OpenLayer 3中的POI [英] POI in OpenLayer 3

问题描述

如果加载点从KML文件指向矢量层

If load points from KML file to vetor layer

var layerPOI = new ol.layer.Vector({
  source: new ol.source.KML({
    projection: projection,
    url: 'data/KML/mydata.kml'
  })
})

如何完整列出所有已加载点(POI)和已加载属性(来自data/KML/mydata.kml)?我认为，例如，进入表格-在地图视图(显示层)中我已经可以了

How can I do a complete listing of all loaded points (POIs) and loaded properties (from data/KML/mydata.kml)? I think, for example, into the table - in map view (display layer) I can is already

非常感谢您的回答

推荐答案

(部分)解决方案:

allPOIs = layerPOI.getSource().getFeatures();
// or if define a source separatly
// allPOIs = sourcePOI.getFeatures(); 
onePOI = allPOIs[0]; // first element in Array
propertiesOfOnePOI = onePOI.getKeys();

propertiesOfOnePOI.forEach(function (elementName, elementIndex){
    console.log( "element index: " + elementIndex + " | element name: " + elementName + " | element value: " + onePOI.get(elementName) );
}); 

但是元素GEOMTERY返回Object. 我尝试获取有关点的其他信息，但我不能- 还有来自KML文件的更多标签-例如，点样式-如何确定显示的图标?

But the element GEOMTERY returns Object. I try to getting additional information about point yet but I can not - Also more tags from KML file - For example, point style - how to determine the displayed icon?

请仍然帮助;)
