Posted 2020-10-27 赵理通

router.js

    routes: [{
            path: ‘/‘,
            name: ‘HelloWorld‘,
            component: HelloWorld,
            meta: {
                title: "HelloWorld",    要现实的title
                show: true               设置导航隐藏显示
            }

        }]

 

App.vue

<template>
	<div id="app">
		<router-view></router-view>
		<bottom v-show="this.$route.meta.show"></bottom>   this.$route.meta.show  显示或隐藏

</div> </template>

　　

main.js

 

router.beforeEach((to, from, next) => {

    if (to.meta.title) {
        document.title = to.meta.title
    }
    next()
})

监听路由 写入 title
