How to remove spaces from a string using JavaScript?

Question

How to remove spaces in a string? For instance:

Input:

'/var/www/site/Brand new document.docx' 

Output:

'/var/www/site/Brandnewdocument.docx' 

Answer 1

This?

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

Example

var str = '/var/www/site/Brand new document.docx';    document.write( str.replace(/\s/g, '') );

---

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.
