Vue使用Swiper
Tyler Yue 人气:0Vue使用Swiper看这一篇就够了
此案例实现需求
- 完成swiper动态异步数据下的slide渲染
- 自定义分页器样式
- 解决loop:true设置时的事件丢失问题
- swiper鼠标移入/移出 暂停/开始轮播
- 单页面渲染多个swiper组件互不影响
1、引入swiper
npm i swiper@5.2.0
2、创建轮播图组件CarouselContainer.vue,详细解析在代码注释中
<template> <div class="CarouselContainer" @mouseenter="stopAutoPlay" @mouseleave="startAutoPlay"> <div ref="mySwiper" class="swiper-container" :id="currentIndex" > <div class="swiper-wrapper"> <div class="swiper-slide my-swiper-slide" v-for="(item,index) of slideList" :key="index">{{item.name}}</div> </div> <!-- 分页器 --> <div class="swiper-pagination"></div> <!--导航器--> <div class="swiper-button-prev"></div> <div class="swiper-button-next"></div> </div> </div> </template> <script> import Swiper from 'swiper' import "swiper/css/swiper.css"; export default { name: 'CarouselContainer', props: ['slideList','currentIndex'], data(){ return { currentSwiper:null, } }, watch:{ //slide数据发生变化时,更新swiper slideList:{ deep:true, // eslint-disable-next-line handler(nv,ov){ console.log("数据更新了") this.updateSwiper() } } }, mounted() { this.initSwiper() }, methods:{ //鼠标移入暂停自动播放 stopAutoPlay() { this.currentSwiper.autoplay.stop() }, //鼠标移出开始自动播放 startAutoPlay() { this.currentSwiper.autoplay.start() }, //初始化swiper initSwiper(){ // eslint-disable-next-line let vueComponent=this//获取vue组件实例 //一个页面有多个swiper实例时,为了不互相影响,绑定容器用不同值或变量绑定 this.currentSwiper = new Swiper('#'+this.currentIndex, { loop: true, // 循环模式选项 autoHeight:'true',//开启自适应高度,容器高度由slide高度决定 //分页器 pagination: { el: '.swiper-pagination', clickable:true,//分页器按钮可点击 }, on: { //此处this为swiper实例 //切换结束获取slide真实下标 slideChangeTransitionEnd: function(){ console.log(vueComponent.$props.currentIndex+"号swiper实例真实下标",this.realIndex) }, //绑定点击事件,解决loop:true时事件丢失 // eslint-disable-next-line click: function(event){ console.log("你点击了"+vueComponent.$props.currentIndex+"号swiper组件") } }, //导航器 navigation: { nextEl: '.swiper-button-next', prevEl: '.swiper-button-prev', }, autoplay: { //自动播放,不同版本配置方式不同 delay: 3000, stopOnLastSlide: false, disableOnInteraction: false }, slidesPerView: 1, //视口展示slide数1 slidesPerGroup: 1, //slide数1页一组 }) }, //销毁swiper destroySwiper(){ try { this.currentSwiper.destroy(true,false) }catch (e) { console.log("删除轮播") } }, //更新swiper updateSwiper(){ this.destroySwiper() this.$nextTick(()=>{ this.initSwiper() }) }, }, destroyed() { this.destroySwiper() } } </script> <style scoped> .CarouselContainer{ background-color: gray; } /*slide样式*/ .my-swiper-slide{ height: 300px; background-color: pink; } /*swiper容器样式*/ .swiper-container { width: 700px; border: 1px solid red; } /*自定义分页器按钮被点击选中时的样式*/ /deep/.swiper-pagination-bullet-active{ background-color: #d5a72f !important; width: 20px; } /*自定义分页器按钮常规样式*/ /deep/.swiper-pagination-bullet{ background-color: #9624bf; opacity: 1; width: 20px; } </style>
3、创建父组件App.vue渲染多个swiper组件、模拟异步数据变化
<template> <div id="app"> <!--传递不同的currentIndex 作为区分不同swiper组件的动态id--> <CarouselContainer :slide-list="list" currentIndex="1"></CarouselContainer> <CarouselContainer :slide-list="list" currentIndex="2"></CarouselContainer> </div> </template> <script> import CarouselContainer from './components/CarouselContainer.vue' export default { name: 'App', components: { CarouselContainer, }, data(){ return{ list:[ {name:"aaa"}, {name:"bbb"}, {name:"ccc"}, ] } }, mounted() { let self=this //延时模拟两次数据变化 setTimeout(()=>{ let obj={name:"ddd"} self.list.push(obj) },5000) setTimeout(()=>{ let obj={name:"eee"} self.list[0].name="AAA" self.list.push(obj) },8000) } } </script> <style scoped> </style>
只需要这两个文件就可以vue项目中运行demo查看效果了
