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/jfs/t11536/279/360605865/15194/442cab0b/59edb8d3N163a7608.jpg!q70.jpg",
      "https://m.360buyimg.com/n12/s750x750_jfs/t9733/126/2033941175/68120/a4eb4468/59edb8d6N37bea6f7.jpg!q70.jpg",
      "https://m.360buyimg.com/n12/s750x750_jfs/t10744/195/2053933852/71608/94425578/59edb8d6Ne28c70ff.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;
}
detail.js
// 商品详情介绍
    detailImg: [

总结

在做商品图文详情页图片布局的时候遇到了问题，图片加载会不自然 并且比较模糊，具体处理方法可以参考另一篇文章微信小程序-Image 图片实现宽度100%，高度自适应。
