javascript - 如何在 ng-repeat 中触发功能

Question

我试图从 ng-repeat 中的第二个查询中计算数组长度。

这是我的html：

<tbody>
    <tr ng-repeat="j in jobpositions | filter:searchString | orderBy:'startdate'">
        <td ng-init="applications(j.id)">{{jobapplicationsperjob.length}}</td>
    </tr>
</tbody>

这是功能：

$scope.applications = function(jid){
    var JobapplicationsPerJob = $resource('/ats/services/jobapplicationsperjob/:jid');
        $scope.jobapplicationsperjob = JobapplicationsPerJob.query({jid:jid});
        console.log($scope.jobapplicationsperjob);
    }

这是控制台日志：

[$promise: Object, $resolved: false]
    0: f
    $promise: Object
    $resolved: true
    length: 1
    __proto__: Array[0]
[$promise: Object, $resolved: false]
    $promise: Object
    $resolved: true
    length: 0
    __proto__: Array[0]
[$promise: Object, $resolved: false]
    $promise: Object
    $resolved: true
    length: 0
    __proto__: Array[0]

如您所见，它两次返回值 1，但在 HTML 中它始终为 0。
