春天到了，各种绚丽的花朵都开放了，金黄的油菜花，成了蝴蝶的天地，美丽的蝴蝶在金黄色的舞台上跳着柔和而优美的舞姿。它们一会儿在空中飞舞，一会儿静静地停留在油菜花上。给春天增添了不少乐趣。油菜花的美丽，同时也吸引了不少 "劳动人民 "——蜜蜂，它们总是不分昼夜地不辞辛劳地给油菜花授粉。偶尔一阵微风吹来，金黄的油菜花立刻涌起了高低起伏的 "金浪花 "。远远望去，真是美不胜收！
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 rel="nofollow noopener noreferrer" 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 {

}
.slide-show {
position: relative;
margin: 15px 15px 15px 0;
width: 900px;
height: 500px;
overflow: hidden;
}
.slide-show h2 {

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;

}
.slide-pages li .on {
text-decoration: underline;

</style>
