微信小程序实现购物商城（附源码）

2018年本人做了一个淘宝购物返利的微信公众号，截至目前已运营了近5年的时间，也陆续积累了不少粉丝。近日，有部分用户反馈是否可以在公众号上展示促销商品列表，而且要具备搜索功能。为感谢粉丝朋友们的长期支持，笔者耗时一周，利用茶余饭后时间，开发了一个微信小程序，详情如下：

一、首页

包括活动图片的轮播展示、活动商品缩略图和基本信息的展示、横向滑动tabBar、搜索框等。

<!--pdd_index.wxml-->
<import src="components/user_guide/user_guide"/>
<!--顶部搜素框-->
<view class="container">
  <view class="search">
    <view class="searchlong">
      <image class="searchico" src="/icon/search.jpeg"></image>
      <input class="searchkuang" type="text" placeholder="点击输入商品名称" confirm-type="search" bindconfirm="searchGoods" />
    </view>
  </view>

  <!--顶部轮播图-->
  <view class="luobotu">
    <swiper class="swiperImg" autoplay="{{autoplay}}" interval="{{interval}}" indicator-dots="true" circular="true" indicator-color="white" indicator-active-color="orange">

        data-itemId="{{item.itemId}}" data-imgUrl="{{item.imgUrl}}" data-jType="{{item.type}}" bindtap="jump_activity">
          <image class = "lunboimg" src="{{item.imgUrl}}"></image>
        </swiper-item>
      </block>
    </swiper>
  </view>

        <view class="nav-item {{currentTab == idx ?'active':''}}" data-current="{{idx}}" bindtap="switchNav" data-id="{{navItem.platIndex}}">
          <view>{{navItem.text}}</view>
          <view class="nav-line {{currentTab == idx ?'active':''}}"></view>
