Formatting Date from JSON to Datepicker field

Question

After studying I've learned JSON has no standard date literal, which surprised me. I've checked my code and database and it looks like the problem I have is the JSON portion and getting that to appear as MM/DD/YYYY in the datepicker field.

The start value of data.BoardStart is: "/Date(1454519004200)/"

So I'm parsing it using: var BoardStart = new Date(parseInt(data.BoardStart.replace("/Date(", "").replace(")/", ""), 10));

This outputs it to a something like wed feb 03 2016 10:03:24 gmt-0700 (mountain standard time)

This results in an error: BoardStart.format("MM-DD-YYYY");

Any suggestions would be appreciated

@DanielA.White No, the OP already figured out how to make a `Date` object — Ruan Mendes, May 22 '15 at 18:10

Your error is because there is no format method on a Date object. See https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date

You have to write your own formatting code or use a library like http://momentjs.com/

var jsonDate = "/Date(1454519004200)/"

var BoardStart = new Date(parseInt(jsonDate.replace("/Date(", "").replace(")/", ""), 10));

console.log(moment(BoardStart).format('MM-DD-YYYY'))
