上一篇还记得我们做了商品点击查看详情的事件采集吗？那么再加上跳转商品详情页功能，如下图所示：

detail.wxml

<swiper indicator-dots="{{indicatorDots}}" autoplay="{{autoplay}}" interval="{{interval}}" duration="{{duration}}">   <block wx:for="{{goods.imgUrls}}">     <swiper-item>       <image src="{{item}}" src="{{item}}" bindtap="previewImage" mode="widthFix"></image>     </swiper-item>   </block></swiper><!--商品价格和商品描述--><view><view class="product-name-wrap">     {{goods.title}}  </view>   <view class="product-price-wrap">       <view>         <p class="product-price-new">￥{{goods.price}}</p>           <p class="product-price-old">原价￥{{goods.privilegePrice}}</p>        </view>   </view></view>   <view class="details">    <scroll-view scroll-y="true">     <text>商品详情</text>     <block wx:for-items="{{goods.detailImg}}" wx:key="name">        <image class="image_detail" src="{{item}}" mode="widthFix"/>      </block>     <view class="temp"></view>   </scroll-view>  </view>
