vue 循環多個標簽，點擊標簽變色，再點擊取消，可以同時點擊多個

效果：

 

 

<div class="relFacilityTitcon">
          <i v-for="(item,index) in facilityList" :key="index" @click="changeSpan(index);" :class="{'bgcolor':spanIndex.indexOf(index)>-1}" >{{item}}</i>
</div>

 

 data:{

spanIndex:[],

}

methods: {
           
            changeSpan(index){
                let arrIndex = this.spanIndex.indexOf(index);
                // console.log(arrIndex);
                
                if(arrIndex>-1){
                    this.spanIndex.splice(arrIndex,1);
                }else{
                    this.spanIndex.push(index);
                }
            },
