Javascript 如何在1.5版angularjs中使用$resource取消承诺

我正在使用angular 1.5.7，如果需要时间，我想取消对资源的删除。我使用的是平均堆栈，有时我会看到我的资源上的删除被视为挂起（是mongo慢吗？）。 下面是我调用delete的控制器的工厂和代码段： *工厂：

      .factory('addressesFactory', ['$resource', 'baseURL', function ($resource, baseURL) {
    return $resource(baseURL + 'addresses/:id', {id: '@_id'}, {
      'update': {
        method: 'PUT'
      },
      'delete': {
        method: 'DELETE'
      }
    });
  }])

• 控制器中的代码段：

  $scope.delete = function (address, addressesList) {
  
  $scope.deleteDisabled=true;
  
  console.log('[ModeratorsCtrl] Deleting:' + address.name);
  console.log('[ModeratorsCtrl] ' + addressesList.length);
  addressesFactory.delete({id: address._id}).$promise.then(
    function (response) {
      $scope.deleteDisabled=false;
      console.log('[ModeratorsCtrl] Address deleted successfully');
    },
    function (response) {
      $scope.deleteDisabled=false;
      var message = '[ModeratorsCtrl] Error: ' + response.status + ' ' + response.statusText;
      console.log(message);
    }
  );
  

   $scope.delete = function (address, addressesList) {
      $scope.deleteDisabled = true;//prevent multiple click
  
      var deleteRequest = addressesFactory.delete({id: address._id});
      deleteRequest.$promise.then(
        function (response) {
          $scope.deleteDisabled = false;
          console.log('[ModeratorsCtrl] Address deleted successfully');
        },
        function (response) {
          $scope.deleteDisabled = false;
          var message = '[ModeratorsCtrl] Error: ' + response.status + ' ' + response.statusText;
          console.log(message);
        }
      );
  
      $timeout(function () {//2 seconds then cancel the promise
        if ($scope.deleteDisabled === true) {
          console.log('[ModeratorsCtrl] Cancel ...');
          deleteRequest.$cancelRequest();
          $scope.deleteDisabled = false;
        }
      }, 2000);
    };
  

  })

我看了这篇文章，读了这篇关于取消请求的文章：$resource#！使用$cancelRequest（），但我有点困惑。 有谁能告诉我如何在实施过程中取消承诺的最佳实践吗？

关于，

假设您的资源是

用户

，要取消请求，您应该命名您的操作，例如

var request = Users.query();

在这一点上，请求就是承诺。你可以简单地做一个

request.$cancelRequest();

取消。

谢谢您的帮助 我在工厂里做了以下工作：

  .factory('addressesFactory', ['$resource', 'baseURL', function ($resource, baseURL) {
    return $resource(baseURL + 'addresses/:id', {id: '@_id'}, {
      'update': {
        method: 'PUT'
      },
      'delete': {
        method: 'DELETE',
        cancellable: true
      }
    });
  }])

然后在我的控制器中：

$scope.delete = function (address, addressesList) {

$scope.deleteDisabled=true;

console.log('[ModeratorsCtrl] Deleting:' + address.name);
console.log('[ModeratorsCtrl] ' + addressesList.length);
addressesFactory.delete({id: address._id}).$promise.then(
  function (response) {
    $scope.deleteDisabled=false;
    console.log('[ModeratorsCtrl] Address deleted successfully');
  },
  function (response) {
    $scope.deleteDisabled=false;
    var message = '[ModeratorsCtrl] Error: ' + response.status + ' ' + response.statusText;
    console.log(message);
  }
);

 $scope.delete = function (address, addressesList) {
    $scope.deleteDisabled = true;//prevent multiple click

    var deleteRequest = addressesFactory.delete({id: address._id});
    deleteRequest.$promise.then(
      function (response) {
        $scope.deleteDisabled = false;
        console.log('[ModeratorsCtrl] Address deleted successfully');
      },
      function (response) {
        $scope.deleteDisabled = false;
        var message = '[ModeratorsCtrl] Error: ' + response.status + ' ' + response.statusText;
        console.log(message);
      }
    );

    $timeout(function () {//2 seconds then cancel the promise
      if ($scope.deleteDisabled === true) {
        console.log('[ModeratorsCtrl] Cancel ...');
        deleteRequest.$cancelRequest();
        $scope.deleteDisabled = false;
      }
    }, 2000);
  };

希望这是最好的做法，请随时反馈。

这是最新的一个：感谢您提供的链接，关于如何在我的情况下使用$cancelRequest（）有什么想法吗？好的，谢谢，我会尝试一下，我想我必须在控制器中的delete调用之后执行这样的调用：AddresssFactory。$cancelRequest（）；假设我在我的工厂中设置了Cancelable:true，请确保通过在资源上设置

Cancelable:true

，否则

$cancelRequest（）

方法将不会公开。
