李嘉 收藏代码 ① - ASP.NET中实现Javascript信息提示框(版本2)

对于上个版本Javascript信息提示框(版本1)进行了修改, 版本2, 解决了影响页面CSS的问题。

       #region "Javascript信息提示框"
        /// <summary>
        /// js信息提示框
        /// </summary>
        /// <param name="Message">提示信息文字</param>
        /// <param name="ReturnUrl">返回地址</param>
        /// <param name="rq"></param>
        public static void Alert(string Message, string ReturnUrl)
        {
            System.Text.StringBuilder msgScript = new System.Text.StringBuilder();
            msgScript.Append("<script type='text/javascript'> ");
            msgScript.Append("alert("" + FilterJSChars(Message) + ""); ");
            msgScript.Append("location.href='" + ReturnUrl + "'; ");
            msgScript.Append("</script> ");
            System.Web.UI.Page page = (System.Web.UI.Page)System.Web.HttpContext.Current.Handler;
            page.Response.Write(msgScript.ToString());
            page.Response.End();
        }

        /// <summary>
        /// 弹出Alert信息窗
        /// </summary>
        /// <param name="Message">信息内容</param>
        public static void Alert(string Message)
        {
            string AlertScript = string.Format("alert('{0}')", Message);
            AddScripts("Message", AlertScript);
        }

        #endregion

        #region 向页面添加脚本

        public static void AddScripts(string pName,string pScripts)

            page.ClientScript.RegisterStartupScript(page.GetType(), pName, pScripts, true);
        }
