Question

如何更改private var _foo:Int = 0 var foo:Int { get { return _foo } set { guard newValue <= 999 else { _foo = 999 return } _foo = newValue } }中的orderBy过滤器？默认订单值是按日期（最近的第一个），但是通过点击ng-repeat，我需要按名称（字母顺序）更改排序顺序，然后如果用户再次点击 - 按日期返回订单

toggle_to_sort()

＆＃13;

angular.module('app', []).controller('ctrl', function($scope) {
  $scope.array = [
    {name: 'item1', date: 1453284120},
    {name: 'item2', date: 1453284440},
    {name: 'item3', date: 1453284550},
    {name: 'item4', date: 1453284086},
    {name: 'item5', date: 1453284330},
  ];
    
  $scope.toggle_to_sort = function() {
    // ??
  }
});

Answer 1

宣布一个标志

$scope.changeFilter=false;

然后添加此

<div ng-repeat="item in array  | orderBy: !changeFilter ? '-date' : 'name'">

更改按钮上的值

<div ng-click="changeFilter=!changeFilter"><div>

Answer 2

在你的JS中我会添加：

$scope.toggled = false;

然后在你的HTML中执行以下操作：

<div ng-repeat="item in array  | orderBy:'-date'" ng-hide="toggled">
    <div>{{item.name}}</div>
</div>

<div ng-repeat="item in array  | orderBy:'-name'" ng-show="toggled">
    <div>{{item.name}}</div>
</div>

<div ng-click="toggled=!toggled"><div>

$scope.array = [
{name: 'item1', date: 1453284120},
{name: 'item2', date: 1453284440},
{name: 'item3', date: 1453284550},
{name: 'item4', date: 1453284086},
{name: 'item5', date: 1453284330},
]
});

</div>
</body>

  </html>
