一.什么是flwx布局
- 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
<!--pages/vote/list/list.wxml--> <!-- <text>pages/vote/list/list.wxml</text> --> <!-- 投票管理 --> <view class="box"> <view>1</view> <view>2</view> <view>3</view> <view>4</view> <view>5</view> <view>6</view> <view>7</view> <view>8</view> <view>9</view> <view>10</view> <view>11</view> <view>12</view> </view>
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; }
二.flex属性
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
三.轮播图后台数据获取及组件使用
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
<!--index.wxml--> <view> <swiper indicator-dots="true" autoplay="true" > <block wx:for="{{imgSrcs}}" wx:key="*text"> <swiper-item> <image src=" {{item.img}}"></image> </swiper-item> </block> </swiper> </view>
测试结果
四.首页布局
在index.js中添加内容
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" } ]
在index.wxml中 将：
<view class="list-info"><text>{{item.address}}</text>|<text>{{item.time}}</text></view>
修改为：
<view class="list-info"><text>{{item.location}}</text>|<text>{{item.starttime}}</text></view>
在index.wxss中调试样式
/**index.wxss**/ .mobi-title{ background-color: green; padding: 10px; } .mobi-icon{ border: 1rpx solid red; margin-right: 5px; } .mobi-title text{ font-weight: 700; color: aqua; } .list{ display: flex; align-items: center; /* background-color: yellowgreen; */ border-bottom: 3px solid yellowgreen; } .list-img{ padding: 0 10px; } .video-img{ height: 80px; width: 80px; } .list-detail{ } .list-title{ font-weight: 700; margin: 3px 0; } .list-tag{ display: flex; align-items: center; } .state{ border: 2px solid red; padding: 3px 6px; color: red; margin:0 5px 10px 0; } .join{ color: yellowgreen; } .list-num{ color: aqua; font-weight: 700; } .list-info{ color: yellowgreen; font-size: 12px; }
