如何使用 AngularJS 在单击时对列进行反向排序 [英] How to reverse sort a column on click using AngularJS

问题描述

我有一个简单的方法来对表格列进行排序，但我无法找到一种在单击和返回时反转排序之间交替的方法.有没有人对此问题有任何解决方案?下面是一个小提琴，向您展示了我的意思.

<div ng-controller="控制器"><p>{{orderProperty}}</p><div class="col-md-10"><table class="table table-hover table-bordered"><头><tr><th>状态<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>域<a ng-click="orderProperty = 'd'">^</a></th><th>服务所有者<a ng-click="orderProperty = 'e'">^</a></th><th>Stage<a ng-click="orderProperty = 'f'">^</a></th></tr></thead><tr ng-repeat="x 在项目中 | 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>

解决方案

您可以通过在列名前加上-"来切换 orderProperty.用以下代码替换您的表头:

<tr><th>状态<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>域<a ng-click="setOrderProperty('d')">^</a></th><th>服务所有者<a ng-click="setOrderProperty('e')">^</a></th><th>Stage<a ng-click="setOrderProperty('f')">^</a></th></tr></thead>

...并将此函数添加到您的范围:

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

I have a simple method of sorting the table column implemented but I can't figure out a way to alternate between reverse the sorting on click and back. Does anyone have any solutions to this issue? Below is a fiddle showing you what I mean.

<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>

解决方案

You could toggle the orderProperty by prefixing the column name with '-'. Replace your table header with this code:

<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>

... and add this function to your scope:

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