Dynamic orderBy in AngularJS

Question

I have an array of objects I want to order dynamically, based on a value from a drop down menu. This is what I have so far in my list:

ng-repeat=\"item in fi         


        

Answer 1

Update orderBy:myCalculatedValueFunction to something like orderBy:dynamicOrderFunction:

ERRONEOUS

$scope.dynamicOrderFunction = function() {
    if (orderByString) {
        return '-creationDate';
    }
    else {
        return myCalculatedValueFunction;
    }
}

orderBy also has a 3rd property that accepts a boolean and will reverse orderBy when true. (orderBy:dynamicOrderFunction:reverseOrder where $scope.reverseOrder = true; // or false)

You will actually run into issues trying to switch orderBy between a string a function this way. Checkout out this jsfiddle for a working dynamic order function.

$scope.dynamicOrder = function(user) {
    var order = 0;
    switch ($scope.order.field) {
        case 'gender':
            order = gender_order[user.gender];
            break;
        default:
            order = user[$scope.order.field];
    }
    return order;
}
