object - 在ng Repeat中对哈希对象的值进行排序-angularJS

Question

我有一个这样的对象:

$scope.phones = new Object();
$scope.phones['id1'] = {
    "name":"Phone Name1",
    "dateReleased":"2012-1-09 15:48:24"
};
$scope.phones['id2'] = {
    "name": "Phone Name2",
    "dateReleased":"2012-3-12 15:32:11"
};
$scope.phones['id3'] = {
    "name": "Phone Name3",
    "dateReleased":"2012-2-10 13:53:32"
};

我正在使用ngRepeat显示它。我无法按 dateReleased进行订购。另外，反向排序不起作用。我的ngRepeat看起来是这样的:

<li ng-repeat="phone in phones | orderBy:dateReleased:true">
    <p>{{phone.name}}</p>
    <p>{{phone.dateReleased}}</p>
</li>

Answer 1

如果您检查documentation，则表示orderBy的表达式可以是函数，字符串或数组。因此，您需要 dateReleased 作为字符串:'dateReleased'

另外，您还需要将手机对象设置为实际的数组。

尝试:

$scope.phones = [{
        "name":"Phone Name1",
        "dateReleased":"2012-1-09 15:48:24"
    },{
        "name": "Phone Name2",
        "dateReleased":"2012-3-12 15:32:11"
    },{
        "name": "Phone Name3",
        "dateReleased":"2012-2-10 13:53:32"
    }];

<li ng-repeat="phone in phones | orderBy:'dateReleased':true">
    <p>{{phone.name}}</p>
    <p>{{phone.dateReleased}}</p>
</li>
