how to display a date as 2/25/2007 format in javascript, if i have date object
Check out moment.js! It's a really powerful little library for working with Dates in JavaScript.
Using moment.js...
var today = moment(new Date());
today.format("M/D/YYYY"); // "4/11/2012"
today.format("MMMM D, YYYY h:m A"); // outputs "April 11, 2012 12:44 AM"
// in one line...
moment().format("M/D/YYY"); // "4/11/2012"
moment().format("MMMM D, YYYY h:m A"); // outputs "April 11, 2012 12:49 AM"
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"
Also, its worth mentioning to checkout date.js. I think the two libraries complement each other.
