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.

Implementation of functional modules

Mainly implement 2, 3, 4, API data services used As shown in the figure below:

Home page carousel module implementation

home.js

<!--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>

home.wxss

/* 直接设置swiper属性 */
swiper {  
    height: 300rpx;
}
swiper-item image {  
    width: 100%;  height: 100%;
}

home.js

Page initialization carousel data

data: {
    navbars:null,//接上篇导航初始化数据
    currentTab: 0,//接上篇导航初始化数据
    banners:null,
    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
  },

Page initialization loading carousel data function

/**
   * 生命周期函数--监听页面加载
   */

onLoad: function (options) {    
    var that = this;    //加载navbar导航条，接上篇导航数据
    that.navbarShow();   //加载banner轮播
    that.bannerShow();
  },

ajax to obtain carousel data

bannerShow: function (success) {    
    var that = this;
    ajax.request({      
        method: 'GET',      
        url: 'home/banners?key=' + utils.key,      
        success: data => {
        that.setData({          
            banners: data.result
        })        
        console.log(data.result)
      }
    })
  },

Homepage classification navigation implementation

home.js

<!-- 分类导航 -->
 <view>
  <view class="navy">
    <block wx:for-items="{{menus}}" wx:key="name">
      <view class="nav-item"  data-type="{{item.menuName}}" data-typeid="{{item.id}}">
        <image src="{{item.imgUrl}}" class="nav-image" />
        <text>{{item.menuName}}</text>
      </view>
    </block>
  </view>
 </view>

    /* padding: 20rpx; */
    padding-top: 20rpx;
}
.nav-item .nav-image {  
    width: 80rpx;  
    height: 80rpx;  /* border-radius: 50%;设置边界圆角 */
}
.nav-item text {  
    padding-top: 20rpx;  
    font-size: 25rpx;
}

home.js

页面初始化分类导航数据

    interval: 3000, //自动切换时间间隔,3s
    duration: 1000, //  滑动动画时长1s
    menus: null, //分类导航数据},

页面初始化加载分类导航数据函数

/**
   * 生命周期函数--监听页面加载
   */
  onLoad: function (options) {    
    var that = this;    //加载navbar导航条
    that.navbarShow();    //加载banner轮播
    that.bannerShow();    //加载menu分类导航菜单

    ajax.request({      
    method: 'GET',      
    url: 'home/menus?key='+ utils.key,      
    success: data => {
        that.setData({          
            menus: data.result
        })        
        console.log(data.result)
      }
    })
  },

首页新品特卖模块实现

}

home.js

页面初始化新品特卖数据

data: {
    navbars:null,//导航数据
    currentTab: 0,
    banners:null, //轮播数据
    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
    menus: null, //分类导航数据
    brands: null, //新品特卖数据},

页面初始化加载新品特卖数据函数

/**
   * 生命周期函数--监听页面加载
   */
  onLoad: function (options) {    
    var that = this;    //加载navbar导航条
    that.navbarShow();    //加载banner轮播
    that.bannerShow();    //加载menu分类导航菜单
    that.menuShow();   //加载新品特卖
    that.brandShow();
  },

ajax获取新品特卖数据

brandShow: function (success) {    
var that = this;

            brands: data.result.list
        })        
            console.log("brands：" + data.result.list)
      }
    })
  },
