[OpenLayers-Users] changing color of a feature

[Piero Campa]

Hi Sunny, 
if you want to do this I think it's better if you create a feature layer via
WFS, because a WMS layer is a raster.

Try with something like:

		myFeaturesLayer = new OpenLayers.Layer.Vector("name", {
			styleMap: myStyle,
			strategies: [wfsStrategy],
			protocol: new OpenLayers.Protocol.WFS({
				url: wfsurl,
				featureType: "layerName", // on the server
				featureNS: "workspaceNamespaceURI", // on the server
				srsName: "EPSG:xxxx",
				version: "1.1.0" // : supports reprojection
				})
		});

then you can define myStyle in order to have a different style (color for
example) when you select (click) on a feature.

		var myStyle = new OpenLayers.StyleMap({
			"default": new OpenLayers.Style({
                                <parameters>
			}), 
			"select": new OpenLayers.Style({
                                <parameters>
			})
		});

Good work!
