perform your own ajax call, requesting the 2 layers and getting the single return dictionary/object in something like geojson, then add them to the target layer manually ?
or some knick-nack where there is a 'master layer' that is connected to a url, and another that receives features from it based on an attribute value. -i -----Message d'origine----- De : openlayers-dev-boun...@lists.osgeo.org [mailto:openlayers-dev-boun...@lists.osgeo.org] De la part de khanh703 Envoyé : Wednesday, 4 June 2014 16:50 À : openlayers-dev@lists.osgeo.org Objet : [OpenLayers-Dev] Plot features onto multiple layers from one HTTP request I would like to plot features onto multiple layers from one HTTP request ie (Burgers, Hot Dogs, etc...) I can achieve what I want by making multiple request but would rather make one request. How can I achieve plotting on different layers: 1. Change the protocol attributes to read from local ARRAY and do a while loop or 2. Change my FeatureCollection structure This below works but all features are plotted on the same layer: markers = new OpenLayers.Layer.Vector(thisLayer, { preFeatureInsert: preFeatureInsert, strategies: [ new OpenLayers.Strategy.Fixed(), new OpenLayers.Strategy.Cluster({ distance: 20 }) ], protocol: new OpenLayers.Protocol.HTTP({ url: protocolUrl, format: protocolFormat }), projection: MapProj, formatOptions: { extractStyles: true, extractAttributes: true }, styleMap: new OpenLayers.StyleMap({ "default": style, "select": style }), catID: 0 }); with this collection: { "type": "FeatureCollection", "features": [{ "type": "feature", "properties": { "id": "7943", "name": "Bobs Burger", "category": "57", "color": "9875c3", "timestamp": "1400149988" }, "geometry": { "type": "Point", "coordinates": [-76.437099, 39.041711] } }, { "type": "feature", "properties": { "id": "7944", "name": "Hot Diggity", "category": "54", "color": "b33838", "timestamp": "1400150184" }, "geometry": { "type": "Point", "coordinates": [-76.436586, 39.041696] } }] } -- View this message in context: http://osgeo-org.1560.x6.nabble.com/Plot-features-onto-multiple-layers-from-one-HTTP-request-tp5144030.html Sent from the OpenLayers Dev mailing list archive at Nabble.com. _______________________________________________ Dev mailing list d...@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/openlayers-dev _______________________________________________ Dev mailing list d...@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/openlayers-dev
