如何存儲複選框的選定值並選擇元素並使用這些值來組合過濾結果數組？例如按類別ID過濾，或在過去的X個月中顯示所有結果。基於選中的複選框和選擇字段過濾數組
大量的研究和反覆試驗後我得儘可能的：
查看Plunker或看到下面的代碼：在「優化」指令中
HTML
<div class="filters">
<div class="filter">
<label for="maxage">Show results from</label>
<select name="maxage" id="maxage"
ng-options="option.name for option in refine.maxAge.options track by option.id"
ng-model="refine.maxAge.selected"
ng-change="filterResults()">
</select>
</div>
<div class="filter">
<div class="status-filter" ng-repeat="status in refine.statuses">
<label for="statusId{{ status.id }}">{{ status.name }}</label>
<input type="checkbox" name="status" value="{{ status.id }}" ng-change="filterResults()">
</div>
</div>

JS
var app = angular.module('app', []);
// results filter
angular.module('app').filter('results', ['$filter', function($filter) {
return function (input, refine) {
var filterParams = {};
// start off filtering with the outsideBoundary parameter
filterParams.outsideBoundary = refine.outsideBoundary;
// add 'show results from' filter
//var adjustedDate = new Date();
//adjustedDate.setMonth(adjustedDate.getMonth() - refine.maxAge.selected.id);
//filterParams.receivedDate = $filter('date')(adjustedDate, 'yyyy/MM/dd');
return $filter('filter')(input, filterParams);
}
}]);
// Controller
angular.module('app').controller('ListCtrl',
['$scope', '$filter', '$attrs', 'appService', 'resultsFilter', function ($scope, $filter, $attrs, appService, resultsFilter) {
$scope.applications = [];
$scope.refine = {
statuses: {
options: [
{ id: 1, name: 'Unknown' },
...
{ id: 6, name: 'Appealed' }
],
selected: [2, 3]
},
maxAge: {
options: [
{ id: '1', name: 'Last month' },
... // 1 to 12 months
{ id: '12', name: 'Last 12 months' }
],
selected: { id: '6', name: 'Last 6 months' }
},
...
};
$scope.filterResults = function() {
$scope.filteredResults = resultsFilter($scope.applications, $scope.refine);
};
/* get data from appService */
appService.getApplications({
status: 3,
countyparish: parseInt($attrs.countyParishId),
postcode: '',
distance: 5,
pagesize: 100
})
.then(function (data) {
$scope.applications = data;
$scope.filteredResults = resultsFilter(data, $scope.refine);
});
}]);
我很欣賞這個問題已經被問了很多次，但我還沒有找到我的問題（S）的答案，因爲大多數例子中很簡單的表達式NG-重複。
請告訴我是resultsFilter？ –
這是JS片段頂部的'結果'過濾器。根據AngularJS [docs]（https://docs.angularjs.org/guide/filter）：_「您也可以在控制器，服務和指令中使用過濾器。爲此，請將名爲的依賴項過濾到您的控制器/服務/指令，例如使用依賴項numberFilter將注入數字過濾器「_ –
