如何使用一个数组进行过滤

Question

我正在尝试 angularJS 这个例子

http://www.w3schools.com/angular/tryit.asp?filename=try_ng_filters_filter

<ul>
  <li ng-repeat="x in names | filter : 'i'">
    {{ x }}
  </li>
</ul>

但是您如何过滤多个选择？就我而言，我有一个包含所有汽车的模型。并且用户 select 来自树列表的 ID int[] SelectedCars 列表。

所以我想要类似

的东西

<ul>
  <li ng-repeat="x in names | filter : SelectedCars[]">
    {{ x }}
  </li>
</ul>

现在应该可以了。

<!DOCTYPE html>
<html>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
<body>

<div ng-app="myApp" ng-controller="namesCtrl">

<ul>
    <li ng-repeat="x in names | filter : 'i'">
        {{ x }}
    </li>
</ul>

</div>

<script>
angular.module('myApp', []).controller('namesCtrl', function($scope) {
        $scope.names = [
                'Jani',
                'Carl',
                'Margareth',
                'Hege',
                'Joe',
                'Gustav',
                'Birgit',
                'Mary',
                'Kai'
        ];
        $scope.selectedCars = [1, 2, 5];
        $scope.carsToDisplay = [];
        for (var i = 0; i < $scope.selectedCars.length; i++) {
                $scope.carsToDisplay.push($scope.names[$scope.selectedCars[i]]);
        }
        var p = document.getElementById('p');
        p.innerHTML = $scope.carsToDisplay;
});
</script>

<p id="p">This example displays only the names containing the letter "i".</p>

</body>
</html>
