Accessing a JSON value within the AngularJS controller for the purpose of making edits

Seeking assistance here, as I work with a JSON file to generate a timeline using AngularJS. While I've successfully utilized the ng-repeat loop in HTML binding to display dates, I now need to modify the date format – specifically, changing "2013-01-01" to "December 31, 2012."

I am currently grappling with how to retrieve the date value within the controller so that I can incorporate it into a function for adjusting the date by adding one more day to its value.

Your help is greatly appreciated! I hope my request is clear enough.

Answer №1

The localization of dates in Javascript happens automatically. In Angular, the date filter requires a timezone to be specified, and if none is provided, it defaults to UTC. The problem arises when a timezone-less string (assumed to be UTC) is localized, resulting in a date that is not exactly 2013-01-01 but rather offset by the number of hours in your timezone. For example, in Pacific Standard Time, this would be -8 hours, making the date appear to be a day earlier.

Ideally, data coming from a server should include timezone information for accurate processing - this is considered a best practice. If no timezone is available, assuming UTC is a reasonable approach as some standard reference point is necessary.

For demonstration purposes, you can refer to this Plunker which showcases various scenarios related to date localization: http://plnkr.co/edit/Jhwnkj?p=preview

Answer №2

Implement the Angular date Filter directly in your view without altering any values in the controller. Check out this helpful example: http://plnkr.co/edit/iqIpW5uADTRVFycDxdBa
