Use the jQuery $.trim() function
You can use the jQuery $.trim() function to remove all the spaces (including non-breaking spaces), newlines, and tabs from the beginning and end of the specified string.
However, the whitespaces in the middle of the string are preserved. The following example will show you how to remove leading and trailing whitespaces from a string of text.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Remove White Space from Strings</title>
<script src="https://code.jquery.com/jquery-1.12.4.min.js"></script>
<script>
$(document).ready(function(){
var myStr = $(".original").text();
var trimStr = $.trim(myStr);
$(".trimmed").html(trimStr);
});
</script>
</head>
<body>
<h3>Original String</h3>
<pre class="original"> Paragraph of text with multiple white spaces before and after. </pre>
<br>
<h3>Trimmed String</h3>
<pre class="trimmed"></pre>
</body>
</html>
