首先在app.json中配置页面和底部tabbar

{
    "pages":[
        "pages/index/index",
        "pages/kind/kind",
        "pages/car/car",
        "pages/my/my" 
    ],
    "window":{
        "backgroundTextStyle": "dark",
        "navigationBarBackgroundColor": "#50a7e4",
        "navigationBarTitleText": "首页",
        "navigationBarTextStyle": "#fff",
        "enablePullDownRefresh": "true"
    },
    "tabBar": {
        "color": "#666",
        "selectedColor": "#41a5e5",
        "fontSize": "28rpx",
        "list": [
            {
                "pagePath": "pages/index/index",
                "text": "首页",
                "iconPath": "pages/images/home.png",
                "selectedIconPath": "pages/images/home_in.png"
            }, 
            {
                "pagePath": "pages/kind/kind",
                "text": "分类",
                "iconPath": "pages/images/kind.png",
                "selectedIconPath": "pages/images/kind_in.png"
            }, 
            {
                "pagePath": "pages/car/car",
                "text": "购物车",
                "iconPath": "pages/images/car.png",
                "selectedIconPath": "pages/images/car_in.png"
            }, 
            {
                "pagePath": "pages/my/my",
                "text": "我的",
                "iconPath": "pages/images/mine.png",
                "selectedIconPath": "pages/images/mine_in.png"
            }
        ]
    },
    "networkTimeout": {
        "request": 10000,
        "downloadFile": 10000
    },
    "debug": true
}

正式开始写代码了，首先是index.wxml

<scroll-view scroll-y="true">
    <!-- 轮播图部分开始  -->
    <view class="banner">
        <swiper indicator-dots="{{indicatorDots}}" autoplay="{{autoplay}}" interval="{{interval}}" duration="{{duration}}" indicator-color="rgba(228,228,228,1)" indicator-active-color="#FECA49">
            <block wx:for="{{imgUrls}}">
                <swiper-item>
                    <image src="{{item}}" class="slide-image" width="355" height="200" />
                </swiper-item>
            </block>
        </swiper>
    </view>
    <!-- 轮播图部分结束 -->
    <!-- 搜索部分开始 -->
    <view class="search" bindtap=\'search\'>
        <image src="../images/search.png"></image>
        <text>搜索商品</text>
    </view>
    <!-- 搜索部分结束 -->
    <!-- 特价列表开始 -->
    <view class="specialPrice">
        <view class="title">今日特价</view>
        <block wx:for="{{goodsList}}">
            <view class="goodsList">
                <image class="goodsPic" src=\'{{item.imgUrl}}\' bindtap=\'goToDetail\'></image>
                <view class="goodsInfo">
                    <view class="goodsTitle ellipsis2">{{item.title}}</view>
                    <view class="price">
                        <text class="fl newPrice">￥{{item.newPrice}}</text>
                        <text class="fl oldPrice">￥{{item.oldPrice}}</text>
                        <view>
                            <image class="fr car1" src=\'../images/car1.png\' bindtap=\'showCar\' data-id="{{item.id}}"></image>
                        </view>
                    </view>
                </view>
            </view>
        </block>
    </view>
    <!-- 特价列表结束 -->
</scroll-view>

接着index.wxss

.banner {
    width: 100%;
}

    height: 40rpx;
    margin: 0 10rpx;
}

.specialPrice {
    padding: 0 30rpx;
}

.title {
    margin: 20rpx 0;
    border-bottom: 1px solid #d8d8d8;
    padding-bottom: 10rpx;
    font-size: 36rpx;
    font-weight: bold;
}

.goodsList {
    padding: 20rpx;
    border-bottom: 1px solid #d8d8d8;
    display: -webkit-flex;
    display: flex;
}

.goodsList:last-child {
    border-bottom: none;
}

.goodsList .goodsPic {

    position: relative;
    flex: 1;
}

.goodsTitle {
    font-size: 32rpx;
    font-family: \'微软雅黑\';
}

.price {
    position: absolute;
    left: 20rpx;
    bottom: 0;
    width: 100%;
    display: -webkit-flex;
    display: flex;
    align-items: flex-end;
}

.price .newPrice {
    font-size: 36rpx;
    margin-top: 10rpx;
    margin-right: 10rpx;
}

.price .oldPrice {
    text-decoration: line-through;
    color: #d8d8d8;
    font-size: 28rpx;
    margin-top: 20rpx;
    align-items: -webkit-flex-end;
}

.price view {
    flex: 1;
}

.car1 {
    width: 56rpx;
    height: 56rpx;
    background: #50a7e4;
    border-radius: 50%;
}

最后是index.js

//index.js
//获取应用实例
var app = getApp()
Page({
    data: {
        hidden: true,
        count: \'1\',
        imgUrls: [

        ],
        indicatorDots: true,
        autoplay: false,
        interval: 5000,
        duration: 1000,
        goodsList: [

            {

                id: 600,
