从外部访问Leaflet.js GeoJson功能 [英] Accessing Leaflet.js GeoJson features from outside

问题描述

我想与 L。的境界外的传单动画地图GeoJson叠加层（多边形）进行交互，但我似乎无法访问由 L创建的对象。。

I want to interact with a leaflet powered map's GeoJson overlay (polygons) from outside of L.'s realm, but I don't seem to be able to access objects created by L..

互动将包括：

• getBounds（myFeature）


• fitBounds（myFeature）


• setStyle
  etc

我可以看到Leaflet暴露L.GeoJSON.getFeature（），但我似乎无法挤出任何东西。没有文档，检查员似乎建议不要提出争议...：\

I can see Leaflet exposing L.GeoJSON.getFeature(), but I don't seem to be able to squeeze anything out of it. No documentation, and the inspector seems to suggest it does not take arguments... :\

这是为了将来的发展吗？

Is this just there for future development?

推荐答案

您可以使用getLayer通过其id获取该功能。

http://leafletjs.com/reference.html#layergroup-getlayer

You may use getLayer to get the feature by its id.
http://leafletjs.com/reference.html#layergroup-getlayer

var geojsonLayer = L.geoJson(data,{
    onEachFeature: function(feature, layer) {
        layer._leaflet_id = feature.id;                                    
    }});
geojsonLayer.addTo(map);

feature = geojsonLayer.getLayer(12345); //your feature id here
alert(feature.feature.id);
