Javascript Date Parsing issue in IE

Question

I have a string in JavaScript 2015-07-22 00:00:00.0. I need this to be converted to mm/dd/yy format

I tried parsing with var d = new Date(from_date);, which works in Chrome,but not in IE or Firefox

Then I tried with regex pattern replace, but it still works only in Chrome but not in IE or Firefox

var st = '2015-07-22 00:00:00.0'
var pattern = '\d{4})\-(\d{2})\-(\d{2})/'
var dt = new Date(st.replace(pattern, '$2-$3-$1'));
var output = dt.getMonth() + 1 + '/' + dt.getDate() + '/' + dt.getFullYear();
alert(output) 

JSFiddle

Kindly throw some light.

Answer 1

If the date is always in that format, you can substring it out and use the standard date format to get it working.

var r = "2015-07-22 00:00:00.0"
var date = new Date(r.substring(0, 4),   //year
                    r.substring(5, 7),   //month
                    r.substring(8, 10),   //day
                    r.substring(11, 13), //hour
                    r.substring(14, 16), //min
                    r.substring(17, 19), //sec
                    r.substring(20));    //mili

Whenever you do anything with date and or time in Javascript, I would advice you to use momentJS

In your case you should do something like this to parse the string:

var x = moment(st, "YYYY-MM-DD");

Then for output:

console.log( x.format("MM/DD/YYYY") );

This should work fine for you.

var date = new Date('2015-07-22 00:00:00.0'.replace(/ /g, 'T')),
  monthDigits = [ '01', '02', '03', '04', '05', '06', '07', '08', '09', '10', '11', '12' ];

console.log(monthDigits[date.getMonth()] + '/' + date.getDate() + '/' + date.getFullYear());
