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

Flex 布局语法教程 | 菜鸟教程网页布局(layout)是CSS的一个重点应用。 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。它对于那些特殊布局非常不方便,比如,垂直居中就不容易实现。 2009年,W3C提出了一种新的方案—-Flex布局,可以简便、完整、响应式地实现各种页面布局。目前,它已经得到了所有浏览器的支持,这意味着,现在就能很安全地使用这项功能。 Flex布局将成为未来布..
http://www.runoob.com/w3cnote/flex-grammar.html 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。
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:

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;




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;


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。
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。)
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"
- }]
- },

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:视图容器 / swiper (qq.com)
https://developers.weixin.qq.com/miniprogram/dev/component/swiper.html
- <!--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:
