如何使用AngularJS对单击的列进行反向排序

我实现了一种对表列进行排序的简单方法，但我无法找到一种在单击和返回时反转排序的方法。有人能解决这个问题吗？下面是一把小提琴，告诉你我的意思

<div ng-app="app">

<div ng-controller="controller">

    <p>{{orderProperty}}</p>
    <div class="col-md-10">
        <table class="table table-hover table-bordered">
            <thead>
            <tr>
                <th>Status<a ng-click="orderProperty = 'a'">^</a></th>
                <th>Ref<a ng-click="orderProperty = 'b'">^</a></th>
                <th>Service<a ng-click="orderProperty = 'c'">^</a></th>
                <th>Domain<a ng-click="orderProperty = 'd'">^</a></th>
                <th>Service Owner<a ng-click="orderProperty     = 'e'">^</a></th>
                <th>Stage<a ng-click="orderProperty = 'f'">^</a></th>
            </tr>
            </thead>
            <tbody>
                <tr ng-repeat="x in projects | orderBy:orderProperty">
                    <td><b>{{x.a}}</b></td>
                    <td>{{x.b}}</td>
                    <td>{{x.c}}</td>
                    <td>{{x.d}}</td>
                        <td>{{x.e}}</td>
                        <td>{{x.f}}</td>
                    </tr>
                </tbody>
            </table>
        </div>
    </div>
</div>

{{orderProperty}}

状态
您可以通过传递
true
作为
orderBy
过滤器的第三部分来反转排序：

<tr ng-repeat="x in projects | orderBy : orderProperty : true">

在html中

更改
ng单击
调用函数

<tr>
    <th><a ng-click="sortProperty('a')">Status</a></th>
    <th><a ng-click="sortProperty('b')">Ref</a></th>
    <th><a ng-click="sortProperty('c')">Service</a></th>
    <th><a ng-click="sortProperty('d')">Domain</a></th>
    <th><a ng-click="sortProperty('e')">Service Owner</a></th>
    <th><a ng-click="sortProperty('f')">Stage</a></th>
</tr>

单击列标题将切换排序

您可以通过在列名前面加“-”来切换orderProperty。
将表格标题替换为以下代码：

<thead>
    <tr>
        <th>Status<a ng-click="setOrderProperty('a')">^</a></th>
        <th>Ref<a ng-click="setOrderProperty('b')">^</a></th>
        <th>Service<a ng-click="setOrderProperty('c')">^</a></th>
        <th>Domain<a ng-click="setOrderProperty('d')">^</a></th>
        <th>Service Owner<a ng-click="setOrderProperty('e')">^</a></th>
        <th>Stage<a ng-click="setOrderProperty('f')">^</a></th>
    </tr>
</thead>

啊，应该说得更清楚些。我想问的是，如何在单击时交替进行反向排序和正常排序。如何以十进制格式对数据进行排序。比如10.32,34.43.22.78
<thead>
    <tr>
        <th>Status<a ng-click="setOrderProperty('a')">^</a></th>
        <th>Ref<a ng-click="setOrderProperty('b')">^</a></th>
        <th>Service<a ng-click="setOrderProperty('c')">^</a></th>
        <th>Domain<a ng-click="setOrderProperty('d')">^</a></th>
        <th>Service Owner<a ng-click="setOrderProperty('e')">^</a></th>
        <th>Stage<a ng-click="setOrderProperty('f')">^</a></th>
    </tr>
</thead>

$scope.setOrderProperty = function(propertyName) {
    if ($scope.orderProperty === propertyName) {
        $scope.orderProperty = '-' + propertyName;
    } else if ($scope.orderProperty === '-' + propertyName) {
        $scope.orderProperty = propertyName;
    } else {
        $scope.orderProperty = propertyName;
    }
}
