更改md-datepicker ng-model格式

问题描述

限时删除！！

我正在使用Angular Material md-datepicker . ng-model的值如下所示:"2017-04-04T22:12:51.000Z"(称为ISO格式或其他名称.)

I'm using Angular Material md-datepicker. The value of ng-model looks something like this: "2017-04-04T22:12:51.000Z" (it's called ISO format or something..)

好吧，问题是:如何创建全局配置，以便所有 md-datepicker 标签始终格式化并以某种格式解析ng-model值，例如YYYY-MM- DD?

Well, the question is: How to create a global config, so that all md-datepicker tags always format and parse the ng-model value in a certain format, let's say YYYY-MM-DD?

angular.module('MyApp')
  .controller('AppCtrl', function($scope) {
    $scope.myDate = new Date();

    $scope.minDate = new Date(
      $scope.myDate.getFullYear(),
      $scope.myDate.getMonth() - 2,
      $scope.myDate.getDate());

    $scope.maxDate = new Date(
      $scope.myDate.getFullYear(),
      $scope.myDate.getMonth() + 2,
      $scope.myDate.getDate());    })

.config(function($mdDateLocaleProvider) {
  $mdDateLocaleProvider.parseDate = function(dateString) {
    var m = moment(dateString, 'L', true);
    return m.isValid() ? m.toDate() : new Date(NaN);
  };

  $mdDateLocaleProvider.formatDate = function(date) {
    var m = moment(date);
    return m.isValid() ? m.format('L') : '';
  };
});

<div ng-app="MyApp" ng-controller="AppCtrl">
  <md-content>
    <md-datepicker ng-model="myDate" md-placeholder="Enter date"></md-datepicker>
  </md-content>

  <big>ng-model value is: <strong>{{myDate}}</strong></big>
</div>
<p>
I want to format it this way: YYYY-MM-DD
</p>

我将不胜感激！！谢谢！

I would appreciate any help!! THANKS!

推荐答案

但是，我已经通过创建自定义指令解决了我的问题.

However, I've fixed my problem by creating a custom directive.

希望这对其他一些开发人员也有帮助.

Hope this helps some other developers too.

哟！

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
  }
});
