实现
1、将上面代码克隆下来，本地新建html以及需要的js文件等
需要一个leaflet-echarts.js的核心js文件，需要一个echart的源码js文件，还需要一个迁徙数据的mihration.json数据文件。
js文件都可以在代码仓库中找到，json文件可以在在线演示地址中访问接口地址，并且另存为获取。
2、html中再加上leaflet本身需要的css和js文件
<link rel="stylesheet" href="https://unpkg.com/leaflet@1.7.1/dist/leaflet.css" />
<script type="text/javascript" src="https://unpkg.com/leaflet@1.7.1/dist/leaflet.js"></script>
<script src="./js/leaflet-echarts.js"></script>
<script src="./js/echarts.source.js"></script>
<script src="http://cdn.bootcss.com/jquery/1.11.0/jquery.min.js"></script>
为了方便使用ajax模拟请求json数据，这里还引入了jquery。
3、需要使用ajax模拟请求后台获取json数据。
$.ajax({
url: 'http://localhost:3000/json/migration.json',
type: "get",
dataType: 'json',
success: function (data) {
for (var key in data) {
data[key].forEach(function (value, index) {
data[key][index].num = Number(value.num);
})
}
option.series[0].markLine.data = data.allLine.sort(function (a, b) {
return b.num - a.num
}).slice(0, 3000).map(function (line) {
return [{
geoCoord: getGeoCoord(line.start)
}, {
geoCoord: getGeoCoord(line.end)
}]
});
option.series[0].markPoint.data = data.topCityOut.map(function (point) {
return {
geoCoord: getGeoCoord(point.name)
}
});
overlay.setOption(option);
}
});这里可以使用很多种方式，可以使用js请求本地json(注意跨域问题)，或者使用java编写后台接口返回数据。
这里使用nginx映射的方式去模拟返回json数据。
Nginx映射本地json文件，配置解决浏览器跨域问题，提供前端get请求模拟数据：
