实现功能
1、系统登录后的可视化面板页面
原本不想写这篇文章，因为它和我们的系统权限、框架没有实质性的关系，但耐不住群友的软磨硬泡，便答应了下来。
我起初的设想，这块功能直接上传到码云上，群友可以根据自己搭建的系统，酌情修改。
安装echarts
npm install echarts --save
搭建面板页面
在panel文件夹，打开index页面，编写布局代码
<template> <div style="display: flex; height: 1080px"> <div style="width: 80%"> <div style="height: 25%; display: flex; margin-bottom: 5px" class="boxStyle" > <div style="width: 50%" class="boxStyle"> </div> <div style="width: 50%; margin-left: 5px;" class="boxStyle" > 2 </div> </div> <div style="height: 45% ;margin-bottom: 5px" class="boxStyle"> 3 </div> <div style="height: 28%" class="boxStyle"> 4 </div> </div> <div style="width: 20%; margin-left: 5px; display: flow-root" class="panelContent boxStyle" > <div style="width: 100%; height: 50%; margin-bottom: 5px" class="boxStyle" > 特色功能 </div> <div style="width: 100%; height: 50%" class="boxStyle">关于作者</div> </div> </div> </template> <script lang="ts" > import * as echarts from "echarts"; import { defineComponent } from "vue"; export default defineComponent({ props: { // openPageData: { // type: Object as PropType<buttonModel>, // required: true, // }, }, setup(props, context) { return {}; }, components: {}, }); </script> <style scoped> .panelContent { font-size: 12px; justify-content: right; align-items: center; } .boxStyle { border: 1px solid #00152914; box-shadow: 0 1px 4px #00152914; } </style>
布局样式如下
填充盒子1的内容
在api文件夹下，创建一个文件夹panel，然后再该文件夹下创建一个echarts.ts的文件，编写如下代码
export const echartsOne = { title: { text: "系统六芒星图", }, color: ['#67F9D8'], //backgroundColor: "#013954", //背景样式 radar: { // 雷达图的指示器，表示多个变量的标签 indicator: [ { name: "好用", max: 5 }, { name: "易懂", max: 5 }, { name: "简单", max: 5 }, { name: "通用", max: 5 }, { name: "灵活", max: 5 }, { name: "学习", max: 5 }, ], splitArea: { areaStyle: { color: ['#adbecf','#77EADF', '#26C3BE', '#64AFE9', '#428BD4','#2177cd'], shadowColor: 'rgba(0, 0, 0, 0.2)', shadowBlur: 10 } }, axisName: { formatter: '【{value}】', color: '#428BD4' }, }, series: [ { type: "radar", // 雷达图的数据 data: [ { value: [5, 5, 5, 5, 5, 5], }, ], }, ], };
该代码是echarts的雷达图代码。
回到页面，我们把盒子1里的内容替换成
<div id="echarts-one" style="width: 100%; height: 100%"></div>
然后再setup下添加如下代码
onMounted(() => { GetEchartsOneData(); }); function GetEchartsOneData() { var myChart = echarts.init(document.getElementById("echarts-one")); myChart.setOption(echartsOne); }
注意这里的onMounted钩子函数需要添加引用，echartsOne也需要导入。点击vue的提示即可。
完成以上代码，我们预览看下效果
照葫芦画瓢，我们开始编写盒子2、3、4的内容
在echarts.ts中添加
//南丁格尔玫瑰图 export const echartsTWO = { title: { text: "模块访问占比", }, toolbox: { show: true, }, legend: { bottom: "10", }, // backgroundColor: "#013954", //背景样式 series: [ { name: "Nightingale Chart", type: "pie", radius: [25, 80], center: ["50%", "50%"], roseType: "area", // itemStyle: { // borderRadius: 8, // }, data: [ { value: 40, name: "菜单权限" }, { value: 38, name: "角色权限" }, { value: 32, name: "列权限" }, { value: 30, name: "行权限" }, { value: 28, name: "按钮权限" }, { value: 18, name: "接口权限" }, { value: 26, name: "流程" }, { value: 22, name: "表单" }, ], }, ], };

在页面添加
把盒子2所在的地方替换成<div id="echarts-tow" style="width: 100%; height: 100%"></div>
把盒子3所在的地方替换成<div id="echarts-three" style="width: 100%; height: 100%"></div>
把盒子4所在的地方替换成<div id="echarts-four" style="width: 100%; height: 100%"></div>
onMounted(() => { GetEchartsOneData(); GetEchartsTwoData(); GetEchartsThreeData(); GetEchartsFourData(); }); //六芒星图 function GetEchartsOneData() { var myChart = echarts.init(document.getElementById("echarts-one")); myChart.setOption(echartsOne); } //南丁格尔玫瑰图 function GetEchartsTwoData() { var myChart = echarts.init(document.getElementById("echarts-tow")); myChart.setOption(echartsTWO); } //中国地图 function GetEchartsThreeData() { var myChart = echarts.init(document.getElementById("echarts-three")); echarts.registerMap("china", chinaJson as any); //注册可用的地图 myChart.setOption(echartsThree); } //堆叠图 function GetEchartsFourData() { var myChart = echarts.init(document.getElementById("echarts-four")); myChart.setOption(echartsFour); }
特别注意
1、在添加中国地图时，需要下载一个中国地图的json包，放在项目中（我是放在和echarts.ts同级目录下）。下载地址：https://datav.aliyun.com/portal/school/atlas/area_selector
2、在tsconfig.json文件中需要添加"resolveJsonModule": true,的配置，该配置可以让系统允许导入json。

兼容性调整
对应echarts来说，每个图表，它是固定的，就算设置的是百分比，也不随着窗体的大小而自适应屏幕，如下图
要解决以上问题，我们只需要添加一个方法即可
//图标兼容性调整 function resizeEchart(myChart:any) { //监听窗口大小变化(适用于一个页面多个图形) window.addEventListener('resize',()=>{myChart.resize();}) }
然后再myChart.setOption()方法后面添加resizeEchart(myChart);即可解决兼容性问题，如图
//堆叠图 function GetEchartsFourData() { var myChart = echarts.init(document.getElementById("echarts-four")); myChart.setOption(echartsFour); resizeEchart(myChart); }
结语
我们的OverallAuth2.0项目也正式迈入功能开发阶段，可能文章内容逐渐开始复杂化，如果你感兴趣的话，也有跟着博主从0到1搭建权限管理系统的兴趣。
