[OpenLayers-Users] WG: Display a Attribute of a GML-File on label in OpenLayers

[Gau, Hans-Jürgen]

Hi,

yes, runs with styleMap-Object.

...
		var gmllayer = new OpenLayers.Layer.Vector("GML", {
                protocol: new OpenLayers.Protocol.HTTP({
                    url: "./gml/test.gml",
                    format: new OpenLayers.Format.GML({extractAttributes: true})   
					}),
					styleMap: new OpenLayers.StyleMap({strokeColor:"#2C5C91", fillColor:"#2C5C91",strokeWidth:1,fillOpacity: 0.1, 
					label:"${name}",labelOutlineColor:"white",labelOutlineWidth:1 }),
					strategies: [new OpenLayers.Strategy.Fixed()]
            });
...

Thanks!

Hi,

Create a styleMap object as well:
var gmllayer = new OpenLayers.Layer.Vector("GML", { 
  ...
  styleMap: new OpenLayers.StyleMap({strokeColor:"#2C5C91",
    fillColor:"#2C5C91",strokeWidth:1,fillOpacity: 0.1, 
    label:"${name}",labelOutlineColor:"white",labelOutlineWidth:1 }),
  ...
});

Regards,

Xavier Mamano
