Vue 简单实例 购物车1

1、新创建一个项目：freemall

2、安装依赖：axios、vue-axios

3、配置路由

import Vue from 'vue'
import VueRouter from 'vue-router'
import Cart from '../pages/Cart.vue'
import Address from '../pages/Address.vue'

Vue.use(VueRouter)

const routes = [
  {
    path: '/',
    name: 'Cart',
    component: Cart
  },
  {
    path: '/address',
    name: 'Address',
    component: Address
  }
]

const router = new VueRouter({
  mode: 'history',
  base: process.env.BASE_URL,
  routes
})

export default router

4、App.vue文件：

<template>
  <div id="app">
    <router-view />
  </div>
</template>

5、入口文件main.js：

import Vue from 'vue'
import App from './App.vue'
import router from './router'
import store from './store'
import axios from 'axios'
import VueAxios from 'vue-axios'
import './assets/css/base.css'
import './assets/css/index.css'

Vue.use(VueAxios, axios)
// 提示开关
Vue.config.productionTip = false

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

引入 axios 及样式文件。

6、在 components 目录下新建 Header.vue、Footer.vue、Modal.vue 文件

头、尾文件就不写了，Modal.vue文件：

<template>
  <div style="display: none">
    <div class="md-modal modal-msg md-modal-transition md-show">
      <div class="md-modal-inner">
        <div class="md-top">
          <button class="md-close" @click="closeModal">关闭</button>
        </div>
        <div class="md-content">
          <div class="confirm-tips">
            <p slot="message">你确认要删除此条数据吗?</p>
          </div>
          <div class="btn-wrap">
            <a slot="btnGroup" class="btn btn--m" href="javascript:;">确认</a>
            <a slot="btnGroup" class="btn btn--m btn--red" href="javascript:;">关闭</a>
          </div>
        </div>
      </div>
    </div>
    <div class="md-overlay" @click="closeModal"></div>
  </div>
</template>

7、在 public 目录下，新建 mock 文件夹，复制粘贴 cart.json 和 address.json 文件。

8、新建 pages目录，创建 Cart.vue 文件：

引入Header、Footer、Modal组件，并发起请求：

<template>
  <div>
    <nav-header></nav-header>
    <div class="nav-breadcrumb-wrap">
      <div class="container">
        <nav class="nav-breadcrumb">
          <a href="/">首页</a>
          <span>购物车</span>
        </nav>
      </div>
    </div>
    <!-- 定义购物车页面图标 -->
    <svg
      style="position: absolute;  0; height: 0; overflow: hidden;"
