export default {
name: ‘App’,
created () {
//在页面加载时读取sessionStorage里的状态信息
if (sessionStorage.getItem(“store”) ) {
this.$store.replaceState(Object.assign({}, this.$store.state,JSON.parse(sessionStorage.getItem(“store”))))
}
//在页面刷新时将vuex里的信息保存到sessionStorage里
window.addEventListener(“beforeunload”,()=>{
sessionStorage.setItem(“store”,JSON.stringify(this.$store.state))
})
}
}
