I have an angular 1.5 application where i make use of a moment datepicker library from here : angular moment date picker
Everything has worked well until recently when we realized that the date pickers rendered dates wrongly across different user pc's .It appears this may have something to do with how JavaScript handles time zones:
In the image below October 1, 2017 is actually a Sunday but the date picker renders it as a Monday albeit I get the correct values rendered on my own pc running a more current version of google chrome perhaps this is also a browser issue ?
IE does show dates as I would expect.
see the html snippet for the input below:
<input class="form-control input-sm"
ng-model="vm.form.StartDateTime"
format="DD-MMM-YYYY, HH:mm:ss"
ng-model-options="{ updateOn: 'blur' }"
start-view="month"
moment-picker="vm.form.StartDateTime" />
JS: moment(self.form.StartDateTime)
The primary question is how can I ensure date-times are represented correctly across different time zones on the date picker ?

I am using the Angular Moment Picker library and trying to set a custom date in the input field whilst also trying to prevent the user from selecting a date in the past.
My element looks like so:
<input class="form-control"
moment-picker="endTimePicker"
name="campaignEndDate"
locale="en"
format="MMMM Do YYYY, h:mm A"
today="true"
start-view="month"
min-date="minDate"
ng-model="endTime"
ng-model-options="{ updateOn: 'blur' }"
ng-required="!campaign.NeverEnds"
style="width: 60%;"/>
And my controller:
$scope.minDate = moment();
$scope.endTime = moment( $scope.campaign.EndTime );
When I open the form, the Angular Moment Picker shows today's date/time in the input field, even though $scope.endTime is showing a date in the past.
The only way I can seem to get the correct date showing in the input field is to set validate="false" on the element, but then the control doesn't pass validation because the date is a date in the past.
What I am trying to achieve is to show an initial date (2020-07-29 02:14:00) when the user opens the form, but if they try and change the endTime, then cannot select a new date in the past.
Is this achievable somehow?
Okay, after playing around with this some more, and going back over the documentation, I found the best approach to achieve what I wanted was to implement a selectable method:
angular-moment-picker#methods
I removed the min-date="minDate" which allowed the Moment Picker to then show the correct date in the input field and then added a selectable="isSelectable( date )" to the element to filter out and disable any previous days:
$scope.isSelectable = function( date ) {
// Disable all previous days
return date >= moment();
};
Here's my html code:
<label>D.O.B: </label>
<input type="date" ng-model="dob">
In the Browser, datepicker pops up, when I pick a particular date and try to display, both date and time are displayed,something like this "2016-04-02T18:30:00.000Z".
My question is what should I do, so that only Date gets saved(i.e. excluding time)?
In Javscript there is no Date-only type. So instances new Date() always contain time. You should ignore them in code where you treat it.
When date is displayed in angular app you can use a filter, ex.:
<div>value = {{dob | date: "yyyy-MM-dd"}}</div>
As an option you can zero time part by dob = dob.getDate() before sending it somewhere...
In my project I am using angularJS and momentJS for fixing the painful date formating part. I have two scenarios, here we go:
Retrieving the date from db and rendering it in UI:
I am getting the response from service in this formate "2016-01-31T20:30:00.000Z". I am using the above and rendering the date and time separately in the following way in UI
<input ng-model="data.startDate" type="date" name="startDate" disabled>
<input ng-model="data.startDate" type="time" name="startTime" disabled>
Its displaying like the image attached below
Its being displayed as YYYY-MM-DD in firefox and in the chrome as DD-MM-YYYY. I want to use the same object for displaying the date and time maintaining the date formate across all the browsers. How it can be achieved ?
I am using this datepicker. When the user selects the date I want show the date in the same format. In this scenario date and time inputs are taken separately and combined in the background.
So can someone help me in fixing the issue.
Convert all date format into string like .ToString("YYYY-MM-DD")
Format datepicker as dateFormat: "yyyy-mm-dd"
I am using angular bootstrap datepicker. Everythings works fine but when I select any date like 20-march-2015 it showing me 19-march-2015(one day less from selected day).
Here is my code in Plunker
This is a daylight saving issue.
Do you get the same issue with dates in February.
Looking at your example you can see the date is
OutPut: "2015-04-26T23:00:00.000Z"
For today :)
if I select 1st Jan, I get
OutPut: "2015-01-01T00:00:00.000Z"
Change your SPAN to
<span>OutPut: {{formData.dueDate | date : 'dd/MM/yyyy'}}</span>
And your good ( note the | date : 'dd/MM/yyyy' )
Actually you don't need datepicker. Delete datepicker and use type="date".
<input ng-model="formData.dueDate" type="date" id="dueDate" name="dueDate"
class="form-control" ng-click="data.isOpen = true">
Example
I have found an issue with validation of a manually typed date value that falls outside of the minDate or maxDate values when using the datepicker-popup.
This can be demonstrated with the datepicker popup on the angular ui site by following the steps below: http://angular-ui.github.io/bootstrap/#/datepicker
Ensure the min date option is turned on (min date should equal today)
Type in yesterdays date to the datepicker-popup
This shows a red border around the inline datepicker (as it is flagged as ng-invalid-date) however the input box for the datepicker-popup is still valid.
On further investigation it seems that the ng-invalid-date attribute has been set against the popup part of datepicker and not against the input box. This causes issues because firstly, the user cannot see that the element is invalid and secondly the popup does not have a name property so I am unable to check validity from the ng-form (e.g. myForm.myDate.$invalid
Does anyone know any way around this?
You can do an additional validation on ng-change for the text field and setValidity of that field to false to achieve what you want. Here is a plunker that demonstrates the idea.
http://plnkr.co/edit/N9Hk9QFIfj3IXfHoWwbt?p=preview
I added a little css styling to get the red border to show when the field is invalid. The validity test is very basic; you'd want to enhance it to allow the current day.
If you have the input set up like this, <input type="text" class="form-control" uib-datepicker-popup="{{format}}" ng-model="date" is-open="open" datepicker-options="datePickerDateOptions" close-text="Close" ng-change="change()" />
then in your controller you can check what $scope.date is in your $scope.change() function. If $scope.date is undefined then its not valid. If its null then its empty. Anything else is a valid date.
