使用vue-router

1. 在src文件夹下 -- 新建router文件夹 -- 新建index.js

2. 在index.js中引入vue、vue-router

• import Vue from 'vue'
• import VueRouter from 'vue-router'
• Vue.use(VueRouter)

3. 在index.js中声明一个VueRouter实例

• export default new VueRouter({ routes: [ { path:'/home', component: Home } ] })

4. 在main.js中引入router、并在new Vue({}) 实例中添加router

• import router from './router'
• new Vue({router})

5. 通过<router-view></router-view>显示

6. router-link

• <router-link to="/home">Home</router-link>
• <router-link :to="{path:'/home'}">Home</router-link>
• <router-link :to="{name:'home'}">Home</router-link>
• <router-link :to="{name:'home'}" tag="li">Home</router-link>
把<router-link></router-link> 渲染成li标签

eg:

• App.vue

    <template>
      <div id="app">
        <div>我是APP</div>
        <a href="#/home">Home</a>  // 这里的地址要写 #/ 或者给index.js中的VueRouter实例配置一个mode字段 mode:'history'（这个字段会刷新页面）
        <a href="#/about">About</a>
    
        <li><router-link to="/home">Home</router-link></li>
        <li><router-link to="/doc">Doc</router-link></li>
        <li><router-link to="/about">About</router-link></li>
        <router-view></router-view>
    
      </div>
    </template>
    
    <script>
    export default {
      name: 'App'
    }
    </script>

eg:

• index.js

    import Vue from 'vue'
    import VueRouter from 'vue-router'
    import Home from '../components/home.vue'
    import About from '../components/about.vue'
    
    Vue.use(VueRouter)
    
    export default new VueRouter({
        routes: [
            {
                path:'/home',
                name: 'home', // 如果路由很深，用name会方便一些
                component: Home
            },
            {
                path:'/about',
                component: About
            }
        ]
    })

eg:

• main.js

    import Vue from 'vue'
    import App from './App'
    import router from './router'
    
    Vue.config.productionTip = false
    
    /* eslint-disable no-new */
    new Vue({
      el: '#app',
      router,
      components: { App },
      template: '<App/>'
    })

eg:

• home.js

    <template>
        <div>我是{{title}}</div>
    </template>
    <script>
    import Home from '../components/home'
    export default {
        data() {
            return {
                title: 'HOME'
            }
        }
    }
    </script>

eg:

• about.js

    <template>
        <div>我是{{title}}</div>
    </template>
    <script>
    import About from '../components/about'
    export default {
        data() {
            return {
                title: 'ABOUT'
            }
        }
    }
    </script>
