<div class="weui-mask" id="guige">
 <div class="guigeBox">
 <p class="guigeTitle">{{guigeName}}</p>
 <p class="guigeP guigeP01">規(guī)格</p>
 <div class="indexGuiGe">
 <span v-for="value,index in guigeList" v-on:click="guige(index)" v-bind:class="{on:index==guigeSpan}">{{value.guige_name}}</span>
 </div>
 <p class="guigeP">口味</p>
 <div class="indexKouwie">
 <span v-for="value,index in kouweiList" v-on:click="kouwei(index)" v-bind:class="{on:index==kouweiSpan}">{{value.guige_name}}</span>
 </div>
 </div>
 </div>

var guige=new Vue({
 el: '#guige',
 data:{
 guigeSpan:"-1", //控制點亮狀態(tài) -1為默認(rèn)不點亮
 kouweiSpan:"-1", //控制點亮狀態(tài) 
 },
 methods:{
 guige:function(index){ //當(dāng)點擊時候點亮，同級的span標(biāo)簽刪除Class
 this.guigeSpan = index;
 },
 kouwei:function(index){
 this.kouweiSpan = index;
 },
 }
 })
