跟我一起做一个vue的小项目（三）

接下来我们进行轮播的开发

安装插件，选用2.6.7的稳定版本

npm install vue-awesome-swiper@2.6.7 --save

根据其github上面的用法，我们在全局引用，在main.js中添加

//main.js
import VueAwesomeSwiper from 'vue-awesome-swiper'
require('swiper/dist/css/swiper.css')
Vue.use(VueAwesomeSwiper)

在components里面写入Swiper.vue

<template>
<div class="wrapper">
   <swiper :options="swiperOption">
    <!-- slides -->
    <swiper-slide v-for="item of swiperList" :key="item.id">
      <img class="swiper-img" :src="item.imgUrl">
    </swiper-slide>
    <!-- <swiper-slide>
      <img class="swiper-img" src="">
    </swiper-slide> -->
    <!-- <swiper-slide>I'm Slide 3</swiper-slide>
    <swiper-slide>I'm Slide 4</swiper-slide>
    <swiper-slide>I'm Slide 5</swiper-slide>
    <swiper-slide>I'm Slide 6</swiper-slide>
    <swiper-slide>I'm Slide 7</swiper-slide> -->
    <!-- Optional controls -->
    <div class="swiper-pagination"  slot="pagination"></div>
    <!-- <div class="swiper-button-prev" slot="button-prev"></div>
    <div class="swiper-button-next" slot="button-next"></div>
    <div class="swiper-scrollbar"   slot="scrollbar"></div> -->
  </swiper>
</div>
</template>
<script>
export default {
  name: 'HomeSwiper',
  data () {
    return {
      swiperOption: {
        pagination: '.swiper-pagination',
        loop: 'true'
      },
      swiperList: [{
        id: '001',
        imgUrl: 'http://mp-piao-admincp.qunarzz.com/mp_piao_admin_mp_piao_admin/admin/20193/d7bbc21db442366a882e04ddc984669a.jpg_750x200_85e640d9.jpg'
      }, {
        id: '002',
        imgUrl: 'http://mp-piao-admincp.qunarzz.com/mp_piao_admin_mp_piao_admin/admin/20196/5e02c14d35097f40d656f455837b63eb.jpg_750x200_adebb937.jpg'
      }]
    }
  }
}
</script>
<style lang="stylus" scoped>
  .wrapper >>> .swiper-pagination-bullet-active
    background:#fff !important
  .wrapper
    overflow:hidden
    width:100%
    height:0
    padding-bottom:26.67%
    background:#eee
  .swiper-img
    width:100%
</style>

运行项目，效果为



关于轮播的话，这个里面比较有意思的是对局部组件样式的一个修改，用到了>>>，然后的话就是将数据写入对象数组中，

循环展示在页面中，这个的话，一般其实我们是从后端数据中获取的。
