How to create a date object from string in javascript [duplicate]

Having this string 30/11/2011. I want to convert it to date object.

Do I need to use :

Date d = new Date(2011,11,30);   /* months 1..12? */

or

Date d = new Date(2011,10,30);   /* months 0..11? */

?

var d = new Date(2011,10,30);

as months are indexed from 0 in js.

You definitely want to use the second expression since months in JS are enumerated from 0.

Also you may use Date.parse method, but it uses different date format:

var timestamp = Date.parse("11/30/2011");
var dateObject = new Date(timestamp);

The syntax is as follows:

new Date(year, month [, day, hour, minute, second, millisecond ])

so

Date d = new Date(2011,10,30);

is correct; day, hour, minute, second, millisecond are optional.

There are multiple methods of creating date as discussed above. I would not repeat same stuff. Here is small method to convert String to Date in Java Script if that is what you are looking for,

function compareDate(str1){
// str1 format should be dd/mm/yyyy. Separator can be anything e.g. / or -. It wont effect
var dt1   = parseInt(str1.substring(0,2));
var mon1  = parseInt(str1.substring(3,5));
var yr1   = parseInt(str1.substring(6,10));
var date1 = new Date(yr1, mon1-1, dt1);
return date1;
}

Very simple:

var dt=new Date("2011/11/30");

Date should be in ISO format yyyy/MM/dd.
