上一篇：微信小程序电商实战-首页（下）
先看一下今天要实现的小程序商品详情页吧！
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",

],
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

五、效果图
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。
