jQuery Remove all Spaces in String

In this tutorial we will learn how to Remove all spaces in String with jQuery. We can use replace() method with RegExp g Modifier to look for all spaces and then they can be removed.

replace() method

replace() method searches for the defined value or regular expression and then replaces it with other defined value.

replace() method doesn't change the original string.

RegExp g Modifier

RegExp g Modifier is used for a global search which means it looks for all matches instead of first or last match.

This will find all spaces present in a string, then they are removed.

HTML Code

HTML Code is given below, in this code input tag is used to take string as an input and new string with all spaces removed are displayed using the paragraph tag.

Button tag is used to execute the code on click event.

<!DOCTYPE html>
<html>
<head>
<title>jQuery Remove all Spaces in String</title>
<script src="https://code.jquery.com/jquery-3.5.1.min.js"></script>
</head>

<input id="string" type="text">
<p id="output"></p>    
<button id="btn">Remove Spaces</button>
    
<script src="script.js"></script>    
</body>
</html>

  $('#btn').click(function(){
    var string = $('#string').val();
    var newString = string.replace(/ /g , "");
