Java date format to JavaScript date format

Question

I would like to be able to convert a Java date format string, e.g. dd/MM/yyyy (07/06/2009) to a JavaScript date format string, e.g. dd/mm/yy (07/06/2009).

Answer 1

This JavaScript library should be able to help you.

http://plugins.jquery.com/project/fIsForFormat

(I don't know why they have it as a jQuery Plugin, because it works standalone.)

You'd simply split the original formatted date into its individual elements and then create a new Date Object with those elements. Then, use this library's "Date.f()" method to output it into any format you could want.

For example:

var dateOld = "11/27/2010",
    dateArr = date1.split("/"),
    dateObj = new Date(dateArr[2], dateArr[0], dateArr[1]),
    dateNew = dateObj.f("MMM d, yyyy");

document.write("Old Format: " + dateOld + "<br/>New Format: " + dateNew);

Answer 2

You could use my plugin jquery-dateFormat.

// Text
$.format.date("2009-12-18 10:54:50.546", "dd/MM/yyyy");
// HTML Object
$.format.date($("#spanDate").text(), "dd/MM/yyyy");
// Scriptlet
$.format.date("<%=java.util.Date().toString()%>", "dd/MM/yyyy");
// JSON
var obj = ajaxRequest();
$.format.date(obj.date, "dd/MM/yyyy");

Check out moment.js! It's "A lightweight javascript date library for parsing, manipulating, and formatting dates". It is a really powerful little library.

Here's an example...

var today = moment(new Date());
today.format("MMMM D, YYYY h:m A");        // outputs "April 11, 2012 2:32 PM"

// in one line...
moment().format("MMMM D, YYYY h:m A");     // outputs "April 11, 2012 2:32 PM"

Here's another example...

var a = moment([2012, 2, 12, 15, 25, 50, 125]);
a.format("ffffdd, MMMM Do YYYY, h:mm:ss a"); // "Monday, March 12th 2012, 3:25:50 pm"
a.format("ffffd, hA");                       // "Mon, 3PM"
a.format("D/M/YYYY");                      // "12/3/2012"

Also, its worth mentioning to checkout date.js. I think the two libraries complement each other.

Answer 4

The javascript code in this page implements some date functions and they "use the same format strings as the java.text.SimpleDateFormat class, with a few minor exceptions". It is not the very same as you want but it can be a good start point.

Answer 5

A similar topic has been answered here: Converting dates in JavaScript

I personally have found this to be a rather large pain and took the author's suggestion and used a library. As noted, jQuery datepicker has one that is a viable solution if you can afford the overhead of download for your application or already using it.

Answer 6

If you are using java, take a look at the Simple Date Format class.
