我正在使用Angular-Filter的groupBy过滤器。
来自GitHub的示例 :
$scope.players = [ {name: 'Gene', team: 'alpha'}, {name: 'George', team: 'beta'}, {name: 'Steve', team: 'gamma'}, {name: 'Paula', team: 'beta'}, {name: 'Scruath', team: 'gamma'} ]; <ul> <li ng-repeat="(key, value) in players | groupBy: 'team'"> Group name: {{ key }} <ul> <li ng-repeat="player in value"> player: {{ player.name }} </li> </ul> </li> </ul>
因此,该示例按 team 对玩家集合进行 分组 。想象一下,每个玩家对象都有一个 年龄 属性:
$scope.players = [ {name: 'Gene', team: 'alpha', age: 19}, {name: 'George', team: 'beta', age: 19}, {name: 'Steve', team: 'gamma', age: 23}, {name: 'Paula', team: 'beta', age: 23}, {name: 'Scruath', team: 'gamma', age: 23} ];
我想GROUP BY 团队 和 年龄 。我怎样才能做到这一点?
遵循多个字段的示例
angular.module('app',['angular.filter']) .controller('MainController', function($scope) { $scope.players = [ {name: 'Gene', team: 'alpha', age: 19}, {name: 'George', team: 'beta', age: 19}, {name: 'Steve', team: 'gamma', age: 23}, {name: 'Paula', team: 'beta', age: 23}, {name: 'Scruath', team: 'gamma', age: 23} ]; }); <!DOCTYPE html> <html ng-app="app"> <head> <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.22/angular.min.js"></script> <script src="//cdnjs.cloudflare.com/ajax/libs/angular-filter/0.4.7/angular-filter.js"></script> <meta name="description" content="[groupBy example]"/> <meta charset="utf-8"> <title>JS Bin</title> </head> <body> <div ng-controller="MainController"> <ul ng-repeat="(key, value) in players | groupBy: '[team,age]'"> <b>Group name: {{key}}</b> <br> <li ng-repeat="player in value"> <b>player:</b> {{ player.name }} <br> <b>team:</b> {{player.team}} <br> <span ng-if="player.age"><b>age:</b> {{ player.age }}</span> </li> </ul> </div> </body> </html>
