js根据对象值排序

// 根据对象值排序
objectSort(myobj) {
  // 获取属性值并按从大到小排序
  let newArray = Object.values(myobj)
  newArray.splice(10, 1)
  let result = newArray.sort((a, b) => {
    return b - a;
  });
  let new_obj = [];
  for (let i = 0; i < result.length; i++) {
    // 将原对象中的键值对按照属性值的排序顺序写入新对象
    Object.keys(myobj).map((item, index) => {
      if (item === "num" || new_obj.length >= this.placesVal) {
        return
      }
      if (myobj[item] === result[i]) {
        item = Number(item)
        if (new_obj.length >= this.placesVal) {
          this.invertChooseArr.push(item)
        } else {
          if (!new_obj.includes(item)) {
            new_obj.push(item)
          }
        }
      }
    });
  }
  return new_obj
},
