Question

我使用Angular UI bootstrap模式，遇到了一些问题。

我想在bootstrap模态消除动画完成时调用一个函数。一旦模态开始被解除，下面的代码块将调用cancel（）函数 - 而不是当模态消除动画完成时。

Angular UI不使用事件，因此没有＆＃39; hidden.bs.modal＆＃39;被解雇的事件（至少，据我所知）。

var instance = $modal.open({...});

instance.result.then(function(data) {
            return success(data);
        }, function() {
            return cancel();
        })

当模态开始关闭时，cancel（）块立即运行。我需要在Bootstrap模式的关闭动画完成时执行代码。

如何通过角度UI实现这一目标？

有点晚了，但希望它仍然有帮助！您可以劫持uib-modal-window指令并检查其范围何时被销毁（它是一个独立的范围指令）。最终从文档中删除模态时，范围将被销毁。我还会使用服务来封装功能：

<强>服务

app.service('Modals', function ($uibModal, $q) {
  var service = this,
      // Unique class prefix
      WINDOW_CLASS_PREFIX = 'modal-window-interceptor-',
      // Map to save created modal instances (key is unique class)
      openedWindows = {};

  this.open = function (options) {
    // create unique class
    var windowClass = _.uniqueId(WINDOW_CLASS_PREFIX);

    // check if we already have a defined class
    if (options.windowClass) {
      options.windowClass += ' ' + windowClass;
    } else {
      options.windowClass = windowClass;
    }

    // create new modal instance
    var instance = $uibModal.open(options);

    // attach a new promise which will be resolved when the modal is removed
    var removedDeferred = $q.defer();
    instance.removed = removedDeferred.promise;

    // remember instance in internal map
    openedWindows[windowClass] = {
      instance: instance,
      removedDeferred: removedDeferred
    };
    return instance;
  };

  this.afterRemove = function (modalElement) {
    // get the unique window class assigned to the modal
    var windowClass = _.find(_.keys(openedWindows), function (windowClass) {
        return modalElement.hasClass(windowClass);
      });

    // check if we have found a valid class
    if (!windowClass || !openedWindows[windowClass]) {
      return;
    }

    // get the deferred object, resolve and clean up
    var removedDeferred = openedWindows[windowClass].removedDeferred;
    removedDeferred.resolve();
    delete openedWindows[windowClass];
  };

  return this;
});

<强>指令

app.directive('uibModalWindow', function (Modals) {
  return {
    link: function (scope, element) {
      scope.$on('$destroy', function () {
        Modals.afterRemove(element);
      });
    }
  }
});

并在控制器中使用它，如下所示：

app.controller('MainCtrl', function ($scope, Modals) {
  $scope.openModal = function () {
    var instance = Modals.open({
      template: '<div class="modal-body">Close Me</div>' +
        '<div class="modal-footer"><a class="btn btn-default" ng-click="$close()">Close</a></div>'
    });

    instance.result.finally(function () {
      alert('result');
    });

    instance.removed.then(function () {
      alert('closed');
    });
  };
});

我还写了一篇关于它的博客文章here。
