一.前言
今天终于进入正轨了,正式使用小程序制作一款App,本专栏以会议OA为示例进行讲解。本文章首先来实现OA的首页
二.flex弹性布局
学习地址:
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。
flex属性
- flex-direction 主轴的方向 默认为row
- 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
- align-content 属性定义了多根轴线的对齐方式
注意,设为Flex布局以后,子元素的float、clear和vertical-align属性将失效。
2.1 display: flex 弹性布局属性
前端代码:
<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>
样式添加:
给每一个view设置了宽高为100rpx,众所周知小程序的手机端的宽度是750rpx
.box{ height: 750rpx; width: 750rpx; background-color: pink; display: flex; } view{ height: 100rpx; width: 100rpx; border: 1px solid greenyellow; }
添加display: flex之前与之后的对比:
2.2 flex-direction属性
flex-direction属性决定主轴的方向(即项目的排列方向)。
flex-direction: row | row-reverse | column | column-reverse;
2.3 flex-wrap属性
默认情况下,项目都排在一条线(又称”轴线”)上。flex-wrap属性定义,如果一条轴线排不下,如何换行。
flex-wrap: nowrap (不换行) | wrap | wrap-reverse;
2.4 flex-flow属性
flex-flow属性是flex-direction属性和flex-wrap属性的简写形式,就是将两者结合起来了,默认值为row nowrap。
2.5 justify-content属性
justify-content: flex-start(居右对齐) | flex-end(居左对齐) | center(居中对齐) | space-between(两端对齐,项目之间的间隔都相等) | space-around(每个项目两侧的间隔相等。所以,项目之间的间隔比项目与边框的间隔大一倍。)
三.首页轮播图
3.1 我们先把一级菜单底座打好
在app.json里面:
"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" }] },
3.2 mockJS模拟数据
定义接口:
右击新建立一个文件夹:
在app.js里面定义接口 :
// 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 };
前端轮播图代码:index.wxml
这段代码是从官网拿的,里面的属性官网中可以看到:
<!--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>
样式:index.wxss
.swiper-item { height: 300rpx; width: 100%; border-radius: 10rpx; }
在index.js里面添加轮播图方法:
// 轮播图数据 loadSwiperImgs(){ let that=this; wx.request({ url: api.SwiperImgs, dataType: 'json', success(res) { console.log(res) that.setData({ imgSrcs:res.data.images }) } }) },
在index.js的onload方法中调用:
onLoad() { if (wx.getUserProfile) { this.setData({ canIUseGetUserProfile: true }) } this.loadSwiperImgs(); },
在index.js里面 接口mockjs
// 轮播图 mockjs const api = require("../config/app.js");
注意:在这里我们用的是http的网址,不是https所以会报错,我们需要修改
接着点开调式器的mock,在里面新增接口:
json数据:
{ "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" } }
这样就可以啦,看看效果
四.OA首页的布局
mock数据:
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" } ] },
前端index.wxml:
<view class="mobi-title"> <text class="mobi-icon"></text> <text>会议信息</text> </view> <block wx:for-items="{{lists}}" wx:for-item="item" wx:key="item.id"> <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 bottom-line"> <text>到底啦</text> </view>
样式:index.wxss
.mobi-title { font-size: 12pt; color: #777; line-height: 110%; font-weight: bold; width: 100%; padding: 15rpx; background-color: #f3f3f3; } .mobi-icon { padding: 0rpx 3rpx; border-radius: 3rpx; background-color: #ff7777; position: relative; margin-right: 10rpx; } /*list*/ .list { display: flex; flex-direction: row; width: 100%; padding: 0 20rpx 0 0; border-top: 1px solid #eeeeee; background-color: #fff; margin-bottom: 5rpx; /* border-radius: 20rpx; box-shadow: 0px 0px 10px 6px rgba(0,0,0,0.1); */ } .list-img { display: flex; margin: 10rpx 10rpx; width: 150rpx; height: 220rpx; justify-content: center; align-items: center; } .list-img .video-img { width: 120rpx; height: 120rpx; } .list-detail { margin: 10rpx 10rpx; display: flex; flex-direction: column; width: 600rpx; height: 220rpx; } .list-title text { font-size: 11pt; color: #333; font-weight: bold; } .list-detail .list-tag { display: flex; height: 70rpx; } .list-tag .state { font-size: 9pt; color: #81aaf7; width: 120rpx; border: 1px solid #93b9ff; border-radius: 2px; margin: 10rpx 0rpx; display: flex; justify-content: center; align-items: center; } .list-tag .join { font-size: 11pt; color: #bbb; margin-left: 20rpx; display: flex; justify-content: center; align-items: center; } .list-tag .list-num { font-size: 11pt; color: #ff6666; } .list-info { font-size: 9pt; color: #bbb; margin-top: 20rpx; } .bottom-line{ display: flex; height: 60rpx; justify-content: center; align-items: center; background-color: #f3f3f3; } .bottom-line text{ font-size: 9pt; color: #666; }
效果:
