话不多说,先看效果图
效果图
实际效果网页
demo开始
1.你需要一个echart广州地图的JSON文件,这里我给大家准备好了
2.然后你需要一个echart的js包,你可以到echart的官网进行下载
3.贴出我的参考代码(由于时间急,没有细细的整理代码,就直接扔出来了, 如有错误之处,请留言指明)

// 基于准备好的dom，初始化echarts实例
var myChart = echarts.init(document.getElementById('main'));
myChart.showLoading();
//步骤一:创建异步对象
var ajax = new XMLHttpRequest();
//步骤二:设置请求的url参数,参数一是请求的类型,参数二是请求的url,可以带参数,动态的传递参数starName到服务端
ajax.open('get','guangzhou.json');
//步骤三:发送请求
ajax.send();
//步骤四:注册事件 onreadystatechange 状态改变就会调用
ajax.onreadystatechange = function () {
if (ajax.readyState==4 &&ajax.status==200) {
//步骤五 如果能够进到这个判断 说明 数据 完美的回来了,并且请求的页面是存在的
myChart.hideLoading();
geoCoordMap=ajax.response;
//将地图注册上去
echarts.registerMap('guangzhou',ajax.response );
// 使用刚指定的配置项和数据显示图表。
myChart.setOption(option);
