步骤
- 引入echarts.js,jquery，并创建图表容器、初始化echarts对象
<script src="./lib/echarts.min.js"></script>
<script src="./lib/jquery.min.js"></script>
<style>
.demo {
400px;
height: 300px;
background-color: pink;
}
</style>
<div class="demo"></div>
<script>
const myChart = echarts.init(document.querySelector(".demo"));
</script>
- 使用jquery发送ajax请求获取地图的json文件数据
矢量地图数据参考地址：http://datav.aliyun.com/portal/school/atlas/area_selector
代码：
$.getJSON(
"https://geo.datav.aliyun.com/areas_v3/bound/220000_full.json",
(res) => {
console.log(res);
}
);
- 往echarts全局对象上注册地图矢量的数据，并在实例化的echarts对象中设置geo
$.getJSON(
"https://geo.datav.aliyun.com/areas_v3/bound/220000_full.json",
(res) => {
echarts.registerMap("chinaMap", res);
myChart.setOption({
geo: {
type: "map",
map: "chinaMap", // 注意：此处使用的字符串必须和上面"echarts.registerMap"注册时传递的第一个参数名保持一致
},
});
}
);
