------ Solution ------------------------------------------- -

  把createtime做为参数传进去就好了
  function dateFormat(time){
          	if(!time){
          		return "";
          	}
          	var tmp = eval(time);
          	var date = new Date();
  			date.setTime(tmp.time);
  			var year = date.getYear();
  			var month = date.getMonth() + 1;
  			var day = date.getDate(); //获取当前日(1-31)
      		/*var hour = date.getHours(); //获取当前小时数(0-23)
      		var minute = date.getMinutes(); //获取当前分钟数(0-59)
      		var second = date.getSeconds(); //获取当前秒数(0-59)*/
      		month=month<10?("0"+month):month;
      		day=day<10?("0"+day):day;
      		/*hour=hour<10?("0"+hour):hour;
      		minute=minute<10?("0"+minute):minute;
      		second=second<10?("0"+second):second;*/
      		var dateStr = year + "-" + month + "-" + day;
      		//dateStr = dateStr + " " + hour + ":" + minute + ":" + second;
      		return dateStr;
          }
