布局的传统解决方案,基于盒状模型,依赖 display属性 + position属性 + float属性
容器默认存在两根轴:水平的主轴(main axis)和垂直的交叉轴(cross axis)。主轴的开始位置(与边框的交叉点)叫做main start,结束位置叫做main end;交叉轴的开始位置叫做cross start,结束位置叫做cross end。
项目默认沿主轴排列。单个项目占据的主轴空间叫做main size,占据的交叉轴空间叫做cross size。
注意,设为Flex布局以后,子元素的float、clear和vertical-align属性将失效。

在该项目资源管理器创建以下路径,用来存放图标:
/static/tabBar/coding-active.png
创建新的小程序项目之后,在app.json里面pages新建页面和绑定tabBer。
- {
- "pages": [
- "pages/index/index",
- "pages/meeting/list/list",
- "pages/vote/list/list",
- "pages/ucenter/index/index",
- "pages/logs/logs"
- ],
- "window": {
- "backgroundTextStyle": "light",
- "navigationBarBackgroundColor": "#fff",
- "navigationBarTitleText": "Weixin",
- "navigationBarTextStyle": "black"
- },
- "tabBar": {
- "list": [
- {
- "pagePath": "pages/index/index",
- "text": "首页",
- "iconPath": "/static/tabBar/coding.png",
- "selectedIconPath": "/static/tabBar/coding-active.png"
- },
- {
- "pagePath": "pages/meeting/list/list",
- "iconPath": "/static/tabBar/sdk.png",
- "selectedIconPath": "/static/tabBar/sdk-active.png",
- "text": "会议"
- },
- {
- "pagePath": "pages/vote/list/list",
- "iconPath": "/static/tabBar/template.png",
- "selectedIconPath": "/static/tabBar/template-active.png",
- "text": "投票"
- },
- {
- "pagePath": "pages/ucenter/index/index",
- "iconPath": "/static/tabBar/component.png",
- "selectedIconPath": "/static/tabBar/component-active.png",
- "text": "设置"
- }
- ]
- },
- "style": "v2",
- "sitemapLocation": "sitemap.json"
- }
在该项目资源管理器创建config/api.js文件
- // 以下是业务服务器API地址
- // 本机开发API地址
- var WxApiRoot = 'http://localhost:8080/ycxw/wx/';
- // 测试环境部署api地址
- // var WxApiRoot = 'http://192.168.0.101:8070/ycxw/wx/';
- // 线上平台api地址
- //var WxApiRoot = 'https://www.oa-mini.com/ycxw/wx/';
-
- module.exports = {
- IndexUrl: WxApiRoot + 'home/index', //首页数据接口
- SwiperImgs: WxApiRoot+'swiperImgs', //轮播图
- MettingInfos: WxApiRoot+'meeting/list', //会议信息
- };
本次没有连接后端,利用小程序Mock模拟假数据。
打开调试器,按照一下示例进行操作
- {
- "data": {
- "images":[
- {
- "img": "https://cdn-we-retail.ym.tencent.com/tsr/home/v2/banner1.png",
- "text": "1"
- },
- {
- "img": "https://cdn-we-retail.ym.tencent.com/tsr/home/v2/banner2.png",
- "text": "2"
- },
- {
- "img": "https://cdn-we-retail.ym.tencent.com/tsr/home/v2/banner3.png",
- "text": "3"
- },
- {
- "img": "https://cdn-we-retail.ym.tencent.com/tsr/home/v2/banner4.png",
- "text": "4"
- },
- {
- "img": "https://cdn-we-retail.ym.tencent.com/tsr/home/v2/banner5.png",
- "text": "5"
- },
- {
- "img": "https://cdn-we-retail.ym.tencent.com/tsr/home/v2/banner6.png",
- "text": "6"
- }
- ]
- },
- "statusCode": "200",
- "header": {
- "content-type":"applicaiton/json;charset=utf-8"
- }
- }
首先打开不校验合法域名设置:
编写轮播图页面:
//index.wxml <view> <swiper autoplay="true" indicator-dots="true" indicator-color="#fff" indicator-active-color="#00f"> <block wx:for="{{imgSrcs}}" wx:key="text"> <swiper-item> <view> <image src="{{item.img}}" class="swiper-item" /> </view> </swiper-item> </block> </swiper> </view>编写js
// index.js // 获取应用实例 const app = getApp() const api = require("../../config/api") Page({ data: { imgSrcs: [], lists: [] }, // 事件处理函数 bindViewTap() { wx.navigateTo({ url: '../logs/logs' }) }, // 轮播图的方法 loadSwiperImgs() { let that = this; wx.request({ url: api.SwiperImgs, dataType: 'json', success(res) { console.log(res) that.setData({ imgSrcs: res.data.images }) } }) }, onLoad() { if (wx.getUserProfile) { this.setData({ canIUseGetUserProfile: true }) } // 一进来就调用轮播图的方法 this.loadSwiperImgs(); this.loadMeetingInfos(); }, getUserProfile(e) { // 推荐使用wx.getUserProfile获取用户信息,开发者每次通过该接口获取用户个人信息均需用户确认,开发者妥善保管用户快速填写的头像昵称,避免重复弹窗 wx.getUserProfile({ desc: '展示用户信息', // 声明获取用户个人信息后的用途,后续会展示在弹窗中,请谨慎填写 success: (res) => { console.log(res) this.setData({ userInfo: res.userInfo, hasUserInfo: true }) } }) }, getUserInfo(e) { // 不推荐使用getUserInfo获取用户信息,预计自2021年4月13日起,getUserInfo将不再弹出弹窗,并直接返回匿名的用户个人信息 console.log(e) this.setData({ userInfo: e.detail.userInfo, hasUserInfo: true }) } })效果图:
1. 利用Mack模拟数据
JSON数据包:
{ "data": { "lists": [ { "id": "1", "image": "/static/persons/1.jpg", "title": "对话产品总监 | 深圳·北京PM大会 【深度对话小米/京东/等产品总监】", "num":"304", "state":"进行中", "starttime": "2022-03-13 00:00:00", "location": "深圳市·南山区" }, { "id": "1", "image": "/static/persons/2.jpg", "title": "AI WORLD 2016世界人工智能大会", "num":"380", "state":"已结束", "starttime": "2022-03-15 00:00:00", "location": "北京市·朝阳区" }, { "id": "1", "image": "/static/persons/3.jpg", "title": "H100太空商业大会", "num":"500", "state":"进行中", "starttime": "2022-03-13 00:00:00", "location": "大连市" }, { "id": "1", "image": "/static/persons/4.jpg", "title": "报名年度盛事,大咖云集!2016凤凰国际论坛邀您“与世界对话”", "num":"150", "state":"已结束", "starttime": "2022-03-13 00:00:00", "location": "北京市·朝阳区" }, { "id": "1", "image": "/static/persons/5.jpg", "title": "新质生活 · 品质时代 2016消费升级创新大会", "num":"217", "state":"进行中", "starttime": "2022-03-13 00:00:00", "location": "北京市·朝阳区" } ] }, "statusCode": "200", "header": { "content-type":"applicaiton/json;charset=utf-8" } }
2. 添加js方法
- index.js
- //首页会议信息的ajax
- loadMeetingInfos() {
- let that = this;
- wx.request({
- url: api.MettingInfos,
- dataType: 'json',
- success(res) {
- console.log(res),
- that.setData({
- lists: res.data.lists
- })
- }
- })
- },
3. 首页界面:
- <view class="indexbg">
- <swiper autoplay="true" indicator-dots="true" indicator-color="#fff" indicator-active-color="#00f">
- <block wx:for="{{imgSrcs}}" wx:key="text">
- <swiper-item>
- <view>
- <image src="{{item.img}}" class="swiper-item" />
- </view>
- </swiper-item>
- </block>
- </swiper>
- <view class="mobi-title">
- <text class="mobi-text">会议信息</text>
- </view>
- <block wx:for-items="{{lists}}" wx:for-item="item" wx:key="item.id" class="bg">
- <view class="list" data-id="{{item.id}}">
- <view class="list-img">
- <image class="video-img" mode="scaleToFill" src="{{item.image}}"></image>
- </view>
- <view class="list-detail">
- <view class="list-title"><text>{{item.title}}</text></view>
- <view class="list-tag">
- <view class="state">{{item.state}}</view>
- <view class="join"><text class="list-num">{{item.num}}</text>人报名</view>
- </view>
- <view class="list-info"><text>{{item.location}}</text>|<text>{{item.starttime}}</text></view>
- </view>
- </view>
- </block>
- <view class="section">

- </view>
- </view>
