javascript string remove white spaces and hyphens

Question

I would like to remove white spaces and hyphens from a given string.

 var string = "john-doe alejnadro";
 var new_string = string.replace(/-\s/g,"")

Doesn't work, but this next line works for me:

var new_string = string.replace(/-/g,"").replace(/ /g, "")

How do I do it in one go ?

var new_string = string.replace(/-|\s/g,"");

a|b will match either a or b, so this matches both hyphens and whitespace.

Example:

> "hyphen-containing string".replace(/-|\s/g,"")
'hyphencontainingstring'

You have to use:

 var new_string = string.replace(/[-\s]/g,"")

/-\s/ means hyphen followed by white space.

Use This for Hyphens

var str="185-51-671";
var newStr = str.replace(/-/g, "");

White Space

var Actuly = newStr.trim();

.trim() will only remove whitespace at the beginning or end of a string
