.Net后台弹出脚提示-注册本的两种方法

方法一：

        /// <summary>
        /// 显示Alert提示信息
        /// </summary>
        /// <param name="_strMessage"></param>
        public void ShowAlert(string _strMessage)
        {
            ScriptStartup("alert('" + _strMessage.Replace("\r", @"\r").Replace("\n", @"\n").Replace("'", "\"") + "');");
        }

        /// <summary>
        /// 写客户端脚本(RegisterStartupScript)
        /// </summary>
        /// <param name="_scriptContent"></param>
        public void ScriptStartup(string _scriptContent)
        {
            ClientScript.RegisterStartupScript(this.GetType(), Guid.NewGuid().ToString(), "<script language='javascript'>" + _scriptContent + "</script>");
        }

        /// <summary>
        /// 写客户端脚本(RegisterStartupScript)
        /// </summary>
        /// <param name="_scriptContent"></param>
        public void ScriptStartupMsg(string msg)
        {
            ClientScript.RegisterStartupScript(this.GetType(), Guid.NewGuid().ToString(), "alert('" + msg + "');", true);
        }

    ShowAlert("你要弹出的消息");//调用

方法二：

    public void RegisterScript(string script, bool isAfter)
        {
            if (isAfter)
                ClientScript.RegisterStartupScript(typeof(System.Web.UI.Page), Guid.NewGuid().ToString(), script, true);
            else
                ClientScript.RegisterClientScriptBlock(typeof(System.Web.UI.Page), Guid.NewGuid().ToString(), script, true);
        }

    RegisterScript("你要弹出的消息", true);
