只需添加到您的Page_Load事件处理程序，改变的JavaScript字符串到要发生什么。

Just add this to your Page_Load event handler, changing the javaScript string to what you want to happen.

string scriptKey = "OnSubmitScript";
string javaScript = "alert('RegisterOnSubmitStatement fired');";
this.ClientScript.RegisterOnSubmitStatement(this.GetType(), scriptKey, javaScript);
