<style>
.tab-warp{
border-bottom: solid 1px #e0e0e0;
overflow: hidden;
margin-top: 30px;
position: relative;
z-index: 1;
}
.tab-item{
float: left;
height: 34px;
line-height: 32px;
padding: 0 20px;
border-radius: 3px 3px 0 0;
position: relative;
z-index: 4;
border: solid 1px transparent;
transition: border .5s, color .3s;
cursor: pointer;
}
.tab-item.selected{
border-color: #e0e0e0 #e0e0e0 transparent;
color: #2d8cf0;
}
</style>
<template>
<div class="tab-warp">
<div class="tab-item" :class="{selected:index == indexCur}" v-for="(item, index) in info.tabInfo"
@click="setCategory(item,index)">{{item.categoryName}}
</div>
</div>
</template>
<script>
export default () {
data(){
return {
indexCur: 0
}
},
mathods:{
setCategory (item,index) {
this.indexCur = index;
},
}
}
</script>
效果圖:
注:當 index == indexCur 時纔會添加selected類,template中有些內容是接口獲取來的可沒必要理會
