react实战 系列
上一篇我们在 spug 项目中模仿”任务计划“模块实现一个类似的一级导航页面（”My任务计划“），本篇，我们将模仿“Dashboard”来实现一个仪表盘“My Dashboard”。
主要涉及 antd 的 Grid、Card、Descriptions等组件、bizcharts 的使用、moment 日期库和页面适配。
注：实现的代码在上一篇的基础上展开。
Dashboard界面如下：
里面用到了：
- antd 的
Grid、Card、Descriptions描述列表 （文字长度不同，有时会感觉没对齐） bizcharts中的折线图、柱状图moment（日期相关的库），比如按天、按月、最近 30 天都很方便
无需权限即可访问：
全屏效果：
@antv/data-set，柱状图和饼状图需要使用bx-tooltip，自定义 bizcharts 中的 tooltip。折线图和柱状图的 tooltip 都使用了。

package.json 变动如下：
"dependencies": {
"@antv/data-set": "^0.11.8",
}
"devDependencies": {
"bx-tooltip": "^0.1.6",
}
spug 中封装的表格组件，不支持 style和 size。替换一行，以及增加一行：
// src/components/TableCard.js
- <div ref={rootRef} className={styles.tableCard}>
+ <div ref={rootRef} className={styles.tableCard} style={{...props.customStyles}}>
<Table
+ size={props.size}
将 mydashboard 模块的的 mock 专门放入一个文件，并在 mock/index.js 中引入。
// src\mock\index.js
+ import './mydashboard'
// src\mock\mydashboard.js
import Mock from 'mockjs'
// 开发环境引入 mock
if (process.env.NODE_ENV === 'development') {
Mock.mock('/api/mdashboard/occupancy_rate/', 'get', () => (
{"data": [ {
month: "2022-01-01",
city: "城市-名字很长很长很长",
happiness: 10,
per: 90,
msg1: '信息xxx'
},
{
month: "2022-01-01",
city: "城市B",
per: 30,
happiness: 50,
msg1: '信息xxx'
},
{
month: "2022-02-01",
city: "城市-名字很长很长很长",
happiness: 20,
per: 40,
msg1: '信息xxx'
},
{
month: "2022-02-01",
city: "城市B",
happiness: 20,
per: 60,
msg1: '信息xxx'
},
{
month: "2022-03-01",
city: "城市-名字很长很长很长",
happiness: 30,
per: 80,
msg1: '信息xxx'
},], "error": ""}
))
let mIdSeed = 1;
Mock.mock('/api/mdashboard/table', 'get', () => ({
"data": [{ "id": mIdSeed++, "name": "苹果" + mIdSeed, address: '场地' +mIdSeed, time: new Date().toLocaleTimeString() },
{ "id": mIdSeed++, "name": "苹果" + mIdSeed, address: '场地' +mIdSeed, time: new Date().toLocaleTimeString() },
{ "id": mIdSeed++, "name": "苹果" + mIdSeed, address: '场地' +mIdSeed, time: new Date().toLocaleTimeString() },
{ "id": mIdSeed++, "name": "苹果" + mIdSeed, address: '场地' +mIdSeed, time: new Date().toLocaleTimeString() },
{ "id": mIdSeed++, "name": "苹果" + mIdSeed, address: '场地' +mIdSeed, time: new Date().toLocaleTimeString() },
{ "id": mIdSeed++, "name": "苹果" + mIdSeed, address: '场地' +mIdSeed, time: new Date().toLocaleTimeString() },
{ "id": mIdSeed++, "name": "苹果" + mIdSeed, address: '场地' +mIdSeed, time: new Date().toLocaleTimeString() },

{ "id": mIdSeed++, "name": "苹果" + mIdSeed, address: '场地' +mIdSeed, time: new Date().toLocaleTimeString() },
]
}))
}
配置 /mdashboard 和 /mydashboard 两个路由：
// src\App.js
+ import MDashboard from './pages/mdashboard/tIndex';
class App extends Component {
render() {
return (
<Switch>
// 无需权限
+ <Route path="/mdashboard" exact component={MDashboard} />
<Route path="/" exact component={Login} />
<Route path="/ssh" exact component={WebSSH} />
<Route component={Layout} />
</Switch>
);
}
}
// src\routes.js
+ import MyDashboardIndex from './pages/mdashboard';
export default [
{icon: <DesktopOutlined/>, title: '工作台', path: '/home', component: HomeIndex},
{
icon: <DashboardOutlined/>,
title: 'Dashboard',
auth: 'dashboard.dashboard.view',
path: '/dashboard',
component: DashboardIndex
},
+ // 我的仪表盘
+ {
+ icon: <DashboardOutlined />,
+ title: 'MyDashboard',
+ auth: 'mydashboard.mydashboard.view',
+ path: '/mydashboard',
+ component: MyDashboardIndex
+ },
新建仪表盘组件。一个需要权限访问，另一个无需权限即可访问，故将仪表盘提取成一个单独的文件：
// src\pages\mdashboard\Dashboard.js
import React from 'react';
export default function () {
return (
<div>仪表盘</div>
)
}
// src\pages\mdashboard\index.js
import React from 'react';
import { AuthDiv } from 'components';
import Dashboard from './Dashboard';
export default function () {
return (
<section>
// AuthDiv 是 spug 封装的与权限相关的组件
<AuthDiv auth="testdashboard.testdashboard.view">
<p>需要权限才能访问</p>
<Dashboard />
</AuthDiv>
</section>
)
}
// src\pages\mdashboard\tIndex.js
import React from 'react';
import Dashboard from './Dashboard';
export default function () {
return (
<section>
<p>无需权限也能访问</p>
<Dashboard />
</section>
)
}
重启服务，倘若能访问，说明一切就绪，只差仪表盘核心代码。
访问 /mydashboard：
访问 /mdashboard：

重启服务，效果如下：
bizcharts 是阿里的一个图表组件库。
注：spug 项目中使用的版本是 3.x。参考文档时不要搞错。
上面我们安装的其中一个依赖包 bx-tooltip 就来自这里。
实战其实就是一些 bizcharts 使用上的一些答疑。例如“内容显示不完整”，有可能就是因为 padding 的原因。
例如我们使用的堆叠柱状图的用法示例就参考这里：
点击进入示例，修改左边源码，右侧显示也会同步，非常方便我们在线研究和学习：
bizcharts 有宽度自适应，但没有实现高度的自适应。
笔者高度自适应的做法：将高度全部改为百分比。
具体做法如下：
- 由于没有设计，故先用固定像素实现界面
- 取得浏览器的窗口高度 window.innerHeight，笔者这里是 937
- 将“标签盒子”、“卡片头部高度”、卡片 body 部分等全部改为百分比
核心代码如下：
// src\pages\mdashboard\store.js
const PADDING = 16
class Store {
@observable baseBoxHeight = 937 - PADDING
@observable padding = PADDING
// 仪表盘盒子高度
@observable boxHeight = window.innerHeight - this.padding * 2
// 饼图高度比例。根据之前的效果算出来的
@observable pieBoxRatio = 0.20
// 柱状图高度比例
@observable barBoxRatio = 0.23
// “My Dashboard 我的仪表盘” 高度
@computed get TitleHeight() {
const ratio = 80 / this.baseBoxHeight
return this.boxHeight * ratio
}
// 运行card高度
@computed get todayCardHeight() {
const ratio = 75 / this.baseBoxHeight
return this.boxHeight * ratio
}
// “饼图+描述列表+柱状图” body 高度
@computed get statisticBodyHeight() {
const ratio = 660 / this.baseBoxHeight
return this.boxHeight * ratio
}
// 居住趋势 body 的高度
@computed get trendBodyBodyHeight() {
const ratio = 385 / this.baseBoxHeight
return this.boxHeight * ratio
}
// xys16 得用 computed 才会联动。下面这种写法不会联动
@computed get xys16() {
return (16 / this.baseBoxHeight) * this.boxHeight
}
// 饼状图盒子高度
@computed get pieBoxHeight() {
return this.pieBoxRatio * this.boxHeight
}
// card 的 header 比例
@computed get cardTitleStyle() {
const cardTitleRatio = 57 / this.baseBoxHeight
return { display: 'flex', height: this.boxHeight * cardTitleRatio, alignItems: 'center', justifyContent: 'center' }
}
}
实现过程中出现如下两个问题：一个是折线图的 Y 轴乱序，一个是堆叠柱状图有一节空白。
原因是值不小心弄成了字符串，改为数字类型即可。
