This?

str = str.replace(/\s/g, '');

Demo.

Update: Based on this question, this:

str = str.replace(/\s+/g, '');

is a better solution. It produces the same result, but it does it faster.

The Regex

\s is the regex for "whitespace", and g is the "global" flag, meaning match ALL \s (whitespaces).

A great explanation for + can be found here.

As a side note, you could replace the content between the single quotes to anything you want, so you can replace whitespace with any other string.

just beat me... –  Gaurav May 11 '11 at 11:06
    
@Gaurav I've looked up similar answers on SO, and I see .replace(/\s+/g, '') more often. Is there a difference between that and my answer? –  Šime Vidas May 11 '11 at 11:17
    
in this case there is no difference. But + is used for finding with atleast one occurrence. –  Gaurav May 11 '11 at 11:23

var a = "/var/www/site/Brand new document.docx";
alert(a.split(' ').join(''));
alert(a.replace( /\s/g, ""));

Two ways of doing this!
