还是老办法，先运行项目看看效果
我不算是外卖爱好者，不过觉得那个添加商品到购物车的动画效果很好看很有趣
最近的框架好多，简直应接不暇，比如上篇的博客，我甚至以为作者大大自己封装一系列组件写项目，
搜索了一下才发现居然是van有赞小程序。
这个demo用到的是cube-ui也是一个框架，好像是滴滴的。
我一下子就惊吓到了。新的技术层出不穷，我会的和用到的都比较少，做观众欣赏别人的代码和产品也很有意思。
我们还是看代码吧
//main.js
import Vue from 'vue'
import App from './App.vue'
// 引入cube-ui
import './cube-ui'
// 引入注册组件文件
import './register'
import 'common/stylus/index.styl'
Vue.config.productionTip = false
new Vue({
render: h => h(App)
}).$mount('#app')
主要说的意思就是页面是从app.vue进行渲染的，先看看register中引入了组件
//register.js
// cube-ui的用法
import { createAPI } from 'cube-ui'
import Vue from 'vue'
import HeaderDetail from 'components/header-detail/header-detail'
import ShopCartList from 'components/shop-cart-list/shop-cart-list'
import ShopCartStikcy from 'components/shop-cart-sticky/shop-cart-sticky'
import Food from 'components/food/food'
createAPI(Vue, HeaderDetail)
createAPI(Vue, ShopCartList)
createAPI(Vue, ShopCartStikcy)
createAPI(Vue, Food)
接下来看app.vue中做了什么
先看最上面的
引入了组件
//v-header.vue
<template>

vue提供的 @touchmove.prevent 可以用来阻止滑动，但是这个方法会对其内的子div的滑动事件也禁止掉了，这样会导致中间文字无法滑动。
如果没有中间滑动需求，用 @touchmove.prevent 实现是一个很好的方法。
我们接下来看seller组件
他的页面是
