javascript - AngularJS - 将可选参数传递给模态

Question

如何将可选参数传递给我的 angularJS 模态？这是我的代码:

Controller A(触发器):

$modal.open({
  templateUrl: 'UploadPartial.html',
  controller: 'photos.uploadCtrl',
  resolve: {
    preselectedAlbum: function preselectedAlbum() {
      return angular.copy($scope.selectedAlbum);
    }
  }
});

Controller B(模态):

app.controller('photos.uploadCtrl', [
  '$scope',
  '$modalInstance',
  '$injector',
  function uploadCtrl($scope, $modalInstance, $injector) {
    if ($injector.has('preselectedAlbum')) {
      console.log('happy');  // I want this to work, but $injector doesn't find it
    } else {
      console.log('sad');  //  Always gets here instead :(
    }
  }
]);

注意:当我将 preselectedAlbum 作为依赖项时，它会起作用，但是当我没有明确传递它时，我会收到错误。我希望它是可选的。

给模态 Controller 附加一个值

angular.module('app')
    .controller('TestCtrl',TestCtrl)
    .value('noteId', null); // optional param
