我有一个简单的示例，我希望我的段落根据唯一年龄过滤掉值，但我收到了未知提供者错误。如何 ？
<html>
<head>
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.4.8/angular.min.js"></script>
</head>
<body ng-app="myApp" ng-controller="myCtrl">
<p ng-repeat="x in persons | unique: 'age'">{{x.name}}</p>
<script>
//App declaration
var app = angular.module('myApp',[]);
//Controller Declaration
app.controller('myCtrl',function($scope){
$scope.persons = [{name: "Peter",age:23},{name:"Laila",age:25},{name:"Rosy",age:23}];
});
</script>
</body>
</html>
最佳答案
您需要将“ui.directives”和“ui.filters”模块注入(inject)您的应用
var app = angular.module('myApp',['ui.directive', 'ui.filters']);
由于 ui.directives 和 ui.filters 模块存在于 AngularUI 中，您还需要在应用程序中引用 angular-ui.js
<script src="http://cdnjs.cloudflare.com/ajax/libs/angular-ui/0.4.0/angular-ui.min.js"></script>
你的完整代码应该是这样的
<html>
<head>
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.4.8/angular.min.js"></script>
<script src="http://cdnjs.cloudflare.com/ajax/libs/angular-ui/0.4.0/angular-ui.min.js"></script>
</head>
<body ng-app="myApp" ng-controller="myCtrl">
<p ng-repeat="x in persons | unique: 'age'">{{x.name}}</p>
<script>
//App declaration
var app = angular.module('myApp',['ui.directives','ui.filters']);
//Controller Declaration
app.controller('myCtrl',function($scope){
$scope.persons = [{name: "Peter",age:23},{name:"Laila",age:25},{name:"Rosy",age:23}];
});
</script>
</body>
</html>
