How to access values of an array within an array inside JSON?

Question

How can I access each value of features array within every condo and house element? I tried it like so:

attr.features.name,

... but undefined pops up in the web console.

JSON:

({condos:[{Address:'123 Fake St.', Lat:'56.645654', Lng:'23.534546', features:[{id:'1', name:'Swimming Pool'},{id:'2', name:'BBQ'},{..etc..}]},{... another condo ...},{...}],houses:[{Address:'1 Main Ave.', Lat:'34.765766', Lng:'27.8786674', features:[{...},{...}]},{... another house ...}, {...}]})

Code:

    $.each(markers, function(type, elements) {
        $.each(elements, function(index, attr){
            // if it's a house - make house marker. if it's a condo - make condo marker.
            if (type == 'houses') {
                $('#map').gmap('addMarker', { 'features': attr.features.name, 'position': new google.maps.LatLng(parseFloat(attr.lat), parseFloat(attr.lng)), 'bounds':true, 'icon':'house.png' });
            }
            else if (type == 'condos') {
                $('#map').gmap('addMarker', { 'features': attr.features.name, 'position': new google.maps.LatLng(parseFloat(attr.lat), parseFloat(attr.lng)), 'bounds':true, 'icon':'condo.png' });
            }
        });
    });

You have an object with Two Arrays. You should access each array separately

$(markers.condos).each(function(index, elem) {
    $('#map').gmap('addMarker', {
        'features': elem.features,
        'position': new google.maps.LatLng(parseFloat(elem.lat), parseFloat(elem.lng)),
        'bounds': true,
        'icon': 'condo.png'
    });
});

and same for markers.houses

But wouldn't the elem.features access both id and name of features array? I want to only access the name.

You have an array of features in your JSON. Which name would you like to access?
