vue-awesome-swiper轮播插件

1. github上搜索vue-awesome-swiper

2. readme中有安装方法,建议在插件名后@版本号,使用稳定的老版本 npm install vue-awesome-swiper@x.x.x --save 

3. 在项目main.js中引入

import vue from 'vue'
import vueawesomeswiper from 'vue-awesome-swiper'

// require styles
import 'swiper/dist/css/swiper.css'

vue.use(vueawesomeswiper, /* { default global options } */)

4.创建单文件组件swiper.vue(单文件组件三部分template、script、style)

<template>
    <swiper :options="swiperoption">
        <!-- slides -->
     //这里是轮播的内容 <swiper-slide>i'm slide 1</swiper-slide> <swiper-slide>i'm slide 2</swiper-slide> <swiper-slide>
      <img src=""/>
     </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>
     //两个箭头,不需要可以删了 <div class="swiper-button-prev" slot="button-prev"></div> <div class="swiper-button-next" slot="button-next"></div>
     //滚动条,不需要可以删了 <div class="swiper-scrollbar" slot="scrollbar"></div> </swiper> </template> <script> export default { name: 'homeswiper', // 子组件的data必须是个函数 data() { return { swiperoption: {} } }, } </script> <style lang="stylus" scoped> </style>

5. 在别的页面中引用,如在home.vue

<template>
    <div>
        <home-header></home-header>
        <home-swiper></home-swiper>
    </div>
</template>

<script>
import homeheader from './component/header'
import homeswiper from './component/swiper'
export default {
    name: 'home',
    components: {
        homeheader,
        homeswiper
    }

}
</script>

<style lang="stylus">
  
</style>

6.防抖动:在网速不好的情况下,swiper未加载出前,下方的div会占据,等到swiper出来时,占据位置的div会蹦走

处理方法:swiper外层嵌套div,让这个div撑开高度

<template>
    <div class="wrapper">
        <swiper :options="swiperoption">
            ...
        </swiper>
    </div>
</template>

<script>
    ...
</script>

<style lang="stylus" scoped>
  .wrapper
    overflow: hidden
    width:100%
    height:0
    padding-bottom: 31.25%   (宽高比,如果写在height,那么是和父级元素的高度,不是对比wrapper的宽度)
</style>

7.轮播图下面跟着跑的一排小圆点

<template>
    <div class="wrapper">
        <swiper :options="swiperoption">
            <!-- slides -->
            <swiper-slide>i'm slide 1</swiper-slide>
            <swiper-slide>i'm slide 2</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',
    // 子组件的data必须是个函数
    data() {
        return {
            swiperoption: {
                pagination: 'swiper-pagination'
            }
        }
    },
}
</script>

<style lang="stylus" scoped>
  //三个箭头是穿透,这样就突破了scoped的限制
  //这个class名从何而来,是从页面中审查元素得到的
  .wrapper >>> .swiper-pagination-bullet-active
    background: red !important
  .wrapper
    overflow: hidden
    width:100%
    height:0
    padding-bottom: 31.25%   (宽高比,如果写在height,那么是和父级元素的高度,不是对比wrapper的宽度)
</style>

8.vue是数据驱动的框架,轮播的图片地址和数量不该固定写死

处理方法:v-for循环item,注意循环要加key

<template>
    <div class="wrapper">
        <swiper :options="swiperoption">
            <!-- slides -->
            <swiper-slide v-for="item of swiperlist" :key="item.id">
          <img :src="item.imgurl" />
       </swiper-slide> <!-- optional controls --> <div class="swiper-pagination" slot="pagination"></div> </swiper> </div> </template> <script> export default { name: 'homeswiper', // 子组件的data必须是个函数 data() { return { swiperoption: { pagination: 'swiper-pagination' }, swiperlist: [{ id: '0001', imgurl: 'http://lkadand.adoaidiajd.jada.jpg' }, { id: '0002', imgurl: 'jndakm.adkand.sda.jpg' }] } }, } </script> <style lang="stylus" scoped> //三个箭头是穿透,这样就突破了scoped的限制 //这个class名从何而来,是从页面中审查元素得到的 .wrapper >>> .swiper-pagination-bullet-active background: red !important .wrapper overflow: hidden width:100% height:0 padding-bottom: 31.25% (宽高比,如果写在height,那么是和父级元素的高度,不是对比wrapper的宽度) </style>

9.循环轮播

处理方法:加loop值为true

<template>
    <div class="wrapper">
        <swiper :options="swiperoption">
            <!-- slides -->
            <swiper-slide v-for="item of swiperlist" :key="item.id"><img :src="item.imgurl" /></swiper-slide>
            <!-- optional controls -->
            <div class="swiper-pagination" slot="pagination"></div>
        </swiper>
    </div>
</template>

<script>
export default {
    name: 'homeswiper',
    // 子组件的data必须是个函数
    data() {
        return {
            swiperoption: {
                pagination: 'swiper-pagination',
                loop: true
            },
            swiperlist: [{ id: '0001', imgurl: 'http://lkadand.adoaidiajd.jada.jpg' }, { id: '0002', imgurl: 'jndakm.adkand.sda.jpg' }]
        }
    },
}
</script>

<style lang="stylus" scoped>
  //三个箭头是穿透,这样就突破了scoped的限制
  //这个class名从何而来,是从页面中审查元素得到的
  .wrapper >>> .swiper-pagination-bullet-active
    background: red !important
  .wrapper
    overflow: hidden
    width:100%
    height:0
    padding-bottom: 31.25%   (宽高比,如果写在height,那么是和父级元素的高度,不是对比wrapper的宽度)
</style>
