js 多级对象数组删除对象

let firstIndex = null;
      let secondIndex = null;
      const findItemNested = (arr, itemId, nestingKey) =>
        arr.reduce((a, item, myIndex) => {
          if (a) return a;
          if (item.id === itemId) {
            secondIndex = myIndex;
            return myIndex;
          }
          if (item[nestingKey]) {
            firstIndex = myIndex;
            return findItemNested(item[nestingKey], itemId, nestingKey);
          }
        }, null);
      findItemNested(this.editData.detailList, id, "detailList");
      // 减去父级批次出库数量
      this.editData.detailList[firstIndex].outBatchQuantity -=
        this.editData.detailList[firstIndex].detailList[
          secondIndex
        ].outQuantity;
      // 删除
      this.editData.detailList[firstIndex].detailList.splice(secondIndex, 1);

自己记录下 找到多层detailList里面的某一id进行删除
