进度参考代码

   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);
