前端jq/vue echarts中国地图的实现
一、jquery项目实现echarts中国地图
1、引入相关资源文件 jquery、echarts 等
<script src="https://cdn.bootcdn.net/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script src="https://cdn.bootcdn.net/ajax/libs/echarts/4.8.0/echarts.min.js"></script>
2、下载中国地图json数据中国地图json数据下载地址
3、展示代码
<!DOCTYPE html>
<html>
<head>
<title>中国地图</title>
<meta charset="utf-8">
</head>
<body>
<div id="main" style="width: 100%;height:800px;"></div>
</body>
<script src="https://cdn.bootcdn.net/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script src="https://cdn.bootcdn.net/ajax/libs/echarts/4.8.0/echarts.min.js"></script>
<script type="text/javascript">
//获取地图数据
$.get('china.json', function (chinaJson) {
//注册地图
echarts.registerMap('china', chinaJson);
// 基于准备好的dom，初始化echarts实例
var myChart = echarts.init(document.getElementById('main'));

二、vue项目实现echarts中国地图
1、后期加上
