1.效果
点击图片上方的car1,car2,car3下方的图片随着变动
2.代码的实现
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title></title>
<style type="text/css">
.tab ul {
overflow: hidden;
padding: 0;
margin: 0;
}
.tab ul li {
box-sizing: border-box;
padding: 0;
float: left;
width: 100px;
height: 45px;
line-height: 45px;
list-style: none;
text-align: center;
border-top: 1px solid blue;
border-right: 1px solid blue;
cursor
}
.tab ul li:first-child {
border-left: 1px solid blue;
}
.tab ul li.active {
background-color: orange;
}
.tab div {
width: 500px;
height: 300px;
display: none;
text-align: center;
font-size: 30px;
line-height: 300px;
border: 1px solid blue;
border-top: 0px;
}
.tab div.current {
display: block;
}
img{
width: 800px;
height: 500px;
}
</style>
<script type="text/javascript" src="../js/vue.min.js" ></script>
</head>
<body>
<div id="app">
<div class="tab">
<ul>
<li @click='change(index)' :class='currentIndex==index?"active":""' :key='item.id' v-for="(item,index) in list">{{item.title}}</li>
</ul>
<div :class='currentIndex==index?"current":""' :key='item.id' v-for='(item, index) in list'>
<img :src="item.path"/>
</div>
</div>
</div>
<script type="text/javascript">
new Vue({
el:'#app',
data:{
currentIndex: 0, // 选项卡当前的索引
list:[{
id:1,
title:'car1',
path:'img/car1.jpg'
},{
id:2,
title:'car2',
path:'img/car2.jpg',
},{
id:3,
title:'car3',
path:'img/car3.jpg'
}]
},
methods:{
change:function(index){
this.currentIndex=index;
}
}
})
</script>
</body>
</html>
3.注意的点：
设值选项卡的索引为currentIndex，然后每次点击让currentIndex的值=点击图片的index,这样就实现了点击的时候对应的样式改变同时图片也发生变化
要把问题进行分析，通过绑定或者事件给联系起来
