上一篇：微信小程序电商实战-首页（上）

好了，上一期我们把首页搜索、导航栏和广告轮播给做完了，那么接下来会继续完成我们首页的剩余部分，先看我们要实现的效果吧！

微信小程序电商实战-首页（下）

本期我们要实现首页的实时热销榜、福利专场和左下方个人中心+购物车的布局。

一、实时热销榜

话不多说，先看实际效果图：

微信小程序电商实战-首页（下）

这个模块我们主要用到 scroll-view 视图容器，顾名思义就是滚动视图，当布局的内容超过屏幕容器的时候可以滑动开查看遮盖的内容，scroll-view可滚动视图区域属性详解：

scroll-x 允许横向滚动（类型：Boolean，默认值：false）
scroll-y 允许纵向滚动（类型：Boolean，默认值：false）
upper-threshold 距顶部/左边多远时（单位px），触发 scrolltoupper 事件（类型：Number，默认值：50）
lower-threshold 距底部/右边多远时（单位px），触发 scrolltolower 事件（类型：Number，默认值：50）
scroll-top 设置竖向滚动条位置（类型：Number）
scroll-left 设置横向滚动条位置（类型：Number）
scroll-into-view 值应为某子元素id（id不能以数字开头）。设置哪个方向可滚动，则在哪个方向滚动到该元素（类型：String）
scroll-with-animation 在设置滚动条位置时使用动画过渡（类型：Boolean，默认值：false）
更多请属性详情请查看微信官方scroll-view视图容器
