Remove all White Space using JavaScript

Here’s how to remove all whitespaces (leading, trailing and in between) in a textbox using JavaScript

<html xmlns="" >
<title>Remove Whitespaces using JavaScript by</title>
<script type="text/javascript">
function removeWhitespaces() {
var txtbox = document.getElementById('txtOne');
txtbox.value = txtbox.value.replace(/\s/g, "");
<input id="txtOne" type="text" /><br />
<input id="btnRemoveWs" type="submit"
value="Remove Whitespaces" onclick="removeWhitespaces()" />

As you can see, we are using a simple regular expression \s/g which removes all whitespaces. The "g" stands for "global" which replaces all white space matches (front, trailing and in between).
