代码：

<div ng-app="myApp" ng-controller="myCtrl"><p ng-repeat="x in items | unique:'id'">{{x.id}}---{{x.name}}</p>
</div>
<script>//AngularJs 自定义过滤器//1.使用过滤器，去除重复angular.module('common', []).filter('unique', function () {return function (collection, keyname) {console.info(collection);console.info(keyname);var output = [],keys = [];angular.forEach(collection, function (item) {var key = item[keyname];if (keys.indexOf(key) === -1) {keys.push(key);output.push(item);}});return output;}});var app = angular.module('myApp', ['common']);app.controller('myCtrl', function ($scope) {//$scope.items = [1, 2, 3,2];//当前unique 的过滤只针对，对象数组过滤$scope.items = [{ id: 1, name: 'zhangsan' },{ id: 2, name: 'lisi' },{ id: 1, name: 'zhangsan' },];});
</script>

结果：
