使用了Vue-cli开发 封装

先来看效果吧

效果图

swiper-view由两个部分组成

使用vue-awesome-swiper

//main.js
import VueAwesomeSwiper from 'vue-awesome-swiper'
import 'swiper/dist/css/swiper.css'
import 'swiper/dist/js/swiper.min'

1.header
2.content

swiper-view组件结构

控制header参数

参数 介绍 类型 可选值 默认值

方法

控制content参数

方法

父组件使用方式

注意dataList的json结构...键一定要是title,component

<template>
  <div class="father">
    <swiper-view :dataList="dataList"
                 ref="swiperView">

      <demo-a slot="demoA"></demo-a>
      <demo-b slot="demoB"></demo-b>
      <demo-c slot="demoC"></demo-c>
      
       <!--优雅写法,但是不好操作，直接显示的话可以用这个-->
<!--
        <component :is="item.component"
                   :slot="item.component"
                   v-for="(item,id) of dataList"
                   :key="id">
        </component>
-->
    </swiper-view>
  </div>
</template>

<script>
import swiperView from 'common/components/swiperView/swiperView'
name:"father"
components: {
    swiperView,
    demoA: () => import('./otherComponents/demoA'),
    demoB: () => import('./otherComponents/demoB'),
    demoC: () => import('./otherComponents/demoC')
  },
data () {
    return {
      dataList:
        [{ title: 'demo1',
          component: 'demoA'
        },
        { title: demo2',
          component: 'demoB'
        },
        { title: 'demo3',
          component: 'demoC'
        }]
    }    
  },
</script>

操作swiper

在swiper-view中定义ref 写在计算属性中，就可以拿来使用了

//父组件
<template>
  <div class="mind-swiper-view-wrapper">
    <swiper-view ref="swiperView">
    </swiper-view>
  </div>
</template>

<script>
//引入
import swiperView from 'common/components/swiperView/swiperView'
 
mounted () {
  console.log(this.viewEL.tabsSwiper)  //Swiper {…}
  console.log(this.viewEl.viewSwiper) //Swiper {…}
},
computed: {
  viewEL () {
    return this.$refs.swiperView
  }
}
</script>

父组件修改样式

使用 >>> 穿透的方式修改

.mind-swiper-view-wrapper>>>.bar .color {
  background: red !important;
}

给header的item加上icon

//父组件
</template>
    <div class="iconfont iconClass"
         slot="demoA0">
    </div>
</template>

slot为component名字+index

源码

<template>
  <div class="swiperView-wrapper">

    <!-- header -->
    <div class="swiperView-header"
         ref="header">
      <!-- icon -->
