hi,
By using code below, i successfully Draw frature layer over Google Map
var gmap = new OpenLayers.Layer.Google(
"Google Streets", // the default
{'sphericalMercator':true, numZoomLevels: 20 });
wfs = new OpenLayers.Layer.Vector("States", {
strategies: [new OpenLayers.Strategy.BBOX()],
protocol: new OpenLayers.Protocol.WFS({
url: "http://localhost:8080/geoserver/wfs";,
featureType: "traget_grave3",
featureNS: "http://www.openplans.org/TestSpace";,
srsName: "EPSG:900913",
version: "1.1.0",
extractAttributes: true,
isBaseLayer: false,
visibility: true
}),
map.addLayers([gmap,wfs]);
But when I use Filter to draw specific features on Google Map (code
below), then nothing happened and no features draw on Google Map.
Please explain where is problem and how i can fix it. I have already
done great search, but unfortunatelly could not found any solution.
please help!
var myfilter = new OpenLayers.Filter.Comparison({
type: OpenLayers.Filter.Comparison.EQUAL_TO,
property: "GRAV_ID",
value: "3 A 1"
});
wfs = new OpenLayers.Layer.Vector("States", {
strategies: [new OpenLayers.Strategy.BBOX()],
protocol: new OpenLayers.Protocol.WFS({
url: "http://localhost:8080/geoserver/wfs";,
featureType: "traget_grave3",
featureNS: "http://www.openplans.org/TestSpace";,
srsName: "EPSG:900913",
version: "1.1.0",
extractAttributes: true,
isBaseLayer: false,
visibility: true
}),
filter: myfilter
});
map.addLayers([gmap,wfs]);
