As per following code java script function myfunction() will execute first then the server side button click event.... so u need to add following code in button click event to execute javascript code after server side code..
根据以下代码，java 脚本函数 myfunction() 将首先执行，然后是服务器端按钮单击事件......所以你需要在按钮单击事件中添加以下代码以在服务器端代码之后执行 javascript 代码..
ClientScript.RegisterStartupScript(this.GetType(), "msg", "myfunction();")
ClientScript.RegisterStartupScript(this.GetType(), "msg", "myfunction();")
Following is the code that i have tested and its working.
以下是我测试过的代码及其工作。

C# Code :-
C# 代码：-
protected void Button1_Click(object sender, EventArgs e)
{
Response.Write("In Button Click event");
ClientScript.RegisterStartupScript(this.GetType(), "msg", "<script language=javascript>myfunction();</script>");
}

Place a literal with runat server and fill this literal with the javascript serverside within a stringbuilder
使用 runat server 放置一个文字，并在 stringbuilder 中使用 javascript serverside 填充这个文字
