关闭角度模态后如何重置所有HTML输入字段

时间:2017-07-21 13:39:00

标签: javascript html angularjs

我将在文本字段中输入用户名和密码,但我不会保存。如果不保存该数据,我将关闭弹出模式。

当我点击模态外部时,它会关闭。

如果我再次打开弹出窗口,之前的数据仍然会出现。我需要清除这些数据,并希望将该字段设为空。

angular.module('plunker', ['ui.bootstrap']);
var ModalDemoCtrl = function ($scope, $modal, $log) {

    $scope.user = {
        user: 'name',
        password: null,
        notes: null
    };

    $scope.open = function () {

        $modal.open({
            templateUrl: 'myModalContent.html', // loads the template
            backdrop: true, // setting backdrop allows us to close the modal window on clicking outside the modal window
            windowClass: 'modal', // windowClass - additional CSS class(es) to be added to a modal window template
            controller: function ($scope, $modalInstance, $log, user) {
                $scope.user = user;
                $scope.submit = function () {
                    $log.log('Submiting user info.'); // kinda console logs this statement
                    $log.log(user); 
                    $modalInstance.dismiss('cancel'); // dismiss(reason) - a method that can be used to dismiss a modal, passing a reason
                }
                $scope.cancel = function () {
                    $modalInstance.dismiss('cancel'); 
                };
            },
            resolve: {
                user: function () {
                    return $scope.user;
                }
            }
        });//end of modal.open
    }; // end of scope.open function
};

问题是,您实际上将模态中的$scope.user绑定到$scope.user中的ModalDemoCtrl。要解决此问题,您应该在模态控制器中使用它之前复制user

$modal.open({
     ...
     controller: function ($scope, $modalInstance, $log, user) {
         $scope.user = angular.copy(user);
         ...
     }
});

请参阅Angular.copy()文档。

请参阅Clear the form after submit angularjs了解如何清除表单。您可以在模态关闭之前在提交函数中触发此操作。

你可以用ui bootstrap承诺来做到这一点:

$scope.modal.result.then(function(result) {
    console.log('client: resolved: ' + result);
  }, function(reason) {
    console.log('client: rejected: ' + reason);
});

我运行了你的代码并且运行正常。

angular.module('plunker', ['ui.bootstrap']);
    var ModalDemoCtrl = function ($scope, $modal, $log) {

    $scope.user = {
        user: 'name',
        password: null,
        notes: null
    };

    $scope.open = function () {

        var $theModal = $modal.open({
            templateUrl: 'myModalContent.html', // loads the template
            backdrop: true, // setting backdrop allows us to close the modal window on clicking outside the modal window
            windowClass: 'modal', // windowClass - additional CSS class(es) to be added to a modal window template
            controller: function ($scope, $modalInstance, $log, user) {
                $scope.user = user;
                $scope.submit = function () {
                    $log.log('Submiting user info.'); // kinda console logs this statement
                    $log.log(user); 
                    $modalInstance.dismiss('cancel'); // dismiss(reason) - a method that can be used to dismiss a modal, passing a reason
                }
                $scope.cancel = function () {
                    $modalInstance.dismiss('cancel'); 
                };
            },
            resolve: {
                user: function () {
                    return $scope.user;
                }
            }
        });//end of modal.open

        $theModal.result.then(function(result) {
            console.log('client: resolved: ' + result);
        }, function(reason) {
            $scope.user = {}
            console.log('client: reject: ' + reason);
        })
    }; // end of scope.open function
};
