AngularJS - filter for undefined properties in ng-repeat?

Question

For my AngularJS project (v1.2.3), I have a list of routes and am trying to build a navigation bar from the object. What I want to do is display any object with an undefined

Answer 1

module.filter('notNullOrUndefined', [function () {
    return function (items, property) {
        var arrayToReturn = [];
        for (var i = 0; i < items.length; i++) {
            var test = property !== undefined ? items[i][property] : items[i];
            if (test !== undefined && test !== null) {
                arrayToReturn.push(items[i]);
            }
        }
        return arrayToReturn;
    };
}]);

Usage:

    {{style.name}} Background
