Remove ALL white spaces from text

$("#topNav" + $("#breadCrumb2nd").text().replace(" ", "")).addClass("current");

This is a snippet from my code. I want to add a class to an ID after getting another ID's text property. The problem with this, is the ID holding the text I need, contains gaps between the letters.

I would like the white spaces removed. I have tried TRIM()and REPLACE() but this only partially works. The REPLACE() only removes the 1st space.

Regex for remove white space

\s+


var str = "Visit Microsoft!";
var res = str.replace(/\s+/g, "");
console.log(res);

or

[ ]+


var str = "Visit Microsoft!";
var res = str.replace(/[ ]+/g, "");
console.log(res);

Remove all white space at begin of string

^[ ]+


var str = "    Visit Microsoft!";
var res = str.replace(/^[ ]+/g, "");
console.log(res);

remove all white space at end of string

[ ]+$


var str = "Visit Microsoft!      ";
var res = str.replace(/[ ]+$/g, "");
console.log(res);

var myString="fg gg";
console.log(myString.replaceAll(' ',''));

** 100% working

use replace(/ +/g,'_'): 

let text = "I     love you"
text = text.replace(/ +/g, '_') // replace with underscore ('_')

console.log(text) // I_love_you

Well, we can also use that [^A-Za-z] with g flag for removing all the spaces in text. Where negated or complemente or ^. Show to the every character or range of character which is inside the brackets. And the about g is indicating that we search globally.

let str = "D  S@ D2m4a   r k  23";

// We are only allowed the character in that range A-Za-z

str = str.replace(/[^A-Za-z]/g,"");  // output:- DSDmark

console.log(str)

I don't understand why we need to use regex here when we can simply use replaceAll

let result = string.replaceAll(' ', '')

result will store string without spaces

Use string.replace(/\s/g,'')

This will solve the problem.

Happy Coding !!!

You have to tell replace() to repeat the regex:

.replace(/ /g,'')

The g character makes it a "global" match, meaning it repeats the search through the entire string. Read about this, and other RegEx modifiers available in JavaScript here.

If you want to match all whitespace, and not just the literal space character, use \s instead:

.replace(/\s/g,'')

You can also use .replaceAll if you're using a sufficiently recent version of JavaScript, but there's not really any reason to for your specific use case, since catching all whitespace requires a regex, and when using a regex with .replaceAll, it must be global, so you just end up with extra typing:

.replaceAll(/\s/g,'')

Now you can use "replaceAll":

console.log(' a b    c d e   f g   '.replaceAll(' ',''));

will print:

abcdefg

But not working in every possible browser:

Using .replace(/\s+/g,'') works fine;

Example:

this.slug = removeAccent(this.slug).replace(/\s+/g,'');

Use replace(/\s+/g,''),

for example:

const stripped = '    My String With A    Lot Whitespace  '.replace(/\s+/g, '')// 'MyStringWithALotWhitespace'

Using String.prototype.replace with regex, as mentioned in the other answers, is certainly the best solution.

But, just for fun, you can also remove all whitespaces from a text by using String.prototype.split and String.prototype.join:

const text = ' a b    c d e   f g   ';
const newText = text.split(/\s/).join('');

console.log(newText); // prints abcdefg

.replace(/\s+/, "")

Will replace the first whitespace only, this includes spaces, tabs and new lines.

To replace all whitespace in the string you need to use global mode

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