 <div class="labeloption" :class="{checked:ageActive == 11}" @click="changeStatus(11)">0-16岁</div>
 <div class="labeloption" :class="{checked:ageActive == 12}" @click="changeStatus(12)">17-25岁</div>
 <div class="labeloption" :class="{checked:ageActive == 13}" @click="changeStatus(13)">26-35岁</div>

 <div class="labeloption" :class="{checked:ageActive == 16}" @click="changeStatus(16)">55岁以上</div>

new Vue({
 el: '#home',
 data() {
 return {
 ageActive:11 //初始选中状态的元素id
 }
 },
 methods: {
 changeStatus(number){
 this.ageActive = number;
 }
 }
 })

<div class="labeloption checked" @click="changeStatus($event,11)">0-16岁</div>
<div class="labeloption" @click="changeStatus($event,12)">17-25岁</div>

<div class="labeloption" @click="changeStatus($event,15)">46-55岁</div>
<div class="labeloption" @click="changeStatus($event,16)">55岁以上</div>

new Vue({

 changeStatus(e,number){
 if (e.target.className.indexOf("checked") == -1) {
 e.target.className = "labeloption checked"; //选中div样式
