Remove ALL white spaces from text

$("#topNav" + $("#breadCrumb2nd").text().replace(" ", "")).add开发者_运维问答Class("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.

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,'')

---

.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, "")

---

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:

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

---

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

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

---

let str = 'a big fat hen clock mouse '
console.log(str.split(' ').join(''))
// abigfathenclockmouse

---

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

This will solve the problem.

Happy Coding !!!

---

simple solution could be : just replace white space ask key value

val = val.replace(' ', '')

---

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

for example:

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

---

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)

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

Example:

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

function RemoveAllSpaces(ToRemove)
{
    let str = new String(ToRemove);
    while(str.includes(" "))
    {
        str = str.replace(" ", "");
    }
    return str;
}
