Question

当我尝试在orderBy

中使用时，

ng-repeat功能无效

在这里，我想根据executedOn

对托管的内容进行排序

我想对元素进行排序，最新日期应该反映在顶部。

有人可以帮助我

var app = angular.module('myApp', []);

app.controller('MainCtrl', function($scope) {

    $scope.details = [
  {
    "id": 255463,
    "orderId": 226433,
    "status": 1,
    "executedOn": "25/Sep/17",
    "executedBy": "Person A",
    "executedByDisplay": "Person A",
    "cycleId": 4042,
    "cycleName": "Cycle A",
    "versionId": 21289,
    "versionName": "Version A",
    "issueKey": "A"
  },
  {
    "id": 255433,
    "orderId": 226403,
    "status": 1,
    "executedOn": "1/Mar/17",
    "executedBy": "Person B",
    "executedByDisplay": "Person B",
    "cycleId": 4041,
    "cycleName": "Cycle B",
    "versionId": 21289,
    "versionName": "Version A",
    "issueKey": "B"
  },
  {
    "id": 255432,
    "orderId": 226402,
    "status": 1,
    "executedOn": "1/Apr/17",
    "executedBy": "Person B",
    "executedByDisplay": "Person B",
    "cycleId": 4041,
    "cycleName": "Cycle B",
    "versionId": 21289,
    "versionName": "Version A",
    "issueKey": "C"
  }
];
});

th, td {
    border-bottom: 1px solid #ddd;
}

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>

        </thead>
        <tr ng-repeat="x in details | orderBy :'executedOn'">
          <td>{{$index+1}}</td>
          <td>{{x.cycleName}}</td>
          <td>{{x.executedOn | date:'d-MMM-yy'}}</td>
          <td>{{x.versionName}}</td>
        </tr>
      </table>
  </body>

Answer 1

如何将"executedOn"转换为Date对象：new Date("25/Sep/17"),

你可以这样做：

$scope.details.map(function(item){
    item.executedOn = new Date(item.executedOn);
    return item;
  });

排序将正常运作

    <tr ng-repeat="x in details | orderBy :'executedOn'">
      <td>{{$index+1}}</td>
      <td>{{x.cycleName}}</td>
      <td>{{x.executedOn | date:'d-MMM-yy'}}</td>
      <td>{{x.versionName}}</td>
    </tr>

Answer 2

您可以使用A getter函数作为orderBy表达式。将使用每个项作为参数调用此函数，并将返回值用于排序。 see details in demo

<强> JS

$scope.makerightorder = function(x){
   return new Date(x.executedOn);
}

显然使用true作为第二个参数来查看最新的

<强> HTML

<tr ng-repeat="x in details | orderBy :makerightorder:true ">
    <td>{{$index+1}}</td>
    <td>{{x.cycleName}}</td>
    <td>{{x.executedOn | date:'d-MMM-yy'}}</td>
    <td>{{x.versionName}}</td>
 </tr>

Angular JS orderBy不与Dates合作
