The problem will disappear when refreshing the page data in vuex

Solution:

　　　　Change the definition of the state of the index file under the store file

const store = new Vuex.Store({
    state:sessionStorage.getItem('state') ? JSON.parse(sessionStorage.getItem('state')): {
        //id
        skillId:'',
        //技能状态
        checkStatus:''
    }
})

　　　　And add in App.vue

　　　　　mounted() {
            window.addEventListener('unload', this.saveState)
        },
        methods: {
            saveState() {
                sessionStorage.setItem('state', JSON.stringify(this.$store.state))
            }
        }

　　　　In other words, listen to the unload method, if you reload the page, store the state in sessionStorage, and then take the value from sessionStorage when the state is needed.
