用vue 的 v-for 實現按鈕選中改變樣式，且獲取對應值

<div class="vip-buy"> <div v-for="(item,index) in vipSet" :key="item.payprice" class="vip-buy-item" :class="{'select-item':index == clickIndex}" // 判斷當前點擊標簽 @touchstart="clickIndex = index" //記錄當前點擊標簽 @touchend="select(item.payprice)" //將對應值傳遞出去 > <p>{{item.length}}</p> <p>{{item.priceNow}}</p> <p class="del">{{item.priceLast}}</p> </div> </div> </div>
