UI Bootstrap Datepicker 弹出日期格式

Question

我正在使用 UI Bootstrap 日期选择器弹出窗口，我想使用自定义日期格式。我的休息服务以 'dd/MM/yyyy' 格式向我发送日期。我想使用这种格式，但在更改模型值时，日期选择器不会更新。我定义了 uib-datepicker-popup="dd/MM/yyyy" 但似乎不起作用。

angular.module('ui.bootstrap.demo', ['ngAnimate', 'ngSanitize', 'ui.bootstrap']);
angular.module('ui.bootstrap.demo').controller('DatepickerPopupDemoCtrl', function ($scope) {
  $scope.today = function() {
    $scope.dt = '02/01/2017';
  };

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

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

  $scope.open1 = function() {
    $scope.popup1.opened = true;
  };

  $scope.popup1 = {
    opened: false
  };
});

关于 plunker： - 单击 "today"，使 $scope.dt = '02/01/2017' - 打开日期选择器弹出窗口，它在 2 月 1 日而不是 1 月 2 日初始化

Answer 1

UI Bootstrap datepicker 公开它在内部用作服务的日期解析器。将 uibDateParser 服务注入您的控制器并使用解析函数将您的日期转换为正确的格式：

function ($scope, uibDateParser) {
  $scope.today = function() {
    $scope.dt = uibDateParser.parse('02/01/2017', 'dd/MM/yyyy');
  };
...
}

经过一些研究，我想我正在寻找一个指令来添加自定义解析器和格式化程序：

.directive('dateFormatter', [
    function () {
        return {
            restrict: 'A',
            require: 'ngModel',
            link: function postLink(scope, element, attrs, ngModel) {
              ngModel.$parsers.push(function(data) {
                return moment(data).format('DD/MM/YYYY');
              });

              ngModel.$formatters.push(function(data) {
                return moment(data, 'DD/MM/YYYY').toDate()
              });
            }
        };
    }
]);
