                        </span>
                    </p>
                </div>
            </form>

        </div>
        <div class="modal-footer">
            <button class="btn btn-primary" ng-click="ok()">OK</button>
            <button class="btn btn-warning" ng-click="cancel()">Cancel</button>
        </div>
    </script>
</div>

使用Javascript

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

  $scope.open_modal = function(notification) {

        $scope.selectedNotification = notification;
        var modalInstance = $modal.open({
            templateUrl: 'notificationInput.html',controller: ModalInstanceCtrl,scope: $scope
        });
    };
};

var ModalInstanceCtrl = function ($scope,$modalInstance) {

    $scope.ok = function () {
        $modalInstance.close();
    };

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

    $scope.today = function() {
        $scope.dt = new Date();
    };
    $scope.today();

    $scope.clear = function () {
        $scope.dt = null;
    };

    // Disable weekend selection
    $scope.disabled = function(date,mode) {
        return ( mode === 'day' && ( date.getDay() === 0 || date.getDay() === 6 ) );
    };

    $scope.toggleMin = function() {
        $scope.minDate = $scope.minDate ? null : new Date();
    };
    $scope.toggleMin();

    $scope.open = function($event) {
        $event.preventDefault();
        $event.stopPropagation();

        $scope.opened = true;
    };

    $scope.dateOptions = {
        formatYear: 'yy',startingDay: 1
    };

    $scope.initDate = new Date('2016-15-20');
    $scope.formats = ['dd-MMMM-yyyy','yyyy/MM/dd','dd.MM.yyyy','shortDate'];
    $scope.format = $scope.formats[0];

};
