AngularJS的filter，中文名“過濾器”是用來過濾變量的值，或者格式化輸出，得到自己所期望的結果或格式的東東。AngularJS中有一個filterFilter函數用來對集合過濾，非常方便。
源代碼大致如下：
function filterFilter(){return function(aray, expression comparator){if(!isArray(array)) return array;var comparatorType = typeof(comparator),predicates = [],evaluatedObjects = [];predicates.check = function(value){for(var j = 0; j < predicates.length; jii){if(!predicates[j](value){return false;})}return true;} if(comparatorType != 'function'{if(comparatorType === 'boolean' && comparator){comparator = function(obj, text){return angular.equals(obj, text);}} else {comparator = function(obj, text){...}}}) }}controller部分如下：
angular.module('app').controller('MainCtrl', ['$scope',function($scope) {$scope.users = $scope.users = [{name: '', email: '', joined: 2015-1-1}];$scope.filter = {fuzzy: '',name: ''};...}]);搜索所有任意字段
<input type="text" ng-model="filter.any" ><tr ng-repeat="user in users | filter: filter.any"><td>{{user.name}}</td><td>{{user.email}}</td><td>{{user.joined | date}}</td></tr>搜索某個字段
<input type="text" ng-model="filter.name"><tr ng-repeat="user in users | filter: filter.any| filter: {name: filter.name}"><td>{{user.name}}</td><td>{{user.email}}</td><td>{{user.joined | date}}</td></tr>如果想name字段完全匹配：
<tr ng-repeat="user in users | filter: filter.any| filter: {name: filter.name}：true"><td>{{user.name}}</td><td>{{user.email}}</td><td>{{user.joined | date}}</td></tr>搜索時間段
contrlller部分修改為：
angular.module('app').controller('MainCtrl', ['$scope',function($scope) {$scope.users = $scope.users = [{name: '', email: '', joined: 2015-1-1}];$scope.filter = {fuzzy: '',name: ''};$scope.minDate = new Date('January 1, 2000');$scope.maxDate = new Date();$scope.min = function(actual, expected) {return actual >= expected;};$scope.max = function(actual, expected) {return actual <= expected;};}]);頁面部分為：
<input type="text" ng-model="fromDate" data-min-date="{{minDate}}"><input type="text" ng-model="untilDate" data-max-date="{{maxDate}}"><tr ng-repeat="user in users | filter: filter.any| filter: {name: filter.name}| filter: {joined: untilDate}:max| filter: {joined: beforeDate}:min"><td>{{user.name}}</td><td>{{user.email}}</td><td>{{user.joined | date}}</td></tr>以上所述是小編給大家分享的Angularjs中如何使用filterFilter函數過濾的相關知識，希望對大家有所幫助。
