vue动态获取ref方式

 <div v-for="(item,index) in list" :key="index"
             :class=" circleAnimation === 1 ? 'ball ball'+ (index+1) : 'ball ball1'+(index+1)" ref="circle" @click="oneClick(index)">
            <div>{{item.name}}</div>
        </div>

   oneClick(index) {
                if (index !== 2) {
                    this.circleAnimation = 1
                    const ref = this.$refs.circle[index].style
                }
            }
