出现这种情况可以是加载顺序的问题，加载没有完成就是显示数据了

试试  async和await

 async beforeOpen(done, type) {
      if (["edit", "view"].includes(type)) {
        await getDetail(this.form.id).then((res) => {
          this.form = res.data.data;
          console.log(this.form);
          this.form.chargingPeriodSetting = this.form.voList;
          console.log(this.form.chargingPeriodSetting)
        });
      }
      done();
    },

改成这种就行了
