1、实现效果
手机效果预览,这里的首页使用到了轮播图。页面图片数据可以替换成自己的数据。
2、开发者工具效果图
3、项目的目录结构
4、首页核心代码
4.1 index.js
这里用来存放数据,页面的数据。目前是假数据,也可以调用接口接收真实数据
// index.js
import { request } from '../../request/index'
Page({
data: {
//轮播图数组
swiperList: [

4.2 index.json
这里调用到了搜索框的组件,博客下方给出搜索框的相关代码
{
"usingComponents": {
"SearchInput": "../../components/SearchInput/SearchInput"
},
"navigationBarTitleText": "商品首页"
}
4.3 index.wxml
<!-- index.wxml -->
<view class="pyg_index">
<!-- 搜索框 开始 -->
<SearchInput></SearchInput>
<!-- 搜索框 结束 -->
<!-- 轮播图 开始 -->
<view class="index_swiper">
<swiper autoplay indicator-dots circular>
<swiper-item wx:for="{{swiperList}}" wx:key="id">
<navigator>
<image mode="widthFix" src="{{item.name}}"></image>
</navigator>

<!-- 轮播图 结束 -->

4.4 index.wxss
/**index.wxss**/
.index_swiper swiper {
width: 100%;
height: calc(100vm*352/1152);
}
.index_swiper image {
width: 100%;
}
.index_cate {
display: flex;
}

5、配置tabBar效果
app.json文件中文章来源:https://www.toymoban.com/news/detail-529107.html
{
"pages": [
"pages/index/index",
"pages/category/index",
"pages/cart/index",
"pages/user/index"
],
"requiredPrivateInfos": [
"choosePoi",
"chooseAddress"
],
"permission": {
"scope.userLocation": {
"desc": "你的位置信息将用来进行接口调试"
}
},
"window": {
"backgroundTextStyle": "light",
"navigationBarBackgroundColor": "#eb4450",
"navigationBarTitleText": "小郑优购",
"navigationBarTextStyle": "white"
},
"sitemapLocation": "sitemap.json",
"tabBar": {
"color": "#999",
"selectedColor": "#ff2d4a",
"backgroundColor": "#fafafa",
"position": "bottom",
"borderStyle": "black",
"list": [
{
"pagePath": "pages/index/index",
"text": "首页",
"iconPath": "icons/home.png",
"selectedIconPath": "icons/home_after.png"
},
{
"pagePath": "pages/category/index",
"text": "分类",
"iconPath": "icons/cateory.png",
"selectedIconPath": "icons/category_after.png"
},
{
"pagePath": "pages/cart/index",
"text": "购物车",
"iconPath": "icons/cart.png",
"selectedIconPath": "icons/cart_after.png"
},
{
"pagePath": "pages/user/index",
"text": "我的",
"iconPath": "icons/info.png",
"selectedIconPath": "icons/info_after.png"
}
]
}
}
6、搜索框组件
这里的js和json文件没用到,默认代码就行。如果不知道组件怎样创建,可以搜索以下,很容易实现。给出主要的布局和样式文章来源地址https://www.toymoban.com/news/detail-529107.html
6.1 SearchInput.wxml
<!--components/SearchInput/SearchInput.wxml-->
<view class="search_input">
<navigator url="/pages/search/index" open-type="navigate">
搜索
</navigator>
</view>
6.2 SearchInput.wxss
/* components/SearchInput/SearchInput.wxss */
.search_input {
height: 90rpx;
padding: 10rpx;
background-color: var(--themeColor);
}
.search_input navigator {
height: 100%;
display: flex;
justify-content: center;
align-items: center;
background-color: #fff;
border-radius: 15rpx;
color: #666;
}
