使用vue实现多规格选择实例（SKU）

<template>
  <div class="wrap wrap-sku">
    <div class="product-box">
      <div class="product-content">
        <div class="product-delcom" v-for="(ProductItem,n) in simulatedDATA.specifications">
          <p>{{ProductItem.name}}</p>
          <ul class="product-footerlist clearfix">
            <li v-for="(oItem,index) in ProductItem.item"
              v-on:click="specificationBtn(oItem.name,n,$event,index)"
              v-bind:class="[oItem.isShow">
              {{oItem.name}}
            </li>
          </ul>
        </div>
        <p v-if="price" class="price">¥{{price}}</p>
      </div>
      <div class="product-footer">
        <a href="javascript:" rel="external nofollow" >立即购买</a>
      </div>
    </div>
  </div>
</template>
