C# 后台弹出提示

1. 浏览器弹出提示

Response.Write("<script>alert('失败!')</script>");
return;

 

2. 当前窗口弹出提示，可自动关闭当前窗口

  this.Alert("操作成功！", "CloseFrame(true);");//弹出提示并关闭当前窗口
  //this.Alert("操作成功！"); //弹出提示
  return;

 

3.带有遮罩层，解决使用1刷新之后出现的样式挤压问题，在当前窗口弹出

RegisterScript("st", "setTimeout(function(){if(alert_h){alert_h(\"删除成功！\", null, null, false);}else{alert(\"删除成功！\");}},300);", true);
//setTimeOut(function(){doChk2()}, 1000)
return;

 

1.2 使用引用的方法

        /// <summary>
        /// 弹出提示
        /// </summary>
        /// <param name="messege">提示消息</param>
        public void Alert(string messege, string func = "")
        {
            if (!string.IsNullOrEmpty(func))
            {
                RegisterScript("scriptAlert", "setTimeout(function(){ if(alert_h){alert_h(\"" + messege + "\",function(){$(document.body).removeClass('modal-open');" + func + "});}else{alert(\"" + messege + "\");setTimeout(function () { " + func + " }, 500)}},300);", true);
            }
            else
            {
                RegisterScript("scriptAlert", "setTimeout(function(){ if(alert_h){alert_h(\"" + messege + "\",function(){$(document.body).removeClass('modal-open');});}else{alert(\"" + messege + "\");}},300);", true);
            }
        }
        /// <summary>
        /// 注册客户端脚本块
        /// </summary>
        /// <param name="key">键</param>
        /// <param name="script">脚本</param>
        /// <param name="type">注册的脚本块类型；true为RegisterStartupScript，否则RegisterClientScriptBlock</param>
        public void RegisterScript(string key, string script, bool isStartUp)
        {
            StringBuilder cstext2 = new StringBuilder();
            cstext2.Append("<script type=\"text/javascript\">");
            cstext2.Append(script);
            cstext2.Append("</script>");

            ClientScriptManager scriptManager = this.Page.ClientScript;
            if (!scriptManager.IsClientScriptBlockRegistered(this.GetType(), key))
            {
                if (isStartUp)
                {
                    scriptManager.RegisterStartupScript(this.GetType(), "clientScript_" + key, cstext2.ToString());
                }
                else
                {
                    scriptManager.RegisterClientScriptBlock(this.GetType(), "clientScript_" + key, cstext2.ToString());
                }
            }
        }
