javascript sort进行二维数组排序

  var itemlist=[];
   var item={};
   item['id']="1";
   item['phone']=1588288163;
   item['time']=32133;
   itemlist.push(item);
      var item={};
   item['id']="2";
   item['phone']=183288163;
   item['time']=32132;
   itemlist.push(item);
      var item={};
   item['id']="3";
   item['phone']=1585828163;
   item['time']=32143;
   itemlist.push(item);

 

function sortNumber(a, b)
{
return a.time - b.time
}
  

0: {id: "2", phone: [phone], time: 32132}
1: {id: "1", phone: [phone], time: 32133}
2: {id: "3", phone: [phone], time: 32143}

　　这个回调函数就是返回值>0 需要交换 a和b 否则不交换
