按对象里面某个key值排序

 //分类标签页数据按key大小排序处理
  compare = (property)=>{
    return function(a,b){
      let value1 = a[property];
      let value2 = b[property];
      return value1 - value2;
    };
  };

 testF1 = (data) =>{
    let Arr = [];
    data.sort(this.compare('key')).map((i,j)=>{
      let item = {};
      item.imgUrl = card1Data1[parseInt(i.key)-1].imgUrl;
      item.title = i.title;
      item.key = i.key;
      Arr.push(item);
    });
    return Arr;
  };
