3-vuejs2.0实战：仿豆瓣app项目，创建Swipe图片轮

swipe图片轮播不管是在pc端，还是移动端都是常见的效果，在这一章将用开源插件swiper完成一个比较简单的swipe循环轮播组件.最近公司太忙，更新慢，请见谅~~

官网介绍：

Swiper是纯javascript打造的滑动特效插件，面向手机、平板电脑等移动终端。
Swiper能实现触屏焦点图、触屏Tab切换、触屏多图切换等常用效果。
Swiper开源、免费、稳定、使用简单、功能强大，是架构移动终端网站的重要选择！

swiper中文文档：http://www.swiper.com.cn

我们在components文件夹里创建一个swipe组件，将需要用到的js以及css文件复制到assets/lib文件夹下，如图：

然后根据swiper的使用方法：http://www.swiper.com.cn/usage/index.html

将html结构复制到swipe组件里，引入css文件，以及js

<template>
  <div class="swiper-container">
    <div class="swiper-wrapper">
      <div class="swiper-slide">Slide 1</div>
        <div class="swiper-slide">Slide 2</div>
        <div class="swiper-slide">Slide 3</div>
    </div>
    <!-- 分页器 -->
   <div class="swiper-pagination"></div>
  </div>
</template>
<script>
  import '../assets/lib/swiper/js/swiper.js'
  export default {
    mounted() {
     var mySwiper = new Swiper ('.swiper-container', {
     loop: true,
    // 如果需要分页器
    pagination: '.swiper-pagination',
  })        
    }
  }

</script>
<style>
  @import '../assets/lib/swiper/css/swiper.css';
  .swiper-pagination-bullet-active {
    background: #fff;
  }

</style>

保存预览会报错，我们将swiper.js尾部需要修改一下

将AMD模式删掉，改成

export default window.Swiper;

我们可能在一个页面引用多个swipe组件，就会发生命名冲突，所以我们在实例化swiper的时候，类名需要变化一下，例如：

<m-swipe swipeid="swipe01"></m-swipe>
<m-swipe swipeid="swipe02"></m-swipe>

<div class="swiper-container" :class="swipeid">
    <div class="swiper-wrapper">
      <div class="swiper-slide">Slide 1</div>
        <div class="swiper-slide">Slide 2</div>
        <div class="swiper-slide">Slide 3</div>
    </div>
    <!-- 分页器 -->
    <div class=".swiper-pagination"></div>
  </div>
 export default {
    props: {
      swipeid: {
        type: String,
        default: 'swipe01'
      }
    },
    mounted() {
      var That = this;
      new Swiper('.'+That.swipeid, {
          loop: true,
          // 如果需要分页器
          pagination: '.swiper-pagination',
      })
    }

简单的swipe组件就完成了，我们再来丰富他的配置参数，改成可传递参数的组件。具体参数参考中文api文档：http://www.swiper.com.cn/api/index.html

swipe.vue

<template>
  <div class="swiper-container" :class="swipeid">
    <div class="swiper-wrapper">
      <slot name="swiper-con"></slot>
    </div>
    <!-- 分页器 -->
    <div :class="{'swiper-pagination':pagination}"></div>
  </div>
</template>
<script>
  import '../assets/lib/swiper/js/swiper.js'
  export default {
    props: {
      swipeid: {
        type: String,
        default: ''
      },
      effect: {
        type: String,
        default: 'slide'
      },
      loop: {
        type: Boolean,
        default: true
      },
      direction: {
        type: String,
        default: 'horizontal'
      },
      pagination: {
        type: Boolean,
        default: true
      },
      autoplay: {
        type: Number,
        default: 5000,
      },
      paginationType: {
        type: String,
        default: 'bullets'
      }
    },
    mounted() {
      var That = this;
      new Swiper('.'+That.swipeid, {
        //循环
        loop: That.loop,
        //分页器
        pagination: '.swiper-pagination',
        //分页类型
        paginationType: That.paginationType, //fraction,progress,bullets
        //自动播放
        autoplay: That.autoplay,
        //方向
        direction: That.direction,
        //特效
        effect: That.effect, //slide,fade,coverflow,cube

      })
    }
  }
