调用它适用于AJAX。

George'的回答是正确的。你有这样的东西......？
protected void MyButton_Click（object sender，System.EventArgs e）
{
bool blnResult =<做服务器端处理> ;;
if（！blnResult）
{
ClientScript.RegisterStartupScript （GetType（），failure，alert（''它
不起作用'）;"，true）;
}
}

George''s response is correct. Do you have something like this...?
protected void MyButton_Click(object sender, System.EventArgs e)
{
bool blnResult = <do server-side processing>;
if (!blnResult)
{
ClientScript.RegisterStartupScript(GetType(), "failure", "alert(''It
did not work'');", true);
}
}
