使用 Vue.js 进行操作的路由器

Question

我正在学习 vue.js，我正在使用 Vuetify 官方网站上的这段代码来练习预先制作的布局。我该怎么做哟 我的意思是，当您按下侧菜单上的某个按钮时，无需刷新页面即可将信息加载到其他地方

提前谢谢...

Answer 1

你要找的是 vue-router (npm i vue-router)，然后如下设置你的 main.js 页面

import Vue from 'vue'
import App from './App.vue'
import Home from './components/Home.vue'
import About from './components/About.vue'
import Contact from './components/Contact.vue'

import vuetify from './plugins/vuetify';
Vue.config.productionTip = false;

import VueRouter from 'vue-router'
Vue.use(VueRouter)
const router = new VueRouter({
  mode: 'history',
  routes: [
    { name: 'home', path: '/', component: Home},
    { name: 'about', path: '/about', component: About},
    { name: 'contact', path: '/contact', component: Contact}
  ]
})

new Vue({
  vuetify,
  router
  render: h => h(App)
}).$mount('#app')

而在 App.vue 中你需要加载 <router-view>

<template>
  <keep-alive>
    <router-view></router-view>
  </keep-alive>
</template>
<script>
export default {
  name: "App"
};
</script>

您可以简单地添加一些 href <a href="/about">About</a> 来在页面之间导航，或者您可以在 v-btn 中使用 :to 属性，如果您有其他一些没有 :to 属性的 vuetify 元素，那么您可以换行<router-link>中的元素

<router-link :to="/about">
  <span>About</span>
</router-link>
