How To: Limit Input Box Characters To Defined Count Using jQuery

Earlier today working on a project , I found one trick which I would like to share. Here is a small code that limit a input box for defined number of characters.

Please take a look on following example:

HTML

.

Jquery snippet

Assuming we have to limit characters to 20.

$(document).ready(function(){	
	$('#myInput').keyup( function() {
		var $this = $(this);
		if($this.val().length > 20)
			$this.val($this.val().substr(0, 20));			
	});
     });

.
