进度参考代码

Posted 2020-06-17

   1.按钮点击的时候开始监视进度
   var interval = window.setInterval(GlobalControlProcess, 1500);   
   2.js调用一般处理程序轮询进度
   function GlobalControlProcess(){
           $.post("/Common/ComputeProcess.ashx", {ComputeType:"rsk_pro"},function(data){
              data=JSON.parse(data);
              if (data.state.toString() == "7") {
              SetCompleted();
              window.clearInterval(interval);
             }
             else{
             SetPorgressBar(Math.ceil(parseInt(data.state)/7*100));
             $("#p"+data.state.toString()).fadeIn("slow");
             }
           });

 3.进度完成后清除计时器
  window.clearInterval(interval);

4.一般处理程序代码

        {
            context.Response.ContentType = "text/plain";
            //context.Response.ContentType = "application/json";
            context.Response.Cache.SetCacheability(HttpCacheability.NoCache);
            if (context.Request["ComputeType"]!=null&&!string.IsNullOrEmpty(context.Request["ComputeType"]))
            {
                string computeType = context.Request["ComputeType"];
                if (HttpContext.Current.Session[computeType] == null)
                {
                    HttpContext.Current.Session.Add(computeType,1);
                }
                var obj = new {state = HttpContext.Current.Session[computeType.ToString()]};
                context.Response.Write(Newtonsoft.Json.JsonConvert.SerializeObject(obj));
                context.Response.End();

            }
        }

        {
            get
            {
                return false;
            }
        }
    }
