Flex是Flexible Box的缩写,意为”弹性布局”,用来为盒状模型提供最大的灵活性。
任何一个容器都可以指定为Flex布局。
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。
在app.json中编写 pages
- "pages":[
- "pages/index/index",
- "pages/meeting/list/list",
- "pages/vote/list/list",
- "pages/ucenter/index/index",
- "pages/logs/logs"
- ],
- "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"
- }]
- },
list.wxml中编写投票管理
"box"> -
1 2 3 4 5 6 7 8 9 10 11 12
在list.wxss中编写样式
- /* pages/vote/list/list.wxss */
- .box{
- height: 750rpx;
- width: 750rpx;
- background-color: aqua;
- display: flex;
- /* flex-direction: column; */
- /* flex-direction: column-reverse; */
- flex-wrap: wrap;
- /* flex-flow: row wrap; */
- /* justify-content: flex-end; */
- /* align-items: flex-end; */
- }
- view{
- height: 100rpx;
- width: 100rpx;
- border: 1px solid red;
- }
flex-direction 主轴的方向

flex-wrap 如果一条轴线排不下,如何换行
flex-flow 是flex-direction属性和flex-wrap属性的简写形式

justify-content 定义了项目在主轴上的对齐方式
align-items 定义项目在交叉轴上如何对齐

在app.js中编写url路径
- // 以下是业务服务器API地址
- // 本机开发API地址
- var WxApiRoot = 'http://localhost:8080/demo/wx/';
- // 测试环境部署api地址
- // var WxApiRoot = 'http://192.168.0.101:8070/demo/wx/';
- // 线上平台api地址
- //var WxApiRoot = 'https://www.oa-mini.com/demo/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
- };
在index.js中获取轮播图
- // 获取应用实例
- const app = getApp()
- const api=require("../../config/app.js")
- Page({
- data: {
- imgSrcs:[]
- },
- 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
- })
- }
- this.loadSwiperImgs();
- },
中途会报几个小错,使用Mock解决

Json数据包代码如下
- {
- "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"
- }
- }
在index.wxml中编写
-
"true" autoplay="true" > -
for="{{imgSrcs}}" wx:key="*text"> -
-
" {{item.img}}"> -
-
-
测试结果

在index.js中添加内容
- lists:[
- {
- "id": "1",
- "image": "/static/persons/1.jpg",

- ]
在index.wxml中 将:
"list-info">{{item.address}} |{{item.time}}
修改为:
"list-info">{{item.location}} |{{item.starttime}}
