Split string to get hours

var date = '28/05/2011 12:05';
var elem = date.split('');
hours = elem[0]开发者_StackOverflow;

I have the above date format, please tell me how to split this, so that I can obtain 12 (hours) from this string?

var date = '28/05/2011 12:05';
var hrs = date.split(' ')[1].split(':')[0];

You can use a single call to split each component using a regular expression:

var date = '28/05/2011 12:05';
var elem = date.split(/[/ :]/);
alert(elem[3]); //-> 12

Working example: http://jsfiddle.net/gZ9c7/

A RegEx solution:

var myRe = /([0-9]+):[0-9]+$/i;
var myArray = myRe.exec("28/05/2011 12:05");

alert(myArray[1]); // 12

Some additional info:

• Working code sample here.
• About RegEx in JS.

As long as it's a consistent format:

var hours = date.split(' ')[1].split(':')[0]

is pretty easy.

when working with Dates it's better to use dedicated date/time functions:

var date = '28/05/2011 12:05';
var ms = Date.parse(date)
alert(new Date(ms).getHours())
