vue.js实现的幻灯片功能示例
本文实例讲述了vue.js实现的幻灯片功能。分享给大家供大家参考,具体如下:
1、在父组件中
<slide-show :slides="slides"></slide-show> import SlideShow from '@/components/SlideShow' export default { components: { SlideShow, },
2、在slideshow.vue中
<template> <div class="slide-show" @mouseover="clearInv" @mouseout="runInv"> // 当鼠标移入的时候清除,移出的时候 <div class="slide-img"> <a href="slides[nowIndex].href" rel="external nofollow" > <transition name="slide-trans"> // 使用动画 <img v-if="isShow" :src="slides[nowIndex].src"> </transition> <transition name="slide-trans-old"> <img v-if="!isShow" :src="slides[nowIndex].src"> </transition> </a> </div> <h2>{{ slides[nowIndex].title }}</h2> <ul class="slide-pages"> <li @click="goto(prevIndex)"><</li> <li v-for="(item, index) in slides" @click="goto(index)"> <a :class="{ on: index === nowIndex}"> {{ index + 1 }} </a> </li> <li @click="goto(nextIndex)">></li> </ul> </div> </template> <script> export default { props: { slides: { // 获取父组件的属性 type: Array, default: [] }, inv: { type: Number, default: 1000 } }, data () { return { nowIndex: 0, isShow: true } }, computed: { prevIndex () { // 使用计算属性, if (this.nowIndex === 0) { return this.slides.length - 1 } else { return this.nowIndex - 1 } }, nextIndex () { if (this.nowIndex === this.slides.length - 1) { return 0 } else { return this.nowIndex + 1 } } }, methods: { goto (index) { this.isShow = false, setTimeout(() => { // 过10毫秒后, this.isShow = true, this.nowIndex = index }, 10) }, runInv () { // 设置定时器 this.timer = setInterval(() => { this.goto(this.nextIndex) }, this.inv) }, clearInv () { clearInterval(this.timer) } }, mounted () { // 加载完后执行 this.runInv() } } </script> <style scoped> .slide-trans-enter-active { transition: all .5s; } .slide-trans-enter { transform: translateX(900px); } .slide-trans-old-leave-active { transition: all .5s; transform: translateX(-900px); } .slide-show { position: relative; margin: 15px 15px 15px 0; width: 900px; height: 500px; overflow: hidden; } .slide-show h2 { position: absolute; width: 100%; height: 100%; color: #fff; background: #000; opacity: .5; bottom: 0; height: 30px; text-align: left; padding-left: 15px; } .slide-img { width: 100%; } .slide-img img { width: 100%; position: absolute; top: 0; } .slide-pages { position: absolute; bottom: 10px; right: 15px; } .slide-pages li { display: inline-block; padding: 0 10px; cursor: pointer; color: #fff; } .slide-pages li .on { text-decoration: underline; } </style>
希望本文所述对大家vue.js程序设计有所帮助。
