## :-: [Vue CLI3.0 中使用jQuery 和 Bootstrap - 简书](https://www.jianshu.com/p/0d0c1eaeb877) ## :-: vue - router Demo :-:  :-: main.js ``` import Vue from 'vue' import App from './App.vue'; import router from './router.js';

import x2js from 'x2js' //xml数据处理插件 import store from './store' Vue.prototype.$x2js = new x2js() //创建x2js对象，挂到vue原型上 Vue.config.productionTip = false; // 全局守卫 (main.js) // 进页面前触发 router.beforeEach((to, from, next) => { // if (['student', 'academic'].includes(to.name)) return; // some every let needLogin = to.matched.some(ele => ele.meta && ele.meta.login === true); if (needLogin) { // 判断是否需要登陆 let isLogin = document.cookie.includes('login=true'); if (isLogin) { next(); } else { isLogin = window.confirm('该页面需要登陆后才能访问 ~'); if (isLogin) { next('/login'); } // 需要登陆 } } else { next(); } }); // // 解析完毕执行 // router.beforeResolve((to, from, next) => { // // to and from are both route objects. must call `next`. // // next(); // }) new Vue({ router, store, render: h => h(App) }).$mount('#app');
