vue3使用echarts绘制地图-编程知识

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

<template><div ref="myChart" style="width: 1000px; height: 1000px;"></div>

})</script>
<style></style><!-- <template ><div :id="id" :style="{ width: width, height: height }"></div>
</template>
<script setup>
import * as echarts from 'echarts'
import { onMounted, watch} from 'vue'
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));let option = props.option;option && myChart.setOption(option);}</script>
<style></style> -->

实现效果如下图：【上述代码使用的是可视化社区里的这个案例，如有需要自行按需更改即可！】
在这里插入图片描述
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>
<style></style>

直接在父组件中使用

<script setup>
import Echarts from './components/Echarts.vue';
import { ref, onMounted } from 'vue';
