Adding Info Methods, Task 2/3 (Not Passing)

Seems simple but my code is not passing.

Here are the instructions:

On the next line, in app.js, use "google.maps.event.addListener()" with "marker" as the first argument, "click" as the second, and then an anonymous function as the third.

My code:

var infoWindow = new google.maps.InfoWindow({ content : "Magic Kingdom"}) 
google.maps.event.addListener(marker, "click", function(){});

Hi Dee,

Is this all the code you have? It seems there's some missing.

Can you show more so I can get a better overview of what you have?

Regards

Andrew

Hi Andrew,

Here is the full code:

var mapOptions = {
center: new google.maps.LatLng(28.42, -81.58),
zoom: 18,
mapTypeId: google.maps.MapTypeId.SATELLITE
};

var mapElement = document.getElementById("map");
var theMap = new google.maps.Map(mapElement, mapOptions);
var markers = new Array();

var geocoder = new google.maps.Geocoder();
var bounds = new google.maps.LatLngBounds();

var geocoderOptions = {address: "Magic Kingdom, Disney World"};

var markerImage;
var infoWindow = new google.maps.InfoWindow({ content : "Magic Kingdom"}) 
google.maps.event.addListener(marker, "click", function(){});

geocoder.geocode(
geocoderOptions,
function(results, status) {
    if(status == google.maps.GeocoderStatus.OK) {
        var marker = new google.maps.Marker({map: theMap, position: results[0].geometry.location});
        markers.push(marker);
        bounds.extend(results[0].geometry.location);
        theMap.fitBounds(bounds);
        infoWindow;

        }
    }
)

Thanks.

The marker is defined in the if(status == google.maps.GeocoderStatus.OK) conditional statement.

Keep the var infoWindow; where it is but the initialization of the InfoWindow and the google.maps.event.addListener line should be moved where infoWindow; is in the conditional statement.

Wow, I also mistook the instructions in step 1 to say "In line 17" instead of "In line 27" so I got this mistake.

I got excited at seeing the first instance of "infoWindow" on line 17 and only the 7 stuck I guess :P

Thanks, Andrew!
