Question

我正在使用多边形形状文件，我想打开和关闭地图上某些功能的可见性。但是，我无法达到功能的属性。我尝试了下面的代码，但它没有通过循环。我该怎么办？

var map = L.mapbox.map('map', 'mapbox.streets', {attributionControl: true});
var featureLayer =     L.mapbox.featureLayer('melbourneuni.hetjfw29').addTo(map);
featureLayer.on('ready', function(){
// navigate the GeoJSON to get to the coordinates
var geojson = this.getGeoJSON();});
</script>
</body>
</html>

Answer 1

只需使用var geojson = this.getGeoJSON()，例如

featureLayer.on('ready', function(e){
    var geojson = this.getGeoJSON()
    // which returns featureCollection, iterate through `geojson.features` array next as you need
});

使用Mapbox从地图获取要素
