我在AngularJS中的orderBy过滤器遇到麻烦.这是我的设置：
<li ng-repeat="item in listItems.data | orderBy:order">
<a ng-click="getRelated(item._id)">{{ item.title }}</a>
</li>
控制器的一部分：
$scope.order = 'year';
$scope.listItems = $http.post($scope.url,{'filterType': 'abc','letter': $scope.params.letter});
$scope.setOrder = function(order) {
$scope.order = order;
}
最后我想使用“开关”来订购数据
<span class="sort--title">Sort by</span>
<a ng-class="{true:'selected',false:''}[order=='title']" href="" ng-click="setOrder('title')" class="sort--attribute">Title</a>
<a ng-class="{true:'selected',false:''}[order=='year']" href="" ng-click="setOrder('year')" class="sort--attribute">Year</a>
<a ng-class="{true:'selected',false:''}[order=='length']" href="" ng-click="setOrder('length')" class="sort--attribute">Length</a>
<a ng-class="{true:'selected',false:''}[order=='date_added']" href="" ng-click="setOrder('date_added')" class="sort--attribute">Date Added</a>
当我点击按钮,列表没有被重新排序.
当我手动更改初始$scope.order值时,该列表按属性排序. ng-class也正确更新.我显然错过了一些东西！
解决方法
我不认为你的想法是错误的.它工作正常这是工作
plunker.
你别在别的地方出错了.
app.js
var app = angular.module('ngApp',[]);
app.controller('MainCtrl',['$scope',function ($scope) {
'use strict';
$scope.friends = [
{name: 'John',phone: '555-1276'},{name: 'Mary',phone: '800-BIG-MARY'},{name: 'Mike',phone: '555-4321'},{name: 'Adam',phone: '555-5678'},{name: 'Julie',phone: '555-8765'}
];
$scope.setOrder = function (order) {
$scope.order = order;
};
}]);
主要html
<ul class="nav nav-pills">
<li ng-class="{'active': order=='name'}"><a href="#" ng-click="setOrder('name')">name</a></li>
<li ng-class="{'active': order=='phone'}"><a href="#" ng-click="setOrder('phone')">phone</a></li>
</ul>
<ul>
<li data-ng-repeat="friend in friends|orderBy:order">
<span class="name">{{friend.name}}</span>
<span class="phone">{{friend.phone}}</span>
</li>
</ul>
