日期选择器格式不影响ng-model Angular Material

Question

我想在我的ng-model中使用此格式['DD-MM-YYYY']格式DatePicker。

我在config（）

中这样做了

function showSideBarUserInterface()
{
   var html = HtmlService.createTemplateFromFile(
        'SideBarUserInterface').evaluate()
        .setWidth(400)
        .setTitle("What would you like to do?")
        .setSandboxMode(HtmlService.SandboxMode.IFRAME);
    var ss = SpreadsheetApp.getActive();
    SpreadsheetApp.getUi().showSidebar(html);
}

并在视图和日志中返回有效的日期格式。

但这不会影响ng-model变量

$mdDateLocaleProvider.formatDate = function(date) {
  var newDateFormate =   moment(date).format('DD-MM-YYYY');  
            return newDateFormate ; 
};

因为如果记录这个变量，它会给我这个日期格式

 <md-datepicker ng-model="user.bod" md-placeholder="Enter birth date "> </md-datepicker>

Answer 1

ng-model值是js Date对象。使用服务来模拟模型值：

var dateString = $mdDateLocale.formatDate(valueFromNgModel);

angular.module('MyApp')

.controller('AppCtrl', function($scope) {
  $scope.person = {
    name: "John",
    birthDate: "1990-01-01 00:00:00"
  };
})

.directive('mdDatepicker', function () {
  function link(scope, element, attrs, ngModel) {
    var parser = function (val) {
      val = moment(val).format('YYYY-MM-DD hh:mm:ss');
      return val;
    };
    var formatter = function (val) {
      if (!val) return val;
      val = moment(val).toDate();
      return val;
    };
    ngModel.$parsers.push(parser);
    ngModel.$formatters.push(formatter);
  }
  return {
    require: 'ngModel',
    link: link,
    restrict: 'EA',
    priority: 1
  }
});
