如何從OpenLayers中的GML矢量圖層升級到VECTOR

Question

根據OpenLayers的說法，Openlayers.Layer.GML已經過折舊，並且在Ver。 2.12。我需要移動到矢量圖層，但我無法弄清楚。

在我以前的版本我已經把它定義爲：

  //Locations and UnitLocations layer - GeoJSON 
      var LocationStyle = new OpenLayers.Style({ 
       strokeColor: "#5B5B5B", 
       strokeWidth: 1, 
       fillColor: "#F4FBA1", 
       pointRadius: 10, 
       strokeOpacity: 0.8, 
       fillOpacity: 0.8, 
       label: "${Location}", 
       labelYOffset: "-20", 
       labelAlign: "cc", 
       fontColor: "#000000", 
       fontOpacity: 1, 
       fontFamily: "Arial", 
       fontSize: 12, 
       fontWeight: "300" 
      }); 


      var LocationURL = "http://bit.ly/Nfe6IH?q=ICS_Locations&IncidentCode=" + "VAJA%20PSI%2012" + "&key=" + Math.random(); 
      Locations = new OpenLayers.Layer.GML("Locations", LocationURL, { 
       format: OpenLayers.Format.GeoJSON, 
       projection: new OpenLayers.Projection("EPSG:4326"), //4326 for WGS84 
       styleMap: new OpenLayers.StyleMap(LocationStyle) 
      }); 

在版本。 Openlayers的2.12版本不再支持。你有什麼樣的例子，我怎麼能做到這一點？

謝謝。

Answer 1

嘗試以下調整代碼：

Locations = new OpenLayers.Layer.Vector("Locations", { 
       strategies: [new OpenLayers.Strategy.Fixed()], 
       protocol: new OpenLayers.Protocol.HTTP({ 
        url: LocationURL, 
        format: new OpenLayers.Format.GeoJSON() 

       }), 
       displayInLayerSwitcher: false, 

      }); 

Answer 2

// format use: new OpenLayers.Format.GPX 

       var orange = new OpenLayers.Layer.Vector("gpx", { 
        protocol: new OpenLayers.Protocol.HTTP({ 
         url: "mGPX_123123123.gpx", 
         format: new OpenLayers.Format.GPX 
        }), 
        strategies: [new OpenLayers.Strategy.Fixed()], 
        visibility: true,           
        projection: new OpenLayers.Projection("EPSG:4326") 
       }); 
       myMap.addLayer(orange);
