我想通過變量提供過濾器值。我試圖包含模型引用{{fil}}的ng-repeat行出現了什麼問題?AngularJS過濾器語法
<!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 : {{fil}}">
{{ x }}
</li>
</ul>
<p>This example displays only the names containing the letter {{ fil }}.</p>
</div>
<script>
angular.module('myApp', []).controller('namesCtrl', function($scope) {
$scope.names = [
'Jani',
'Carl',
'Margareth',
'Hege',
'Joe',
'Gustav',
'Birgit',
'Mary',
'Kai'
];
$scope.fil = "a";
});
</script>
</body>
