How to remove spaces from a string using JavaScript?

How to remove spaces in a string? For instance:

Input:

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

Output:

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

  • 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.
