[Titanium] JSDeferred を使って現在位置の取得を順次処理する

Titanium.include(Titanium.App.appURLToPath("app://lib/jsdeferred.js"));
Deferred.define();

var currentLocation = null;
(function() {
  var deferred = new Deferred();
  Titanium.Geolocation.addEventListener("location", function(e) {
    currentLocation = e.coords;
    deferred.call();
  });
  return deferred;
})().
next(function() {
  alert(currentLocation);
});

alert("ここは必ずしも、alert(currentLocation)の後に呼び出されるとはかぎらない!");
