I have created an application with OpenLayers 4.1.0 that imports GeoJSON vector data, allows selecting of polygons, changes "processed" property value of selected polygon from 0 to 1 and prepares edited data for export.
Now, I'm trying to rewrite that application in OL 2.13.1: https://github.com/mleontenko/openlayers2-edit-properties/blob/master/map.html
This is the part i can't figure out how to rewrite in OL2:
//change "processed" property value from 0 to 1 select.getFeatures().item(0).set('processed', 1); //store geojson to variable for export var writer = new ol.format.GeoJSON(); var geojsonStr = writer.writeFeatures(vectorSource.getFeatures());enter code here
What it needs to do is:
-Change selected polygon's "processed" property from 0 to 1
-store GeoJson to variable as string so i can export it later
