我已經使用openlayers 3在我的地圖中上傳了geojson文件。geojson文件是FeatureCollection,包含5個LineString類型的功能。 如何以不同的顏色區分我的路徑? 如果我將顏色添加到geojson文件的樣式中,則不會讀取該顏色,並且如果向筆觸添加顏色,則所有功能都將以單色着色。功能集合中每個功能的不同顏色
下面我添加代碼。
謝謝。
var vector = new ol.layer.Vector({
source: new ol.source.Vector({
format: new ol.format.GeoJSON(),
url: 'http://localhost/joggo_wp/percorsi.geojson'
}),
style: new ol.style.Style({
stroke: new ol.style.Stroke({
color: "#ff000",
width: 2.5,
})
}),
});
FILE以GeoJSON:
