如何存储复选框的选定值和选择元素并使用它们的组合来过滤结果数组？例如考虑按类别 ID 进行过滤，或显示过去 X 个月内的所有结果。
经过大量研究和反复试验，我得到了这样的结果:
查看 Plunker 或查看下面的代码:
“refine”指令中的 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>
</div>
主页的 HTML
<body ng-app="app">
<div ng-controller="ListCtrl" data-county-parish-id="1478">
...
<main class="page-content columns medium-9 medium-push-3">
...
<spinner name="planningSpinner" show="true">
<div class="loadingPanel block"></div>
</spinner>
<div class="planning">
<div class="no-results ng-hide" ng-show="filteredResults.length === 0">
<p>No results.</p>
</div>
<h4>Number of records: {{ filteredResults.length }}</h4>
<div ng-repeat="appl in filteredResults">
<hf-application info="appl"></hf-application>
</div>
</div>
...
</main>
<aside class="sidebar columns medium-3 medium-pull-9">
...
<div hf-refine-results info="refine"></div>
</aside>
...
</div>
</body>
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, $scope.refine);
});
}]);
我很高兴这个问题已经被问了很多次，但是我还没有找到我的问题的答案，因为大多数示例都是 ng-repeat 中非常简单的表达式。
最佳答案
此示例适用于多个复选框。对于使用外部选择进行过滤，请使用相同的逻辑。看看
'use strict';
var App = angular.module('clientApp', ['ngResource', 'App.filters']);
App.controller('ClientCtrl', ['$scope', function ($scope) {
$scope.selectedCompany = [];
$scope.companyList = [{
id: 1,
name: 'Apple'
}, {
id: 2,
name: 'Facebook'
}, {
id: 3,
name: 'Google'
}];
$scope.clients = [{
name: 'Brett',
designation: 'Software Engineer',
company: {
id: 1,
name: 'Apple'
}
}, {
name: 'Steven',
designation: 'Database Administrator',
company: {
id: 3,
name: 'Google'
}
}, {
name: 'Jim',
designation: 'Designer',
company: {
id: 2,
name: 'Facebook'
}
}, {
name: 'Michael',
designation: 'Front-End Developer',
company: {
id: 1,
name: 'Apple'
}
}, {
name: 'Josh',
designation: 'Network Engineer',
company: {
id: 3,
name: 'Google'
}
}, {
name: 'Ellie',
designation: 'Internet Marketing Engineer',
company: {
id: 1,
name: 'Apple'
}
}];
$scope.setSelectedClient = function () {
var id = this.company.id;
if (_.contains($scope.selectedCompany, id)) {
$scope.selectedCompany = _.without($scope.selectedCompany, id);
} else {
$scope.selectedCompany.push(id);
}
return false;
};
$scope.isChecked = function (id) {
if (_.contains($scope.selectedCompany, id)) {
return 'icon-ok pull-right';
}
return false;
};
$scope.checkAll = function () {
$scope.selectedCompany = _.pluck($scope.companyList, 'id');
};
}]);
angular.module('App.filters', []).filter('companyFilter', [function () {
return function (clients, selectedCompany) {
if (!angular.isUndefined(clients) && !angular.isUndefined(selectedCompany) && selectedCompany.length > 0) {
var tempClients = [];
angular.forEach(selectedCompany, function (id) {
angular.forEach(clients, function (client) {
if (angular.equals(client.company.id, id)) {
tempClients.push(client);
}
});
});
return tempClients;
} else {
return clients;
}
};
