I tried with this code:
var lgpx = new OpenLayers.Layer.Vector("Track", {
style: {strokeColor: 'red', strokeWidth: 10,
strokeOpacity: 0.5},
projection: map.displayProjection,
strategies: [new OpenLayers.Strategy.Fixed()],
protocol: new OpenLayers.Protocol.HTTP({
url: 'gpx.php?imei='+imei+'&from='+from+'&to='+to,
format: new OpenLayers.Format.GPX({
extractAttributes: true,
extractStyles: false,
maxDepth: 4,
extractTracks: true,
extractRoutes: false,
extractWaypoints: false
})
})
});
map.addLayer(lgpx);
lgpx.events.register('loadend',lgpx,function() {
var bounds = this.getDataExtent();
map.zoomToExtent(bounds);
});
var hoverSelect = new OpenLayers.Control.SelectFeature(lgpx, {
hover: true,
multiple: true,
geometryTypes: ["OpenLayers.Geometry.LineString"],
renderIntent: "temporary",
onSelect: function(f) {
var content = 'popup';
popup = new OpenLayers.Popup.FramedCloud("Info",
f.geometry.getBounds().getCenterLonLat(),
null,
content,
null, true, function() {
hoverSelect.unselectAll();
}
);
f.popup = popup;
map.addPopup(popup);
},
onUnselect: function(f) {
if (f.popup) {
map.removePopup(f.popup);
f.popup.destroy();
delete f.popup;
}
}
});
map.addControl(hoverSelect);
hoverSelect.activate();
and the GPX file is like this:
<gpx xmlns="http://www.topografix.com/GPX/1/1";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; version="1.1"
creator="Waze Mobile Ltd (1.4.0.1) -

xsi:schemaLocation="http://www.topografix.com/GPX/1/1
http://www.topografix.com/GPX/1/1/gpx.xsd";>
<trk xmlns="">
<trkseg>
<trkpt lat="37.0617024" lon="14.9067984">
<time>2010-05-16T10:46:10Z</time>

</trkpt>
.............
I would like to display inside the popup time and name attributes

Hi,
I'm trying to display a popup on mouse over GPX track. This is the
code used to load the track:
onSelect: function(feature) {
--------------> Here I want to display a popup with info from the GPX file
},
onUnselect: function(feature) {
I use eventListeners instead of onSelect onUnselect.
bye
maxx
Code for the popup:
var highlightCtrl = new OpenLayers.Control.SelectFeature([vlayer,
clayer], {
hover: true,
highlightOnly: true,
multiple: true,
geometryTypes: ["OpenLayers.Geometry.LineString"],
renderIntent: "temporary",
eventListeners:
{
featurehighlighted: function(f)
{
popup = new OpenLayers.Popup("mylayer",
f.feature.geometry.getBounds().getCenterLonLat(),
null,
'some html text',
null,
true);
popup.autoSize=true;
// popup.panMapIfOutOfView=true;
f.feature.popup = popup;
map.addPopup(popup);
},
featureunhighlighted: function(f)
{
map.removePopup(f.feature.popup);
f.feature.popup.destroy();
f.feature.popup = null;
}
}
});
map.addControl(highlightCtrl);
highlightCtrl.activate();
(popup is a global variable)
Code to open a gpx file:
var tmplayerGps= new OpenLayers.Layer.GML('myfile', path,
{
format: OpenLayers.Format.GPX,
formatOptions: {
extractAttributes: true,
extractStyles: false,
maxDepth: 2,
extractTracks: true,
extractRoutes: false,
extractWaypoints: false
},
'styleMap': styleMap,
projection: map.displayProjection
});
