setInterval循环设置并传入不同的参数

 1 var taskId;
 2     var __sto = setInterval;     
 3     window.setInterval = function(callback,timeout,param){     
 4      var args = Array.prototype.slice.call(arguments,2);     
 5      var _cb = function(){     
 6          callback.apply(null,args);     
 7      }     
 8      intervalTime[taskId]= __sto(_cb,timeout);     
 9    }
10 
11     for(var i=0;i<taskIds.length;i++){    
12         taskId=taskIds[i];
13       window.setInterval(CheckProgress,100,taskIds[i]);
