Custom Directive - Order List And Property

Remember our order list from Custom Directive - Order List With Marker Type ? Well, this time we consider a list with multiple properties, like this:

{ name: 'Nadal, Rafael (ESP)', rank: 1, age: '28', prizemoney: 66149345 },
{ name: 'Djokovic, Novak (SRB)', rank: 2, age: '27', prizemoney: 70704129 },
{ name: 'Federer, Roger (SUI)', rank: 3, age: '33', prizemoney: 84827704 },
...

Now, let's suppose that we want to tell to our directive which property it should list: name, rank, age or prizemoney. So, here it is the code:

<!DOCTYPE html>
<html>
<head lang="en">
    <meta charset="UTF-8">
    <title></title>
    <script src="../angular/angular.min.js"></script>
    <style type="text/css">
    </style>
    <script>
        angular.module("appModule", [])
                .controller("appCtrl", function ($scope) {
                    $scope.players = [
                        { name: 'Nadal, Rafael (ESP)', rank: 1, age: '28', prizemoney: 66149345 },
                        { name: 'Djokovic, Novak (SRB)', rank: 2, age: '27', prizemoney: 70704129 },
                        { name: 'Federer, Roger (SUI)', rank: 3, age: '33', prizemoney: 84827704 },
                        { name: 'Wawrinka, Stan (SUI)', rank: 4, age: '29', prizemoney: 13155060 },
                        { name: 'Ferrer, David (ESP)', rank: 5, age: '32', prizemoney: 24034072 },
                        { name: 'Tsonga, Jo-Wilfried (FRA)', rank: 11, age: '29', prizemoney: 1708240 },
                        { name: 'Simon, Gilles (FRA)', rank: 26, age: '29', prizemoney: 760469 },
                        { name: 'Lopez, Feliciano (ESP)', rank: 20, age: '33', prizemoney: 1100579 },
                        { name: 'Benneteau, Julien (FRA)', rank: 28, age: '32', prizemoney: 617688 },
                        { name: 'Verdasco, Fernando (ESP)', rank: 33, age: '30', prizemoney: 689219 },
                        { name: 'Mayer, Leonardo (ARG)', rank: 25, age: '27', prizemoney: 946294 }
                    ];
                })
                .directive("orderedList", function () {
                    return function (scope, element, attrs) {
                        var data = scope[attrs["orderedList"]];
                        var marker = attrs["markerType"];
                        var property = attrs["propertyName"];
                        if (angular.isArray(data)) {
                            var listElem = angular.element("<ol type=" + marker + ">");
                            element.append(listElem);
                            for (var i = 0; i < data.length; i++) {
                                listElem.append(angular.element('<li>').text(data[i][property]));
                            }
                        }
                    }
                });
    </script>
</head>
