I am trying replace carriage return (\r) and newline (\n) and more than one spaces (' ' ) with single space.

I used \W+ which helped to achieve this but, it's replacing special characters also with space. I want to change this only replace above characters.

Please help me with proper regular expression with replace method in javascript.

• Is it \r AND \n AND more than one space, or \r OR \n OR more than one space, because your question asks for the first but anubhava has provided the regex for the second. – Andy Commented Jan 29, 2015 at 10:42

This will work: /\n|\s{2,}/g

var res = str.replace(/\n|\s{2,}/g, " ");

You can test it here: https://regex101.com/r/pQ8zU1/1

\s match any white space character [\r\n\t\f ]

You should use \s{2,} for this.It is made for this task.

This simple one should suit your needs: /[\r\n ]{2,}/g. Replace by a space.
