Question

Given a string like:

Sun Feb 06 2011 12:49:55 GMT-0800 (PST)

How can you convert that to:

Feb 6

And / Or

Sun Jan 26 2011 12:49:55 GMT-0800 (PST)
to: Jan 26

Any ideas?

Answer 1

There aren’t any built-in formatting functions to use here, you just have to use the Date methods to build the string:

var months = [
    'Jan', 'Feb', 'Mar', 'Apr',
    'May', 'Jun', 'Jul', 'Aug',
    'Sept', 'Oct', 'Nov', 'Dec'
];

var d = new Date();
// Or,
var d = new Date('Sun Feb 06 2011 12:49:55 GMT-0800 (PST)');

alert(months[d.getMonth()] + ' ' + d.getDate());

Or, if that string will always stay in that format, you can simply extract the relevant parts without converting it to a date object first:

var str = 'Sun Feb 06 2011 12:49:55 GMT-0800 (PST)';
var components = str.split(' ').slice(1, 3);
components[1].replace(/^0/, '');
alert(components.join(' '));
