Handle JSON dates returned by ASP.NET AJAX

Updated on September 18, 2015     Kisan Patel

Problem:

When working with ASP.NET Web API or any other web service, you have to work with JSON data that is returned for Date data types and you have getting a string back that looks like this:

\/Date(1442255400000)\/

Solution:

var date = new Date(parseInt("\/Date(1442255400000)\/".substr(6)));

The substr function takes out the “/Date(” part, and the parseInt function gets the integer and ignores the “)/” at the end. The resulting number is passed into the Date constructor.
