問題描述

目前在做一個小demo，使用了parcel+vue+vue-router+axios+muse-ui，實踐中需要使用keep-alive保證組件不會被刷新，當點擊該問題組件跳轉其詳情組件的時候，居然觸發(fā)了該組件的鉤子函數，使得該組件的ajax請求又發(fā)了一遍

• router：

    import ('../components/DailyDetail.vue')
export default new Router({

你期待的結果是什么？實際看到的錯誤信息又是什么？

我期望的結果是需要實現(xiàn)keep-alive的效果，并且不能讓再觸發(fā)鉤子函數。
