spug 中封裝得表格組件，不支持 style和 size。替換一行，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}準(zhǔn)備 mock 數(shù)據(jù)

將 mydashboard 模塊得得 mock 專門放入一個(gè)文件，并在 mock/index.js 中引入。

// src\mock\index.js+ import './mydashboard'

// src\mock\mydashboard.jsimport Mock from 'mockjs'// 開發(fā)環(huán)境引入 mockif (process.env.NODE_ENV === 'development') { Mock.mock('/api/mdashboard/occupancy_rate/', 'get', () => ( {"data": [ { month: "2022-01-01", city: "城市-名字很長很長很長", 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-名字很長很長很長", 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-名字很長很長很長", happiness: 30, per: 80, msg1: '信息xxx' },], "error": ""}))let mIdSeed = 1;Mock.mock('/api/mdashboard/table', 'get', () => ({ "data": [{ "id": mIdSeed++, "name": "蘋果" + mIdSeed, address: '場地' +mIdSeed, time: new Date().toLocaleTimeString() }, { "id": mIdSeed++, "name": "蘋果" + mIdSeed, address: '場地' +mIdSeed, time: new Date().toLocaleTimeString() }, { "id": mIdSeed++, "name": "蘋果" + mIdSeed, address: '場地' +mIdSeed, time: new Date().toLocaleTimeString() }, { "id": mIdSeed++, "name": "蘋果" + mIdSeed, address: '場地' +mIdSeed, time: new Date().toLocaleTimeString() }, { "id": mIdSeed++, "name": "蘋果" + mIdSeed, address: '場地' +mIdSeed, time: new Date().toLocaleTimeString() }, { "id": mIdSeed++, "name": "蘋果" + mIdSeed, address: '場地' +mIdSeed, time: new Date().toLocaleTimeString() }, { "id": mIdSeed++, "name": "蘋果" + mIdSeed, address: '場地' +mIdSeed, time: new Date().toLocaleTimeString() }, { "id": mIdSeed++, "name": "蘋果" + mIdSeed, address: '場地' +mIdSeed, time: new Date().toLocaleTimeString() }, { "id": mIdSeed++, "name": "蘋果" + mIdSeed, address: '場地' +mIdSeed, time: new Date().toLocaleTimeString() }, { "id": mIdSeed++, "name": "蘋果" + mIdSeed, address: '場地' +mIdSeed, time: new Date().toLocaleTimeString() }, { "id": mIdSeed++, "name": "蘋果" + mIdSeed, address: '場地' +mIdSeed, time: new Date().toLocaleTimeString() }, { "id": mIdSeed++, "name": "蘋果" + mIdSeed, address: '場地' +mIdSeed, time: new Date().toLocaleTimeString() }, { "id": mIdSeed++, "name": "蘋果" + mIdSeed, address: '場地' +mIdSeed, time: new Date().toLocaleTimeString() }, { "id": mIdSeed++, "name": "蘋果" + mIdSeed, address: '場地' +mIdSeed, time: new Date().toLocaleTimeString() },]}))}路由配置

配置 /mdashboard 和 /mydashboard 兩個(gè)路由：

// src\App.js+ import MDashboard from './pages/mdashboard/tIndex';class App extends Component { render() { return ( <Switch> // 無需權(quán)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: '工作臺', path: '/home', component: HomeIndex}, { icon: <DashboardOutlined/>, title: 'Dashboard', auth: 'dashboard.dashboard.view', path: '/dashboard', component: DashboardIndex },+ // 我得儀表盤+ {+ icon: <DashboardOutlined />,+ title: 'MyDashboard',+ auth: 'mydashboard.mydashboard.view',+ path: '/mydashboard',+ component: MyDashboardIndex+ },

新建儀表盤組件。一個(gè)需要權(quán)限訪問，另一個(gè)無需權(quán)限即可訪問，故將儀表盤提取成一個(gè)單獨(dú)得文件：

// src\pages\mdashboard\Dashboard.jsimport React from 'react';export default function () { return ( <div>儀表盤</div> )}

// src\pages\mdashboard\index.jsimport React from 'react';import { AuthDiv } from 'components';import Dashboard from './Dashboard';export default function () { return ( <section> // AuthDiv 是 spug 封裝得與權(quán)限相關(guān)得組件 <AuthDiv auth="testdashboard.testdashboard.view"> <p>需要權(quán)限才能訪問</p> <Dashboard /> </AuthDiv> </section> )}

// src\pages\mdashboard\tIndex.jsimport React from 'react';import Dashboard from './Dashboard';export default function () { return ( <section> <p>無需權(quán)限也能訪問</p> <Dashboard /> </section> )}

重啟服務(wù)，倘若能訪問，說明一切就緒，只差儀表盤核心代碼。

重啟服務(wù)，效果如下：

bizcharts 是阿里得一個(gè)圖表組件庫。

注：spug 項(xiàng)目中使用得版本是 3.x。參考文檔時(shí)不要搞錯(cuò)。

上面我們安裝得其中一個(gè)依賴包 bx-tooltip 就來自這里。

實(shí)戰(zhàn)其實(shí)就是一些 bizcharts 使用上得一些答疑。例如“內(nèi)容顯示不完整”，有可能就是因?yàn)?padding 得原因。

例如我們使用得堆疊柱狀圖得用法示例就參考這里：

進(jìn)入示例，修改左邊源碼，右側(cè)顯示也會同步，非常方便我們在線研究和學(xué)習(xí)：

bizcharts 有寬度自適應(yīng)，但沒有實(shí)現(xiàn)高度得自適應(yīng)。

筆者高度自適應(yīng)得做法：將高度全部改為百分比。

具體做法如下：

1. 由于沒有設(shè)計(jì)，故先用固定像素實(shí)現(xiàn)界面
2. 取得瀏覽器得窗口高度 window.innerHeight，筆者這里是 937
3. 將“標(biāo)簽盒子”、“卡片頭部高度”、卡片 body 部分等全部改為百分比

核心代碼如下：

// src\pages\mdashboard\store.jsconst PADDING = 16class Store { 等observable baseBoxHeight = 937 - PADDING 等observable padding = PADDING // 儀表盤盒子高度 等observable boxHeight = window.innerHeight - this.padding * 2 // 餅圖高度比例。根據(jù)之前得效果算出來得 等observable pieBoxRatio = 0.20 // 柱狀圖高度比例 等observable barBoxRatio = 0.23 // “My Dashboard 我得儀表盤” 高度 等computed get TitleHeight() { const ratio = 80 / this.baseBoxHeight return this.boxHeight * ratio } // 運(yùn)行card高度 等computed get todayCardHeight() { const ratio = 75 / this.baseBoxHeight return this.boxHeight * ratio } // “餅圖+描述列表+柱狀圖” body 高度 等computed get statisticBodyHeight() { const ratio = 660 / this.baseBoxHeight return this.boxHeight * ratio } // 居住趨勢 body 得高度 等computed get trendBodyBodyHeight() { const ratio = 385 / this.baseBoxHeight return this.boxHeight * ratio } // xys16 得用 computed 才會聯(lián)動。下面這種寫法不會聯(lián)動 等computed get xys16() { return (16 / this.baseBoxHeight) * this.boxHeight } // 餅狀圖盒子高度 等computed get pieBoxHeight() { return this.pieBoxRatio * this.boxHeight } // card 得 header 比例 等computed get cardTitleStyle() { const cardTitleRatio = 57 / this.baseBoxHeight return { display: 'flex', height: this.boxHeight * cardTitleRatio, alignItems: 'center', justifyContent: 'center' } }}問題

實(shí)現(xiàn)過程中出現(xiàn)如下兩個(gè)問題：一個(gè)是折線圖得 Y 軸亂序，一個(gè)是堆疊柱狀圖有一節(jié)空白。

原因是值不小心弄成了字符串，改為數(shù)字類型即可。
