从C＃code调用JavaScript背后 [英] Invoke JavaScript from C# code behind

问题描述

我想学习asp.net。假设我有这个code：

I am trying to learn asp.net. Assuming that I have this code:

if (command.ExecuteNonQuery() == 0)
    {
       // JavaScript like alert("true");
    }
    else
    {
        // JavaScript like alert("false");
    }

如何，我可以从C＃code后面调用JavaScript？如何做到这一点通过把的JavaScript在脚本这是默认的MS Visual Studio中创建的目录？

How to I can invoke JavaScript from C# code behind? How to do that by putting that JavaScript in Scripts directory which is created by default in MS Visual Studio?

推荐答案

下面是我的方法将时间使用时间从code发送弹出消息后面。我尽量避免这样做 - 但有时我需要

Here is method I will use from time to time to send a pop message from the code behind. I try to avoid having to do this - but sometimes I need to.

private void LoadClientScriptMessage(string message)
{
    StringBuilder script = new StringBuilder();

    script.Append(@"<script language='javascript'>");
    script.Append(@"alert('" + message + "');");
    script.Append(@"</script>");

    Page.ClientScript.RegisterStartupScript(this.GetType(), "messageScript",    script.ToString());
 }
