The content of this article is about the implementation code of the mall homepage carousel, product classification navigation and new product special sales developed by the WeChat mini-program mall. It has certain reference value. Friends in need can For reference, I hope it will be helpful to you.
Previous articleWe set up the https domain name setting of the mini program backend server, built the https framework based on the mini program and implemented the homepage navigation module. Let’s take a look at it today. Implementation of e-commerce home page carousel, category navigation and new product sale modules.
Mainly implement 2, 3, 4, API data services used As shown in the figure below:
<!--首页轮播 banner -->
<swiper indicator-dots="{{indicatorDots}}" autoplay="{{autoplay}}" interval="{{interval}}" duration="{{duration}}">
<block wx:for="{{banners}}">
<swiper-item>
<image src="{{item.imgUrl}}" mode="widthFix"/>
</swiper-item>
</block>
</swiper>/* 直接设置swiper属性 */
swiper {
height: 300rpx;
}
swiper-item image {
width: 100%; height: 100%;
