类文件定义了
public static string Alert(string s)
        {
            return "<script language='javascript'>alert(s);</script>";
        }

在aspx页里
  protected void Button1_Click(object sender, EventArgs e)
        {
            
            Response.Write(Class1.Alert("hehe"));
        }
可提示未aspx页里s未定义
为什么?
