如何在AngularJS按钮单击中按按钮值过滤数据

Question

我正在尝试使用修复按钮值搜索数据，例如当我单击蔬菜按钮时，我只想蔬菜类别数据。 现在我的代码是这样的。实际上我是 Angular js 代码的新学习者。

First my button code:<butto id="veg" ng-click="myFilter = {type: 1}" title="veg">
My data display code:<div class="side-body padding-top fade in  tab-pane"  id="<?php echo $tt3->id; ?>">
                 <div class="row">
                 <div  ng-if='r.pro_category == <?php echo $tt3->id; ?>' ng-repeat = "r in groups | filter : searchGroups | filter:myFilter">
                    <div>
                        <div class="thumbnail">
                          <div><img src="../@{{r.image }}" alt="" /></div>
                          <div class="caption" style="padding-top:0px;">
                            <div>@{{r.pro_name }}</div>
                               <div>@{{r.price}}</div>
                    </div>
                    </div>
                    </div>
</div>
My script code: <script>
var GroupsApp = angular.module('GroupsApp',[]);
GroupsApp.controller('GroupsController', function ($scope, GroupsService) 
{
    getGroups();
    function getGroups() {
        GroupsService.getGroups()
            .success(function (grps) {
                $scope.groups = grps;
                 return (val.type != 2);
                console.log($scope.groups);
            })
            .error(function (error) {
                $scope.status = 'Unable to load Product data: ' + error.message;
                console.log($scope.status);
            });
    }
});
var url = window.location.pathname;
var productid = url.substring(url.lastIndexOf('/') + 1);
GroupsApp.factory('GroupsService', ['$http', function ($http) {

    var GroupsService = {};
    GroupsService.getGroups = function () {
        return $http.get('../showproduct/'+productid);
    };
    return GroupsService;
}]);
var url = window.location.pathname;
var productid = url.substring(url.lastIndexOf('/') + 1);
GroupsApp.factory('GroupsService', ['$http', function ($http) {

    var GroupsService = {};
    GroupsService.getGroups = function () {
        return $http.get('../showproduct/'+productid);
    };
    return GroupsService;
}]);
</script>

请帮助如何使用按钮单击搜索数据。

下面是示例

<div ng-app ng-controller="Test">
  <button ng-click="myFilter = {type: 1}">veg</button> | 
  <button ng-click="myFilter = {type: 2}">non veg</button> |
  <button ng-click="myFilter = null">None</button>
  <ul >
    <li ng-repeat="person in persons | filter:myFilter">{{person.name}}</li>
  </ul>
</div>

function Test($scope) {
  $scope.persons = [{type: 1, name: 'cheese'}, {type:2, name: 'chicken'}, {type:1, name: 'carrot'}, {type:2, name: 'beaf'}];
    $scope.myFunction = function(val) {
    return (val.type != 2);
    };
}
