大屏-echarts地图的注册使用
我安装的版本是echarts@4.9.0 内含中国、各省核心js和JSON文件 可直接引用,但没有各市区地图文件,若更新到echarts5以上各省市地图文件也不自带了,需到三方库中自行下载,连接如下:js文件获取https://github.com/echarts-mapsJSON文件获取DataV.GeoAtlas地理小工具系列script标签中 echarts注册:import echarts

我安装的版本是echarts@4.9.0 内含中国、各省核心js和JSON文件 可直接引用,但没有各市区地图文件,若更新到echarts5以上各省市地图文件也不自带了,需到三方库中自行下载,连接如下:
js文件获取 https://github.com/echarts-maps
JSON文件获取 DataV.GeoAtlas地理小工具系列
script标签中 echarts注册:
import echarts from 'echarts';
import 'echarts/map/js/china.js' // 核心文件
import './components/city/cityfiles/yancheng.js' // 核心文件
import './components/city/cityfiles/changzhou.js' // 核心文件
import './components/city/cityfiles/wuxi.js' // 核心文件
import yancheng from './components/city/cityfiles/yancheng.json' // 引入json文件
import changzhou from './components/city/cityfiles/changzhou.json' // 引入json文件
import wuxi from './components/city/cityfiles/wuxi.json' // 引入json文件
echarts.registerMap('yancheng', yancheng) // 在echarts中注册使用这个文件
echarts.registerMap('changzhou', changzhou) // 在echarts中注册使用这个文件
echarts.registerMap('wuxi', wuxi) // 在echarts中注册使用这个文件
给个宽高:

window.addEventListener('resize', function() {

给每个区域添加提示框中间的连接线的的时候,是push了两个对象,直接数组生成折线的方法对本项目不适用;另外需要注意的一点是整个echarts图表中文字的自适应,我在项目中自定义的fontsize方法在需要自适应的地方使用:
fontSize(res) { // 如在1920屏宽下字体设置为12px,就可以传入0.12给fontSize fontSize(0.12)
let docEl = document.documentElement,
clientWidth = window.innerWidth || document.documentElement.clientWidth || document.body.clientWidth;
if (!clientWidth) return;
let fontSize = 100 * (clientWidth / 1920);
return res * fontSize;
},
监听窗口变化:
window.addEventListener('resize', function() {
_this.autoWidth();
_this.autoHeight()
});
//解决window.resize 不生效的问题
效果如下:
先这样吧
