vue开发 - 根据vue-router的meta动态设置html里title标签内容

import Vue from ‘vue‘
import Router from ‘vue-router‘
import index ‘@/view/index‘
import user from ‘@/view/user‘
Vue.use(Router)
export default new Router({
    routes: [
        {
            path: ‘/index‘,
            name: ‘index‘,
            component: index,
            meta:{
                title:‘首页‘
            }
        },
        {
            path: ‘/user‘,
            name: ‘user‘,
            component: user,
            meta:{
                title:‘个人中心‘
            }
        }
    ]
})

 1 import Vue from ‘vue‘
 2 import App from ‘./App‘
 3 import router from ‘./router‘
 4 router.beforeEach((to, from, next) => {
 5     if (to.meta.title) {
 6         document.title = to.meta.title
 7     }
 8     next()
 9 })
10 new Vue({
11     el: ‘#app‘,
12     router,
13     template: ‘<App/>‘,
14     components: {App}
