vue3使用echarts绘制地图
- 安装echarts
npm install echarts
- 下载地图的json数据【我这里是把json数据单独粘出来然后新建了一个文件china.json】
下载中国及各个省份的地图数据 - 引入
import chinaJson from './china.json'
- 绘制地图

5. 封装echarts【具体封装流程可参考博客】
<template >
<div :id="id" :style="{ width: width, height: height }">
</div>
</template>
<script setup>
import * as echarts from 'echarts'
import { onMounted, watch } from 'vue'
import chinaJson from './china.json'
const props = defineProps({
id: {
type: String,
default: 'myChart'
},
width: {
type: String,
default: '100%'
},
height: {
type: String,
default: '100%'
},
option: {
type: Object,
default: () => { }
}
})
let myChart = null;
watch(props.option, () => {
drawEcharts();
})
onMounted(() => {
drawEcharts();
});
function drawEcharts() {
myChart = echarts.init(document.getElementById(props.id));
echarts.registerMap('china', chinaJson);
let option = props.option;
option && myChart.setOption(option);
}
</script>
