echarts使用百度地图

前情提要

获得百度地图授权的ak密钥
引入echarts的百度地图
准备好echarts百度地图需要的数据
自定义百度地图的样式
去掉百度地图的logo

一、获取百度地图的ak密钥

首先得注册成为百度开发者 https://lbsyun.baidu.com/

成为开发者后，点击控制台

选择创建应用

创建完成之后就可以拿到ak密钥，我们将ak密钥在项目中使用，一般放在html模板，通过js引入

二、引入echarts的百度地图

在项目的全局额外引入

import 'echarts/extension/bmap/bmap';

三、准备数据

<template><div><Echart :options="options" id="mapchina" height="3.9063rem" width="3.9063rem"></Echart></div>
</template><script>
import Echart from '@/common/echart';
// import zhongxian from "../../../common/map/zhongxian";
// import zhongguo from '../../../common/map/zhongguo';
export default {data() {return {options: {},dataValue: [{ name: '海门', value: 9 },{ name: '鄂尔多斯', value: 12 },{ name: '招远', value: 12 },{ name: '舟山', value: 12 },{ name: '齐齐哈尔', value: 14 },{ name:

四、在Echarts组件中自定义百度地图的样式

<template><div :id="id" :class="className" :style="{ height: height, width: width }" />
</template><script>
export default {name: 'echart',props: {className: {type: String,default: 'chart',},id: {type: String,default: 'chart',},width: {type: String,default: '100%',},height: {type: String,default: '2.5rem',},options: {type: Object,default: () => ({}),},},data() {return {chart: null,};},watch: {options: {handler(options) {// 设置true清空echart缓存this.chart.setOption(options, true);},deep: true,},},mounted() {// this.$echarts.registerTheme('tdTheme', tdTheme); // 覆盖默认主题this.initChart();},beforeDestroy() {this.chart.dispose();this.chart = null;},methods: {initChart() {// 初始化echart,我之间将echarts放在vue原型上了，所以可以使用$echartsthis.chart = this.$echarts.init(this.$el);this.chart.setOption(this.options, true);setTimeout(() => {// 修改百度地图的样式const bmap = this.chart.getModel().getComponent('bmap').getBMap();bmap.setMapStyle({styleJson: [{featureType: 'water',elementType: 'all',stylers: {color: '#102d68',},},{featureType: 'land',elementType: 'all',stylers: {color: '#091934',},},{featureType: 'boundary',elementType: 'geometry',stylers: {color: '#064f85',},},{featureType: 'railway',elementType: 'all',stylers: {visibility: 'off',},},{featureType: 'highway',elementType: 'geometry',stylers: {color: '#004981',},},{featureType: 'highway',elementType: 'geometry.fill',stylers: {color: '#005b96',lightness: 1,},},{featureType: 'highway',elementType: 'labels',stylers: {visibility: 'on',},},{featureType: 'arterial',elementType: 'geometry',stylers: {color: '#004981',lightness: -39,},},{featureType: 'arterial',elementType: 'geometry.fill',stylers: {color: '#00508b',},},{featureType: 'poi',elementType: 'all',stylers: {visibility: 'off',},},{featureType: 'green',elementType: 'all',stylers: {color: '#102f6d',visibility: 'off',},},{featureType: 'subway',elementType: 'all',stylers: {visibility: 'off',},},{featureType: 'manmade',elementType: 'all',stylers: {visibility: 'off',},},{featureType: 'local',elementType: 'all',stylers: {visibility: 'off',},},{featureType: 'arterial',elementType: 'labels',stylers: {visibility: 'off',},},{featureType: 'boundary',elementType: 'geometry.fill',stylers: {color: '#029fd4',},},{featureType: 'building',elementType: 'all',stylers: {color: '#1a5787',},},{featureType: 'label',elementType: 'all',stylers: {color: '#0e9cd2','font-weight': 'bold',visibility: 'on',},},{featureType: 'administrative', // 村名elementType: 'labels',stylers: {visibility: 'on',},},{featureType: 'administrative',elementType: 'labels.text.stroke',stylers: {color: '#0e9cd200',weight: 0,},},{featureType: 'road', // 路名elementType: 'labels',stylers: {visibility: 'off',},},],});}, 1000);},},
};
</script>

五、去掉百度的logo

// 去掉百度地图的logo
.anchorBL {display: none !important;
}
