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
