问题描述

看到这个 Plunkr :

http://plnkr.co/edit/gSTqtxfcEjrYLt1mIzVD?p=preview

我从一个例子中得到了这个.在 https://angular-ui.github.io/bootstrap/ 给出演示日期选择器.

在标题我的日期中，当我从日期选择器中选择日期 2016-06-15 时，绑定的模型将日期显示为 2016-06-14.所以总是有 1 天的不匹配.

这篇文章视图和视图之间的角度引导日期选择器不匹配型号建议对视图应用日期过滤器.

然而，这只是一个补丁，因为当我发布到 api 时，我仍然在服务器上收到 2016-06-14.

这是一个错误还是有一些解决方法?

解决方案

我通过在模型中添加这个来解决它.

ng-model-options="{timezone: 'UTC'}"

在此处查看更新的 plunkr.

See this Plunkr :

I have taken this from an eg. given at https://angular-ui.github.io/bootstrap/ for a demo of date picker.

In the heading, My Date when I am selecting a date 2016-06-15 from the date picker, the model which is bound shows date as 2016-06-14. so always there is a mismatch of 1 day.

This post angular bootstrap datepicker mismatch between view and model suggested to apply date filter to the view.

However, it is only a patch up as when I am posting to an api, I still get 2016-06-14 on the server.

Is this a bug or is there some work around for it ?

Script : 

angular.module('ui.bootstrap.demo', ['ngAnimate', 'ui.bootstrap']);
angular.module('ui.bootstrap.demo').controller('DatepickerPopupDemoCtrl', function ($scope) {
  $scope.today = function() {
    $scope.dt = new Date();
  };
  $scope.today();



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

  $scope.inlineOptions = {
    customClass: getDayClass,
    minDate: new Date(),
    showWeeks: true
  };

  $scope.dateOptions = {
    dateDisabled: disabled,
    formatYear: 'yy',
    maxDate: new Date(2020, 5, 22),
    minDate: new Date(),
    startingDay: 1

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

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

  $scope.toggleMin();

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

  $scope.open2 = function() {
    $scope.popup2.opened = true;

    $scope.open3 = function() {
    $scope.popup3.opened = true;
  };

  $scope.setDate = function(year, month, day) {
    $scope.dt = new Date(year, month, day);
  };

  $scope.formats = ['dd-MMMM-yyyy', 'yyyy/MM/dd', 'dd.MM.yyyy', 'shortDate'];
  $scope.format = $scope.formats[0];
  $scope.altInputFormats = ['M!/d!/yyyy'];

  $scope.popup1 = {
    opened: false
  };

  $scope.popup2 = {
    opened: false

  $scope.popup3 = {
    opened: false
  };


  var tomorrow = new Date();
  tomorrow.setDate(tomorrow.getDate() + 1);
  var afterTomorrow = new Date();
  afterTomorrow.setDate(tomorrow.getDate() + 1);
  $scope.events = [
    {
      date: tomorrow,
      status: 'full'
    },

  function getDayClass(data) {
    var date = data.date,
      mode = data.mode;
    if (mode === 'day') {
      var dayToCheck = new Date(date).setHours(0,0,0,0);

      for (var i = 0; i < $scope.events.length; i++) {
        var currentDay = new Date($scope.events[i].date).setHours(0,0,0,0);

        if (dayToCheck === currentDay) {
          return $scope.events[i].status;
        }
      }
    }

    return '';
  }
});

解决方案

I solved it by adding this in the model. 

ng-model-options="{timezone: 'UTC'}"
