Formatting a date in javascript
I know other possible formats in JavaScript Date object but I did not get on how to format the date to MM/dd/yyyy HH:mm:ss format. 
Please let me know if you come across such problem.

    [Addendum 12/2022]: Here's a library to format dates using Intl.DateTimeFormat.
Try something like this
var d = new Date,
    dformat = [d.getMonth()+1,
               d.getDate(),
               d.getFullYear()].join('/')+' '+
              [d.getHours(),
               d.getMinutes(),
               d.getSeconds()].join(':');
If you want leading zero's for values < 10, use this number extension
Number.prototype.padLeft = function(base,chr){
    var  len = (String(base || 10).length - String(this).length)+1;
    return len > 0? new Array(len).join(chr || '0')+this : this;
}
// usage
//=> 3..padLeft() => '03'
//=> 3..padLeft(100,'-') => '--3' 
Applied to the previous code:
var d = new Date,
    dformat = [(d.getMonth()+1).padLeft(),
               d.getDate().padLeft(),
               d.getFullYear()].join('/') +' ' +
              [d.getHours().padLeft(),
               d.getMinutes().padLeft(),
               d.getSeconds().padLeft()].join(':');
//=> dformat => '05/17/2012 10:52:21'
See this code in jsfiddle
[edit 2019] Using ES20xx, you can use a template literal and the new padStart string extension.
const dt = new Date();
const padL = (nr, len = 2, chr = `0`) => `${nr}`.padStart(2, chr);
console.log(`${
    padL(dt.getMonth()+1)}/${
    padL(dt.getDate())}/${
    dt.getFullYear()} ${
    padL(dt.getHours())}:${
    padL(dt.getMinutes())}:${
    padL(dt.getSeconds())}`
); 
    
    You can always format a date by extracting the parts and combine them using string functions in desired order:
var date = new Date();
var dateStr =
  ("00" + (date.getMonth() + 1)).slice(-2) + "/" +
  ("00" + date.getDate()).slice(-2) + "/" +
  date.getFullYear() + " " +
  ("00" + date.getHours()).slice(-2) + ":" +
  ("00" + date.getMinutes()).slice(-2) + ":" +
  ("00" + date.getSeconds()).slice(-2);
console.log(dateStr); 
    
    var d = new Date();
var curr_date = d.getDate();
var curr_month = d.getMonth();
var curr_year = d.getFullYear();
document.write(curr_date + "-" + curr_month + "-" + curr_year);
using this you can format date.
you can change the appearance in the way you want then

var d = new Date();
// calling the function
formatDate(d,4);
function formatDate(dateObj,format)
{
    var monthNames = [ "January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December" ];
    var curr_date = dateObj.getDate();
    var curr_month = dateObj.getMonth();
    curr_month = curr_month + 1;
    var curr_year = dateObj.getFullYear();
    var curr_min = dateObj.getMinutes();
    var curr_hr= dateObj.getHours();
    var curr_sc= dateObj.getSeconds();
    if(curr_month.toString().length == 1)
    curr_month = '0' + curr_month;      
    if(curr_date.toString().length == 1)
    curr_date = '0' + curr_date;
    if(curr_hr.toString().length == 1)
    curr_hr = '0' + curr_hr;
    if(curr_min.toString().length == 1)
    curr_min = '0' + curr_min;
    if(format ==1)//dd-mm-yyyy
    {
        return curr_date + "-"+curr_month+ "-"+curr_year;       
    }
    else if(format ==2)//yyyy-mm-dd
    {
        return curr_year + "-"+curr_month+ "-"+curr_date;       
    }
    else if(format ==3)//dd/mm/yyyy
    {
        return curr_date + "/"+curr_month+ "/"+curr_year;       
    }
    else if(format ==4)// MM/dd/yyyy HH:mm:ss
    {
        return curr_month+"/"+curr_date +"/"+curr_year+ " "+curr_hr+":"+curr_min+":"+curr_sc;       
    }
}
