在没有背景的情况下单击鼠标关闭 ui-bootstrap 模态

Question

我目前正在将 ui-bootstrap 从 0.5.0 迁移到 0.14.3（是的，我已经很久没有检查更新了）。在 0.5.0 中有一个带有 'options' 配置对象的 'modal' 指令。有一个 'backdropClick' 选项，它允许在窗口外单击鼠标时关闭窗口。在 0.14.3 中 $uibModal 服务没有这样的选项。它有一个 'backdrop' 属性，可以设置为 'static'，允许您通过单击鼠标关闭模态框，但模态框有背景。如果没有呢？ 'backdrop' 属性设置为 'false' 时，我可以单击鼠标关闭它吗？

这个缺失的功能有一个解决方法。您可以使用指令检测 "click outside" 事件，然后在相关事件中调用关闭模式方法。

在下面的示例中（改编自 ui.bootstrap 文档）我使用了 angular-click-outside directive:

angular.module('ui.bootstrap.demo', ['ngAnimate', 'ui.bootstrap','angular-click-outside']);
angular.module('ui.bootstrap.demo').controller('ModalDemoCtrl', function ($scope, $uibModal, $log, $document) {

  $scope.items = ['item1', 'item2', 'item3'];

  $scope.animationsEnabled = true;
  
  $document.on('click', function(event) {
    
  });

  $scope.open = function (size) {

    var modalInstance = $uibModal.open({
      animation: $scope.animationsEnabled,
      templateUrl: 'myModalContent.html',
      controller: 'ModalInstanceCtrl',
      backdrop: false,
      size: size,
      resolve: {
        items: function () {
          return $scope.items;
        }
      }
    });

    modalInstance.result.then(function (selectedItem) {
      $scope.selected = selectedItem;
    }, function () {
      $log.info('Modal dismissed at: ' + new Date());
    });
  };

  $scope.toggleAnimation = function () {
    $scope.animationsEnabled = !$scope.animationsEnabled;
  };

});

// Please note that $modalInstance represents a modal window (instance) dependency.
// It is not the same as the $uibModal service used above.

angular.module('ui.bootstrap.demo').controller('ModalInstanceCtrl', function ($scope, $uibModalInstance, items) {

  $scope.items = items;
  $scope.selected = {
    item: $scope.items[0]
  };

  $scope.ok = function () {
    $uibModalInstance.close($scope.selected.item);
  };

  $scope.cancel = function () {
    $uibModalInstance.dismiss('cancel');
  };
});
