Hi,
After looking at
http://gis.ibbeck.de/ginfo/apps/OLExamples/OL26/examples/styles_unique_with_group_wfs.htmlI
managed to find a
work around . I have two wfs point layers, and can activate the
selectFeature for the currently selected layer via a radio button.
Some of my features were superimposed on top of other layers. However when
the needed layer is selected via the radio buttons the selected layer is
superimposed.
Heres my code
//inside init()
var myHTML = "<input type=radio name=myRadio
onclick=test(2)><label>Cities</label> <img src='./img/marker-blue.png'>
<br>" myHTML += "<input type=radio name=myRadio
onclick=test(3)><label>Stations</label> <img src='./img/marker-gold.png'>"
document.getElementById("controls").innerHTML = myHTML;
//
//outside init()
var myLayer; //global variable
var myObj; //global variable
function test(id) {
myLayer =id;
if(selectControl)
{
//alert("Hiiiiiiiiiiiii");
selectControl.destroy();
}
selectControl = new
OpenLayers.Control.SelectFeature(map.layers[id],
{
onSelect : onFeatureSelect,
onUnselect: onFeatureUnselect
});
map.addControl(selectControl);
selectControl.activate();
//I didnt think this it necessary to unregister because the
control is destroyed above
//map.layers[id].events.unregister('featureselected',
map.layers[id], regFeatureSelected);
//map.layers[id].events.unregister('featureunselected',
map.layers[id], regFeatureUnselected);
}
function onFeatureSelect()
{
var currentLayer = map.layers[myLayer];
var obj = currentLayer.selectedFeatures[0];
myObj = obj
//alert(obj.attributes['name']);
popup = new OpenLayers.Popup.FramedCloud("chicken",
obj.geometry.getBounds().getCenterLonLat(),
null,
"<div style='font-size:.8em'>" +
obj.attributes['name'] +"<br />" + "</div>",
null, true, onPopupClose);
obj.popup = popup;
map.addPopup(popup);
}
function onPopupClose(evt) {
selectControl.unselect(myObj);
}
function onFeatureUnselect()
{
//alert("from regFeatureUnselected");
map.removePopup(myObj.popup);
myObj.popup.destroy();
myObj.popup = null;
}
Hope this was helpful.
