本文實例講述了vue.js實現的幻燈片功能。分享給大家供大家參考,具體如下:
1、在父組件中
<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"> // 當鼠標移入的時候清除,移出的時候 <div class="slide-img"> <a href="slides[nowIndex].href" rel="external nofollow" > <transition name="slide-trans"> // 使用動畫 <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: { // 獲取父組件的屬性 type: Array, default: [] }, inv: { type: Number, default: 1000 } }, data () { return { nowIndex: 0, isShow: true } }, computed: { prevIndex () { // 使用計算屬性, 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(() => { // 過10毫秒后, this.isShow = true, this.nowIndex = index }, 10) }, runInv () { // 設置定時器 this.timer = setInterval(() => { this.goto(this.nextIndex) }, this.inv) }, clearInv () { clearInterval(this.timer) } }, mounted () { // 加載完后執行 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>
希望本文所述對大家vue.js程序設計有所幫助。
