vue 路由参数变化，页面不更新的问题

监控$route

<script>
export default {
    data() {
        return {
            setMealId: 0,
            setMealTypes: [
                {type: ‘A‘, newPrice: 255, oldPrice: 752},
                {type: ‘B‘, newPrice: 120, oldPrice: 560},
                {type: ‘C‘, newPrice: 325, oldPrice: 699},
            ],
            setMealItems: [
                {imgSrc: require(‘../../../static/setMeal/setMeal_icon_02.png‘), txt: ‘特制营养早餐‘, info: ‘免费‘},
                {imgSrc: require(‘../../../static/setMeal/setMeal_icon_03.png‘), txt: ‘检中医护免费咨询‘, info: ‘现场‘},
                {imgSrc: require(‘../../../static/setMeal/setMeal_icon_04.png‘), txt: ‘主检医生总结报告‘, info: ‘10日‘}
            ]
        }
    },
    created() {
        this.setMealId = this.$route.query.id;
    },
    watch: {
//      ‘$route‘ (to, from) {
//          if(to.query.id !== from.query.id){
//              location.reload();//此方法页面会空白再显示，交互体验不好
//          }
//      }
        $route(){
            this.setMealId = this.$route.query.id
        },
        setMealId() {
            this.setMealDetail();
        },
    },
    methods: {
        setMealDetail() {
            //axios请求
        }
    }
}
