echarts显示全国地图(附带全国地图json数据)
实现echarts全国地图展示,可点击进入省份,可根据经纬度坐标进行位置标记
·
前言
实现echarts全国地图展示,可点击进入省份,可根据经纬度坐标进行位置标记
一、效果展示
全国地图
省级地图(西藏)
二、实现步骤
1.安装echarts
// 下载echarts
npm install echarts --save
2.在main.js中全局注册echarts
import * as echarts from 'echarts';
Vue.prototype.$echarts = echarts;
//直接this.$echarts使用
3.导入地图json数据
https://download.csdn.net/download/weixin_44088179/88251920?spm=1001.2014.3001.5501
下载后放入自己项目中(我放在static目录中),这里是全国及各个省份的所有json数据集合,如还需市、区级还需自行下载,地址如下:
http://datav.aliyun.com/portal/school/atlas/area_selector 可下载全国所有地区的json数据(全国、省、市、区)
4.创建cityExport.js文件
创建cityExport.js文件,汇总所有地图json (引入路径记得修改)
let cityList = [
{
name: '北京市',
code: 110000,
data: require('../../../static/json/beijing.json'),
},

let china = require('../../../static/json/china.json')
export default {
cityList: cityList,
china: china
};
4.创建地图
代码如下(示例):
<template>
<div class="map" style="height: 410px;position: relative;">
<img @click="rebackMap"
v-show="isreturn"
src="@/static/img/return.png"
alt=""
style="z-index:999;
position: absolute;
right: 20px;
top: 15px;">
<div id="map" style="height: 410px;"></div>
</div>
</template>
<script>
import cityExport from './cityExport.js';
import * as echarts from 'echarts';
export default {
data() {
return {
isreturn: false, // 是否显示返回全国地图按钮
mapChart: null, //地图对象
mapOption: null,//地图属性
dataList: [ //地图标记经纬度坐标和code码,可只要经纬度
{ name: "西藏", value: [91.23, 29.5, 2333] },
{ name: "黑龙江", value: [128.03, 47.01, 1007] },
],
}
},
mounted() {
this.getMap()
},
methods: {
getMap() { //地图
if (!this.mapChart) {
this.mapChart = this.$echarts.init(document.getElementById('map'));
}
this.mapOption = {

},
],

},
shadowColor: "#457b9d",
shadowOffsetX: -2,
shadowOffsetY: 2,

}
],
};
// 地图注册,第一个参数的名字必须和option.geo.map一致
this.$echarts.registerMap('china', cityExport.china);
this.mapChart.setOption(this.mapOption);
//地图点位点击事件
this.mapChart.on('click', params => {
// 获取点击的省份名称
let provinceName = params.name
// 判断点击的省份是否有标记点 有则只显示该省的标记 否则会将其他省份的坐标点一起显示
this.dataList.map(item => {

this.mapOption.series[0].data = [item];
}
})
// 进入省级地图
cityExport.cityList.map(value => {

this.mapChart.clear();
this.mapOption.geo.map = 'Pmap';
this.$echarts.registerMap('Pmap', value.data)

this.isreturn = true;
}
});
})
},
rebackMap() { //返回全国地图
this.mapChart.clear();
this.mapOption.series[0].data = this.dataList //重新标记
