Replace all whitespace characters

Question

I want to replace all occurrences of white space characters (space, tab, newline) in JavaScript.
How to do so?

I tried:

str.replace(/ /gi, \"X\         


        

Answer 1

If you use

str.replace(/\s/g, "");

it replaces all whitespaces. For example:

var str = "hello my world";
str.replace(/\s/g, "") //the result will be "hellomyworld"
