ArcGIS Javascript API Global Variable Issue

Question

I'm trying to return a string when I click on a country in a map. The string is the country name, which will then be passed to a geoprocessing tool. I've definied "country" as a global variable. I'm trying to define it inside the click function and it's not working. console.log() doesn't print anything.

Here is the code snippet:

var country = {};
map.on("click", function(evt) {
  var selectQuery = new Query();    
  selectQuery.returnGeometry = true; 
  selectQuery.geometry = geometry;
  featureLayer.selectFeatures(selectQuery, FeatureLayer.SELECTION_NEW, function(results) {
    country = results[0].attributes["NAME"];  
    console.log(country);           
  });
  map.infoWindow.setContent(content);
});

This is the solution. I needed to set the content after defining the link.

map.on("click", function uponClick(evt){

      identifyParams.geometry = evt.mapPoint;
      identifyParams.mapExtent = map.extent;
      identifyTask.execute(identifyParams, function(result) { 
         for(var i = 0; i<result.length; i++){
            country = result[i].feature.attributes["NAME"];
         } 


            var infoTemplate = new InfoTemplate();
           map.infoWindow.setTitle(country);
           map.infoWindow.show(evt.mapPoint,   
           map.getInfoWindowAnchor(evt.mapPoint))

           var link = domConstruct.create("a",{
            "class": "action", 
            "id": "reportLink",
            "innerHTML": "Generate Report",
            "href": "javascript: void(0);"
          }, query(".actionList", map.infoWindow.domNode)[0]);

          map.infoWindow.setContent(link);

i think you should listen to the click event of your featureLayer instead of the map, so you can access the attributes of the feature. something like :

var country = ''; //"{}" means object but you want a string
On(featureLayer, 'click', function (e) {
  country = e.graphic.attributes.name;
});

Add "dojo/on" as a parameter of require, ie :

require([..., "dojo/on", ...], function (..., On, ...)
