我有三组不同的下拉菜单以及搜索框来为表格应用过滤器。如果有人在文本框(或)中输入文本,我的表格应该过滤,具体取决于在三个下拉列表中选择的值(文本框搜索和下拉搜索相互排斥)。
这是我的HTML:
<div ng-app="myModule" ng-controller="myController">
<nav class="navbar navbar-default" role="navigation">
<div class="container-fluid">
<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
<form class="navbar-form navbar-left form-horizontal" role="search">
<div class="form-group">
<label for="searchSeries" class="control-label">Find:</label>
<input type="text" id="searchSeries" ng-model="searchText" class="form-control" placeholder="Search TV Series" />
<div class="btn-group btn-input clearfix">
<button type="button" class="btn btn-default dropdown-toggle form-control" data-toggle="dropdown"> <span data-bind="label">Select One</span> <span class="caret"></span> </button>
<ul class="dropdown-menu" role="menu">
<li><a href="#" id="action">Action</a></li>
<li><a href="#" id="animation">Animation</a></li>
<li><a href="#" id="comedy">Comedy</a></li>
<li><a href="#" id="fantasy">Fantasy</a></li>
<li><a href="#" id="drama">Drama</a></li>
<li><a href="#" id="mystery">Mystery</a></li>
<li><a href="#" id="romance">Romance</a></li>

<li><a href="#" id="horror">Horror</a></li>
</ul>
</div>
<select ng-model="properties.config" ng-options="prop.value as prop.name for prop in properties.configs">
</select>
<select ng-model="order.config" ng-options="template.value as template.name for template in order.configs">
</select>
</div>
</form>
</div>
<!-- /.navbar-collapse -->
</div>
<!-- /.container-fluid -->
</nav>
<div class="container-fluid">
<div class="table-responsive">
<table class="table table-bordered">
<tbody>
<tr ng-repeat="user in users[0].tvseries | filter: searchText | filter: order.config | filter:properties.config">
<td><img ng-src="{{user.thumbnail}}" alt="" /></td>
<td><div>{{user.tv_show_name}}</div>
<div>{{user.brief_description}}</div>
<div>{{user.rating}}</div></td>
<td><div>{{user.show_time}}</div>
<div>{{user.genre}}</div>
<div>{{user.current_season}}</div>
<div>{{user.current_episode}}</div></td>
</tr>
</tbody>
</table>
</div>
</div>
</div>
我的controllers.js:
var myModule = angular.module('myModule', []);
myModule.controller('myController', function($scope, userRepository) {
userRepository.getAllUsers().success(function(users) {$scope.users = users;});
$scope.order = {};
$scope.properties = {};
//Configuration
$scope.order.configs = [
{'name': 'Ascending',
'value': 'tv_show_name'},
{'name': 'Descending',
'value': '-tv_show_name'}
];
$scope.properties.configs = [
{'name': 'Show Time',
'value': 'show_time'},
{'name': 'Rating',
'value': 'rating'}
];
//Setting first option as selected in configuration select
$scope.order.config = $scope.order.configs[0].value;
$scope.properties.config = $scope.properties.configs[0].value;
});
myModule.factory('userRepository', function($http) {
return {
getAllUsers: function() {
var url = "https://api.mongolab.com/api/1/databases/tvshowsdb/collections/tvshowsdbcollections?apiKey=e2SbmkVmLOQN-wH_ga84n9prYsgU8lQ5";
return $http.get(url);
}
};
});
请注意:当我在我的html中应用“filter:searchText”时,它运行正常,我没有遇到任何问题。但是当我尝试再应用两个过滤器“filter:order.config | filter:properties.config”时,我的代码就不会执行了。请帮我理解我出错的地方:(
答案 0 :(得分:1)
由于您要在-
之前添加和删除tv_show_name
,我认为您正在尝试sort the results by multiple fields?如果是这种情况,则语法为:
orderBy: [order.config, properties.config]
。
以下是演示:http://plnkr.co/edit/yLYQGYGcGZMqoj6yfqoT?p=preview
注意:演示是从json文件而不是mongolab api读取的,因为我需要添加重复的名称和开始时间,以显示多级排序的效果。另外,请注意我更改了选择的顺序以匹配您应用过滤器的顺序。我认为第一个选择优先于下一个选择是直观的。

如果您只想一次按其中一个选项排序,则可以使用字符串变量,就像orderBy api demo:
<div ng-click="predicate = 'tv_show_name'">Show Name ascending</div>
<div ng-click="predicate = '-tv_show_name'">Show Name descending</div>
<div ng-click="predicate = 'show_time'">Show Time</div>
<div ng-click="predicate = 'rating'">Rating</div>
...
<tr ng-repeat="user in users[0].tvseries | filter: searchText | orderBy:predicate">
以下是更新后的Demo
