Hi All,
I'm getting some strange behavior with the select and highlight feature
select controls. This maybe sloppy, but yesterday this "worked" fine, (i.e.
the sites highlighted when moused-over and popups appeared). Today, the
sites highlight to a light blue, and sometimes stay highlighted, and no
popups appear. Not sure what's going on.
here's my code. I'm using the url to the api rather than a local file.
var map, controls, selectControl, selectedFeature;
function init() {
map = new OpenLayers.Map ("map",
{
controls:[
new OpenLayers.Control.Navigation(),
new OpenLayers.Control.PanZoomBar(),
new OpenLayers.Control.LayerSwitcher(),
new OpenLayers.Control.Attribution()],
sphericalMercator: true,
maxExtent: new
OpenLayers.Bounds(-20037508.34,-20037508.34,20037508.34,20037508.34),
maxResolution: 156543.0399,
numZoomLevels: 19,
units: 'm',
projection: new OpenLayers.Projection("EPSG:900913"),
displayProjection: new OpenLayers.Projection("EPSG:4326"),
}
);
var myBaseLayer = new OpenLayers.Layer.WMS( "OpenLayers WMS",
"http://labs.metacarta.com/wms/vmap0";, {layers: 'basic', projection:
"myproj"} );
map.addLayer(myBaseLayer);
var topo = new OpenLayers.Layer.GML("Topography", "data/test4.gml",
{
projection: new OpenLayers.Projection("EPSG:4326")});
map.addLayer(topo);
// Selection and hoverstate controls
var report = function(e) {
OpenLayers.Console.log(e.type, e.feature.id);
};
var highlightCtrl = new OpenLayers.Control.SelectFeature(topo, {
hover: true,
highlightOnly: true,
renderIntent: "temporary",
eventListeners: {
beforefeaturehighlighted: report,
featurehighlighted: report,
featureunhighlighted: report
}
});
var selectCtrl = new OpenLayers.Control.SelectFeature(topo,
{clickout: true}
);
map.addControl(highlightCtrl);
map.addControl(selectCtrl);
highlightCtrl.activate();
selectCtrl.activate();
//Popups and
function onPopupClose(evt) {
selectControl.unselect(selectedFeature);
}
function onFeatureSelect(feature) {
selectedFeature = feature;
popup = new OpenLayers.Popup.FramedCloud("chicken",
feature.geometry.getBounds().getCenterLonLat(),
null,
"<div style='font-size:.8em'>Feature: "
+ feature.attributes.title +"<br />Area: " +
feature.attributes.newsite_+"<br/>This should do something<br/> This should
do something else</div>",
null, true, onPopupClose);
feature.popup = popup;
map.addPopup(popup);
}
function onFeatureUnselect(feature) {
map.removePopup(feature.popup);
feature.popup.destroy();
feature.popup = null;
}
if( ! map.getCenter() ){
topo.events.register('loadend', topo,
function(){map.zoomToExtent(topo.getDataExtent())});
map.setCenter(null, null);
};
}
