make esri.dijit.Popup only return popup when feature is clicked

CraigMcDade — Thu, 20 Sep 2012 11:29:57 GMT

I have a popup/infowindow that returns info for 2 of the layers in my map. However, when I click anywhere in the map the popup also comes up that says "no information available". Is there a way to disable this so that the popup only appears when a feature is clicked?

How are you showing the popup?

I'm guessing it's designed to inform the user that there's nothing of interest at the location that they clicked.

How are you calling the popup - what is causing the query to run? Are you running an IdentifyTask, for example?

You could associate an infoWindow with a feature layer. In that case, the infoWindow will show when clicking on the feature. When you click away from a feature, nothing happens.

Another option is to run a queryTask on click. If there are features found, display them in the infoWindow. If not, don't display the infoWindow.

I would second Steve's suggestion about tying the popup to a feature layer. For example, in one of my maps, I define the popup content at the beginning of my initMap() function like this:

 var removalTemplate = new esri.InfoTemplate();
 removalTemplate.setContent('<table cellspacing=\"5\" style=\"font-size:90%\"><tr><td style=\"vertical-align:top\"><b>Road Name:</b></td><td style=\"vertical-align:top\">${Name}</td></tr><tr><td style=\"vertical-align:top\"><b>Snow Removal Priority:</b></td><td style=\"vertical-align:top\">${Priority:formatPriorityLabel}</td></tr></table>');
 removalTemplate.setTitle('${Name}');

Next, you specify the template when you create the feature layer:

 // Define the Snow Removal Route layer
 theSnowRemovalLayer = new esri.layers.FeatureLayer("URL to feature layer", {
  mode: esri.layers.FeatureLayer.MODE_ONDEMAND,
  infoTemplate:removalTemplate,
  outFields: ["*"],
  opacity:0.80,
  visible: false
 });

Towards the end, but still within the initMap() function, I associate the popup with the specific feature layer:

 dojo.connect(theSnowRemovalLayer,"onClick",function(evt){
  //Listener event for feature selection and the popup info widow
  var query = new esri.tasks.Query();
  query.geometry = pointToExtent(map,evt.mapPoint,15);

  var deferred = theSnowRemovalLayer.selectFeatures(query,esri.layers.FeatureLayer.SELECTION_NEW);
  map.infoWindow.resize(map.width * 0.55,map.height * 0.25);  
  map.infoWindow.setFeatures([deferred]);
  map.infoWindow.show(evt.mapPoint);
 });

Hopefully that makes sense. Good luck!
