在公司手机端的vue编写中，需要用到一个轮播图，我一开始的时候使用的时候使用的是想在created中定义一个轮播函数，但是实际上这个轮播函数没有起作用，后面在网上看了一下，看到了网上的轮播图代码，是使用 transition-group来实现的，实践了一遍，现在代码如下：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<style>
*{
padding: 0;
margin: 0;
}
.carousel-wrap{
width: 600px;
position: relative;
margin: 0 auto;
}
.carousel {
position: relative;
height: 500px;
width: 600px;
background-color: #fff;
overflow: hidden;
}
.slide-ul {
width: 100%;
height: 100%;
}
li {
position: absolute;
width: 100%;
height: 100%;
}
img {
width: 100%;
height: 100%;
}
.list-enter-active {
transition: all 1s ease;
transform: translateX(0)
}
.list-leave-active {
transition: all 1s ease;
transform: translateX(-100%)
}
.list-enter {
transform: translateX(100%)
}
.list-leave {
transform: translateX(0)
}
.carousel-items{
position: absolute;
bottom: 10px;
margin:0 auto;
width: 100%;
text-align: center;
}
.circle{
display: inline-block;
width: 10px;
height: 10px;
border-radius: 100%;
border: 1px solid black;
margin: 0 10px;
}
.item-active{
background-color: whitesmoke;
}
</style>
</head>
<body>
<div id="carousel" class="carousel-wrap">
<div class="carousel">
<transition-group tag="ul" class="slide-ul" name="list">
<li v-for="(list,index) in slideList" :key="index" v-show="index===currentIndex" @mouseenter="stop" @mouseleave="go">
<a href="list.clickHref">
<img :src="list.img" :alt="list.desc">
</a>
</li>
</transition-group>
</div>
<div class="carousel-items">
<span v-for="(item,index) in slideList.length" class="circle" :class="{‘item-active‘:index===currentIndex}" @click="change(index)"></span>
</div>
</div>
<script src="vue.js"></script>
<script type="application/ecmascript">
new Vue({
el: "#carousel",
data:{
slideList: [
{
clickHref:"1",
img:"images/book5.jpg"
},
{
clickHref:"2",
img:"images/book6.jpg"
},
{
clickHref:"3",
img:"images/book7.jpg"
}
],
currentIndex:0,
timer:‘‘
},
methods:{
autoPlay:function(){
this.currentIndex++;
if (this.currentIndex > this.slideList.length - 1) {
this.currentIndex = 0
}
},
stop: function () {
clearInterval(this.timer);
this.timer=null;
},
go: function(){
this.timer=setInterval(()=>{
this.autoPlay()
},4000)
},
change: function(index){
this.currentIndex=index;
}
},
created(){
this.$nextTick(()=>{
this.timer=setInterval(()=>{
this.autoPlay()
},4000)
}
)
}
})
</script>
</body>
</html>
