Splitting date in Javascript

Question

var date = "1st December,2016"

How can I split this string to get date,month and year? I am doing date.split(" ",1) then I am getting output as "1st". Now how to get December and 2016?

If you could make sure that your string always has that format, the simplest way is to use 2 split command:

var date = "1st December,2016";

var arr1 = date.split(' ');
var arr2 = arr1[1].split(',');

console.log('date: ', arr1[0]);
console.log('month: ', arr2[0]);
console.log('year: ', arr2[1]);

Update: I just realize split could be used with Regex, so you could use this code too:

var date = '1st December,2016';
var arr = date.split(/ |,/);

console.log('date: ', arr[0]);
console.log('month: ', arr[1]);
console.log('year: ', arr[2]);

Use Regular Expression for that,

 function ShowDateParts()
{   

 var regex =/\s|,/g;
fullDate = "1st December,2016";
var dateParts =fullDate.split(/[\s|,]/g);
alert("date : "+ dateParts[0] + " Month : " +dateParts[01] + " Year : " + dateParts[02]);
    
}

Why is that array index `01` and not `1`? – Rahul Desai Jan 18 '17 at 05:59
`[01]` will fail in strict mode, since it will be interpreted as an illegal octal literal. – Jan 18 '17 at 06:00

You don't need the alternation in character set `/[\s|,]/`, just `/[\s,]/`. – SLePort Jan 18 '17 at 06:08

I would create a date object out of my string value and use is to get all values.

Example Snippet:

var date = "1st December,2016";
//reftor to valid date
var validDate = date.replace(/(st)/, '');
//create date object
var dateObj = new Date(validDate);
//get any value you need
console.log(dateObj.getDate());
console.log(dateObj.getMonth());

Update:

Snippet to get intended output: (get month as string)

var monthNames = ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"];

var date = "1st December,2016";
//reftor to valid date
var validDate = date.replace(/(st)/, '');
//create date object
var dateObj = new Date(validDate);
//get any value you need
console.log(dateObj.getDate());
console.log(monthNames[dateObj.getMonth()]);
console.log(dateObj.getFullYear());

`getMonth` returns a zero-indexed int rather than the full text representation that they're after, so you would have to extend your code to do a lookup for that as well. – Marty Jan 18 '17 at 06:01
sure will extend snippet now. – Ajay Narain Mathur Jan 18 '17 at 06:03
You really should just parse the string to standard Date arguments and pass those, i.e. convert the month to a number then use `new Date(year, month-1, date)`. Parsing a string to create another string that is then parsed by the Date constructor is not recommended. But a Date is not required at all, the OP just wants the parts of the string. – RobG Jan 18 '17 at 06:36

Instead of

date.split(" ",1)

Just use

var dateparts = date.split(" ");

And then access each part as an array element.

var day=dateparts [0]; var month=dateparts [1].slice(0, -1); var year=dateparts [2];

But this will not split on the comma. – Jan 18 '17 at 06:01

var date = "1st December,2016";

var dataArray = date.split(/[ ,]/);

console.log('Day:' + dataArray[0]);
console.log('Month:' + dataArray[1]);
console.log('Year:' + dataArray[2]);
