    asp.net中的ALERT、Conform寫法

    在asp.net中使用javascript中alert的三張方法

    string str = "<script language=javascript>alert(驗證碼不正確!);</script>";


    Page.RegisterStartupScript("提示", str);//第一種方法,2005下提示已過時,可以考慮第3、4種方法
    Response.Write(str); //第二種方法,最簡單的方法


    public void Alert(string msg)//第三種方法
      {
    this.ClientScript.RegisterStartupScript(this.GetType(), "alert", "<script language="javascript">alert(" msg ");</script>");
    }



    public void Alert(string name, string msg)//第四種方法
    ...{
    this.ClientScript.RegisterStartupScript(this.GetType(), name, "<script language="javascript">alert(" msg ");</script>");
    }
