1.vue-router:點選導航按鈕顯示相應頁面

1.router/index.vue

import Vue from 'vue'
import Router from 'vue-router'
import header from '@/components/header/header'
import ratings from '@/components/ratings/ratings'
import seller from '@/components/seller/seller'
import goods from '@/components/goods/goods'

Vue.use(Router)

export default new Router({
  routes: [
    {
      path: '/header',
      name: 'header',
      component: header
    },
    {
      path: '/ratings',
      name: 'ratings',
      component: ratings
    },
    {
      path: '/seller',
      name: 'seller',
      component: seller
    },
    {
      path: '/goods',
      name: 'goods',
      component: goods
    }
  ]
});
 

2.App.vue

<template>
  <div id="app">
    <v-header></v-header>
    <div class="tab">
      <div class="tab-item">
        <router-link to='/goods'>商品</router-link>
      </div>
       <div class="tab-item">
         <router-link to='/ratings'>評論</router-link>
       </div>
       <div class="tab-item">
         <router-link to='/seller'>商家</router-link>
       </div>
    </div>
    <router-view></router-view>
  </div>
</template>

<script>
  import header from './components/header/header'

  export default{
    components:{
      'v-header':header
    }
  }
</script>

<style type="text/css" lang="stylus" rel="stylesheet/stylus">
  #app
   .tab
    display: flex
    width: 100%
    height: 40px
    line-height: 40px
    .tab-item
     flex: 1
     text-align: center
</style>
 

3.main.js

// The Vue build version to load with the `import` command
// (runtime-only or standalone) has been set in webpack.base.conf with an alias.
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/>'
})

router.push('/goods')//這裡不再使用router.go() 改用router.push()
 

2.mock後臺資料，axios獲取資料

1.webpack.dev.conf.js

'use strict'
const utils = require('./utils')
const webpack = require('webpack')
const config = require('../config')
const merge = require('webpack-merge')
const path = require('path')
const baseWebpackConfig = require('./webpack.base.conf')
const CopyWebpackPlugin = require('copy-webpack-plugin')
const HtmlWebpackPlugin = require('html-webpack-plugin')
const FriendlyErrorsPlugin = require('friendly-errors-webpack-plugin')
const portfinder = require('portfinder')

//新增mock 資料
const express = require('express')
const app = express()
var appData = require('../data.json')//載入本地資料檔案
var seller=appData.seller
var goods=appData.goods
var ratings=appData.ratings

const HOST = process.env.HOST
const PORT = process.env.PORT && Number(process.env.PORT)

   watchOptions: {
      poll: config.dev.poll,
    },
    before(app) {
     app.get('/api/seller', function (req, res) {
       res.json({
         errno: 0,
         data: seller
       });
     });
     app.get('/api/goods', function (req, res) {
       res.json({
         errno: 0,
         data: goods
       });
     });
     app.get('/api/ratings', function (req, res) {
       res.json({
         errno: 0,
         data: ratings
       });
     });
   }
  },
  plugins: [
    new webpac

2.npm run dev之後，App.vue驗證資料正確性

<script>
  import header from './components/header/header'
  import axios from 'axios'

  export default{
    data(){
      return {
        seller: {}
      };
    },
    components: {
      'v-header':header
    },
    created:function(){
        //常用商品
        axios.get('http://localhost:8082/api/goods')
        .then(response=>{
          console.log(response);
        })
        .catch(error=>{
          // console.log(error);
          alert('網路錯誤，不能訪問');
        })
    }
  }
</script>

3.seller.supports加入判斷 否則出錯。因為資料created()後才傳入

<div class="header">
		<!-- 內容區 -->
		<div class="content-wrapper">
			<div class="avatar">
				<img width="64" height="64" :src="seller.avatar">
			</div>
			<div class="content">
				<div class="title">
					<span class="brand"></span>
					<span class="name">{{seller.name}}</span>
				</div>
				<div class="description">
					{{seller.description}}/{{seller.deliveryTime}}分鐘送達
				</div>
				<div v-if='seller.supports'>
					<div class="icon"></div>
					<span class="text">{{seller.supports[0].description}}</span>
				</div>
			</div>
		</div>
		<!-- 公告區 -->
		<div class="bulletin-wrapper"></div>
	</div>
