GPS locator not working for Election Polling Place ver 2.2

BrandonVan_Horn

Hello I am trying to get the GPS locator working on this application. I keep getting "You are currently outside the supported area" dialog box. Everything but this is working. Are their any settings that have to be set to use this functionality? Thanks for your help.

I figured it out. The GPS locater was returning the location value in latitude and longitude. Therefor the location value did not fall with in the full extent value. That is because the values that are being used for the full extent are in Web Mercator Projection. Any the code to fix this is below.

Class: utls.js


navigator.geolocation.getCurrentPosition(
  function (position) {
      ShowProgressIndicator();
      mapPoint = esri.geometry.geographicToWebMercator(new esri.geometry.Point(position.coords.longitude, position.coords.latitude, new esri.SpatialReference({ wkid: 4326 }))); //Changed this line to include "esri.geometry.geographicToWebMercator("
      var graphicCollection = new esri.geometry.Multipoint(new esri.SpatialReference({ wkid: 102100 })); //changed wkid: 102100 Web Mercator
      graphicCollection.addPoint(mapPoint); //graphicCollection.addPoint(mapPoint)
      geometryService.project([graphicCollection], map.spatialReference, function (newPointCollection) {
          for (var bMap = 0; bMap < baseMapLayers.length; bMap++) {
              if (map.getLayer(baseMapLayers[bMap].Key).visible) {
                  var bmap = baseMapLayers[bMap].Key;
              }
          }
          if (!map.getLayer(bmap).fullExtent.contains(mapPoint)) {
              map.infoWindow.hide();
              selectedPollPoint = null;
              pollPoint = null;
              mapPoint = null;
              ClearSelection();
              map.getLayer(tempGraphicsLayerId).clear();
              map.getLayer(precinctLayerId).clear();
              map.getLayer(routeGraphicsLayerId).clear();
              map.getLayer(highlightPollLayerId).clear();
              HideProgressIndicator();
              if (!isMobileDevice) {
                  var imgToggle = dojo.byId('imgToggleResults');
                  if (imgToggle.getAttribute("state") == "maximized") {
                      imgToggle.setAttribute("state", "minimized");
                      WipeOutResults();
                      dojo.byId('imgToggleResults').src = "images/up.png";
                  }
              }
              ShowInfoDetailsView();
              alert(messages.getElementsByTagName("geoLocation")[0].childNodes[0].nodeValue);
              return;
          } else { //Added the else statement.
              mapPoint = newPointCollection[0].getPoint(0);
              LocateAddressOnMap(false);
          }
      });
  },
  function (error) {
      HideProgressIndicator();
      switch (error.code) {
          case error.TIMEOUT:
              alert(messages.getElementsByTagName("geolocationTimeout")[0].childNodes[0].nodeValue);
              break;
          case error.POSITION_UNAVAILABLE:
              alert(messages.getElementsByTagName("geolocationPositionUnavailable")[0].childNodes[0].nodeValue);
              break;
          case error.PERMISSION_DENIED:
              alert(messages.getElementsByTagName("geolocationPermissionDenied")[0].childNodes[0].nodeValue);
              break;
          case error.UNKNOWN_ERROR:
              alert(messages.getElementsByTagName("geolocationUnKnownError")[0].childNodes[0].nodeValue);
              break;
      }
  }, { timeout: 10000 });
}


Hope this helps someone else out. Have a great day.
