如何获得给定功能的图层?当用户在地图上选择要素时,我需要访问某些图层属性。在ol2中我使用了feature.layer。

目前,无法从功能转到图层,但您可以创建一个解决方法,如:
ol.Feature.prototype.getLayer = function() {
var this_ = this, layer_;
var sameFeature = function(feature){
return (this_ === feature) ? true : false;
};
map.getLayers().forEach(function(layer){
var source = layer.getSource();
if(source instanceof ol.source.Vector){
var features = source.getFeatures();
if(features.length > 0){
var found = features.some(sameFeature);
if(found){
layer_ = layer;
}
}
}
});
return layer_;
};
然后使用:
var layer = feature.getLayer();
