我有3种类型的过滤器：
研究之一：
<div class="bar bar-subheader bar-assertive">
<label class="item-input-wrapper textbox-search">
<i class="icon ion-search placeholder-icon"></i>
<input ng-model="q" placeholder="Procurar" aria-label="filter restaurantess" />
</label>
</div>
ng-model过滤器的位置为： |过滤器：q
每个订单一个：
<!-- ORDER BY -->
<button class="button button-stable button-block icon-left ion-android-restaurant" modal-select="" ng-model="someModel" options="selectableNames" option-property="role" modal-title="Ordenar por..." has-search="true">Ordenar
<div class="option">
<h2>{{option.name}}</h2>
</div>
</button>
过滤器位于： | orderBy：someModel
我需要一个类别过滤器，它会打开一个列出所有类别的模式，但仅显示列出的类别（用户不要浪费时间选择不存在的类别）列表），这个模态的视图是：
<ion-modal view-title="cadastrar" hide-nav-bar="false">
<ion-header-bar>
<h1 class="title">Choice the Categories</h1>
</ion-header-bar>
<ion-content>
<div class="card">
<div class="item item-text-wrap">
Estão sendo listadas apenas as categorias existentes em sua localização.
</div>
</div>
<div class="button-bar">
<button class="button button-stable button-block icon-left ion-android-funnel" ng-click="save()">Aplicar Filtro</button>
</div>
<ion-list>
<ion-checkbox ng-repeat="item in ofertass | unique:'categoria_comida_nome' track by $index" ng-model="filtro[$index]" ng-true-value="{{item}}" ng-false-value="" ng-checked="check">{{item.categoria_comida_nome}}</ion-checkbox>
</ion-list>
<div class="button-bar">
<button class="button button-stable button-block icon-left ion-android-funnel" ng-click="save()">Aplicar Filtro</button>
</div>
</ion-content>
如下图所示，模态代码的结果：
订购和搜索运作良好。
但是我没有办法过滤用户选择的类别。
为了更好地说明，它遵循我的主要列表的完整视图（html），我想过滤类别：
<ion-view side="center" view-title="vovócooks">
<!-- BOTÃO CARRINHO DE COMPRAS -->
<ion-nav-buttons side="right" class="has-header">

在我的控制器中，我尝试通过点击过滤来点击摘录：
// PEGA OS ITENS SELECIONADOS NA MODAL E COLOCA NUM ARRAY
$scope.checkItems = {};
$scope.print = function () {
console.log($scope.checkItems);
}
// APLICANDO FILTRO CATEGORIA
$scope.userCategoria = function (checkItems) {
console.log("entra na chamada");
$scope.modal.hide();
};
$scope.save = function (checkItems) {
console.log("Chamou o save");
var array = [];
for (i in $scope.checkItems) {
console.log($scope.checkItems[i]);
if ($scope.checkItems[i] == true) {
array.push(i);
}
}
console.log(array);
$scope.MeuFiltro = array;
console.log("Selecionado final: "+ $scope.MeuFiltro);
window.localStorage.setItem("filtros", array);
$scope.modal.hide();
}
我已经做了很多测试，这很糟糕......
但是你可以看到我获取数据，并以逗号分隔本地存储：
那就是我很痛苦返回（无知）......
如果我发布 | GroupBy：'mais_campo' 会出错。
我无法按类别进行过滤，我需要帮助。
或者我是否需要更改逻辑？我不知道是否缺少更好的逻辑（或知识）。 非常感谢......
嗯，为了完成，我提供我的整个控制器：

感谢您的时间。对不起我的英文......
修改
我认为错误就在这里：
<div class="card" ng-repeat="item in ofertass | filter:q | orderBy:someModel | unique: 'cadastra_oferta_cod_oferta'" ng-init="$last ? fireEvent() : null" href="#/nhaac/ofertas_singles/{{item.cadastra_oferta_cod_oferta}}">
因为现在我可以获得如下数组： [“Temakes”，“Cozinha Vegetariana”]
但是， 如何在此ng-repeat中添加更多此过滤器？ 我通过 MeuFiltro调用的数组：
$scope.save = function (checkItems) {
console.log("Chamou o save");
var array = [];
for (i in $scope.checkItems) {
console.log($scope.checkItems[i]);
if ($scope.checkItems[i] == true) {
array.push(i);
}
}
console.log(array);
$scope.MeuFiltro = array;
window.localStorage.setItem("filtros", array);
$scope.modal.hide();
}
答案 0 :(得分：0)
我无法理解完整的问题。
但是，您可以尝试在类别中使用所选变量，当用户选择类别时，它将变为true。
在要显示隐藏的部分中，只需使用过滤器|选择
