Vue-Router的使用（一）

// 1. 定义路由组件
// 可以自己写的，或者导入的，大部分是导入的
const Foo = { template: ‘<div>foo</div>‘ }
const Bar = { template: ‘<div>bar</div>‘ }

// 2. 定义路由规则
// 每个路由映射一个组件
const routes = [
  { path: ‘/foo‘, component: Foo },
  { path: ‘/bar‘, component: Bar }
]
//导出使用
export default=routes;

import Vue from ‘vue‘
import VueRouter from ‘vue-router‘
import routes from "./Admin/route/route.js";//导入路由文件
//使用插件
Vue.use(VueRouter)
//实例化
const router = new VueRouter({
    routes,
    mode: ‘history‘
})
//使用
new Vue({
    el: ‘#app‘,
    template: "<div><router-view></router-view></div>",
    router
})

// Home.vue
<template>

<div id="app">
  <h1>Hello App!</h1>
  <p>
    <!-- use router-link component for navigation. -->
    <!-- specify the link by passing the `to` prop. -->
    <!-- `<router-link>` will be rendered as an `<a>` tag by default -->
    <router-link to="/foo">Go to Foo</router-link>
    <router-link to="/bar">Go to Bar</router-link>
  </p>
  <!-- route outlet -->
  <!-- component matched by the route will render here -->
  <router-view></router-view>
</div>

</template>
<script>
export default {
  computed: {
    username () {
      // We will see what `params` is shortly
      return this.$route.params.username
    }
  },
  methods: {
    goBack () {
      window.history.length > 1
        ? this.$router.go(-1)
        : this.$router.push(‘/‘)
    }
  }
}
</script>

router.push(location, onComplete?, onAbort?)
例子：
const userId = 123
router.push({ name: ‘user‘, params: { userId }}) // -> /user/123
router.push({ path: `/user/${userId}` }) // -> /user/123
// This will NOT work
router.push({ path: ‘/user‘, params: { userId }}) // -> /user

router.go(n)
例子：
   // go forward by one record, the same as history.forward()
router.go(1)

// go back by one record, the same as history.back()
router.go(-1)
