    先看一下今天要实现的小程序商品详情页吧!

    商品详情.gif

    本期我们要实现小程序商品详情页的头部标题、头部轮播、商品详情浮动按钮和商品内页布局。

    一、设置头部标题

    如上图所示,头部标题是商品详情 如果不进行设置的话会默认为app.json 设置的window.navigationBarTitleText值。

    detail.json
    {
      "navigationBarTitleText": "商品详情"
    }
    

    二、商品轮播

    如下图所示,商品详情页的商品轮播。

    detail.wxml
    <swiper indicator-dots="{{indicatorDots}}" autoplay="{{autoplay}}" interval="{{interval}}" duration="{{duration}}">
      <block wx:for="{{imgUrls}}">
        <swiper-item>
            <image src="{{item}}" data-src="{{item}}" bindtap="previewImage" mode="widthFix"></image>
        </swiper-item>
      </block>
    </swiper>
    
    detail.wxss
    page {
      display: flex;
      flex-direction: column;
      height: 100%;
    }
    /* 直接设置swiper属性 */
    swiper {
      /* height: 500rpx; */
        height: 600rpx;
        background: #F3F4F6;
        text-align: center;  
    }
    swiper-item image {
      width: 80%;
      height: 100%;
    }
    
    detail.js
    /**
       * 页面的初始数据
       */
      data: {
        // banner
        imgUrls: [
          "https://m.360buyimg.com/n12/jfs/t11317/108/1080677336/325163/f4c2a03a/59fd8b17Nbe2fcca3.jpg!q70.jpg",
          "https://m.360buyimg.com/n12/jfs/t11575/282/348533702/60173/d75cd1cc/59edb8d6N688b420f.jpg!q70.jpg",

          "https://m.360buyimg.com/n12/s750x750_jfs/t9733/126/2033941175/68120/a4eb4468/59edb8d6N37bea6f7.jpg!q70.jpg",

        ],
        indicatorDots: true, //是否显示面板指示点
        autoplay: true, //是否自动切换
        interval: 3000, //自动切换时间间隔,3s
        duration: 1000, //  滑动动画时长1s
    }
    

    三、商品详情浮动图标+商品描述

    detail.wxml
    <!--图文详情按钮-->
    <view class='tab-bar-detail'>
          <text>图文</text>
          <text>详情</text>
    </view> 
    
    <view class="product-price-wrap">
     <view>
        <p class="product-price-new">¥7935.84</p>  
        <p class="product-price-old">原价¥9018.00</p> 
        <p class="discount">8.8折</p>
      </view>
      <view>
        <image src="../../images/bottomNav/share.png" />  
      </view>   
    </view>
    <view class="product-name-wrap">
      <text>Apple iPhone X手机 苹果x 全网通4G 全面屏手机 银色 官方标配 256G</text>
    </view>
    
    detail.wxss
    /**图文详情 浮层**/
    .tab-bar-detail{
      width: 75rpx;
      height: 75rpx;
      background-color: #fff;
      border-radius:25px;
      position: fixed;  
      z-index: 2;
      right: 4%;
      top:500rpx;
      border:1rpx solid #F3F4F6; 
      line-height:25rpx; 
      text-align: center;  
      display: flex;
      flex-direction: column;
      justify-content: center;
    }
    .tab-bar-detail text{
      font-size: 22rpx;
      color: #e80080;
    }
    /**商品价格**/
    .product-price-wrap{
      display: flex;
      justify-content:space-between;/**两边对齐**/
      flex-direction: row;
      flex-wrap: wrap;
      margin:5px 5px;
       /* border:1rpx solid red;   */
    }
     .product-price-wrap .product-price-new{
      color: #e80080;
      font-weight:400;
      font-size: 24px;
    }
    .product-price-wrap .product-price-old{
      color: #888;
      text-decoration: line-through;
      padding-left: 5px;
      font-size: 14px;
      line-height:30px;
      font-weight:300;
    }
    .product-price-wrap .discount{
      margin: 5px 5px;
      background-color: #000;
      color: #fff;
      height: 18px;
      font-size: 14px;
      border-radius:2px;
    } 
    .product-price-wrap image{
      width:40rpx;
      height: 40rpx;
      margin: 5px 5px; 
    }
    .product-name-wrap{
      margin: 0px 10px;
       /* border:1rpx solid red;  */
    }
    .product-name-wrap text{
      font-size: 14px;
      font-weight:400;
      line-height: .48rem;
      color: #404040;
    }
    

    四、商品内页详情

    detail.wxml
    <view class="details"> 
       <scroll-view scroll-y="true"> 
           <block wx:for-items="{{detailImg}}" wx:key="name">
           <image class="image_detail" src="{{item}}" mode="widthFix"/> 
        </block>  
       </scroll-view> 
     </view> 
    
    detail.wxss
    .details{
       padding: 0px 5px 0 5px; 
    }
    .detail {
      display: flex;
      flex-direction: column;
      margin-top: 15rpx;
      margin-bottom: 0rpx;
    }
