Question

Given input like "Tue Aug 30 2011 11:47:14 GMT-0300", I would like output like "MMM DD YYYY hh:mm".

What is an easy way to do it in JavaScript?

Answer 1

Via JS, you can try converting it to a date object and then extract the relevant bits and use them:

var d = new Date ("Tue Aug 30 2011 11:47:14 GMT-0300")
d.getMonth(); // gives you 7, so you need to translate that

To ease it off, you can use a library like date-js

Via regex:

/[a-zA-Z]{3} ([a-zA-Z]{3} \d{2} \d{4} \d{2}:\d{2})/ should do the trick.

var r = "Tue Aug 30 2011 11:47:14 GMT-0300".match(/^[a-zA-Z]{3} ([a-zA-Z]{3} \d{2} \d{4} \d{2}:\d{2})/);
alert(r[1]);   // gives you Aug 30 2011 11:47
