Autofill Form Fields (JavaScript)

INTRO

I am a developer and one of my main issue is fill all form fields of a form module. What a boring task!

REQUIREMENTS

jQuery.

INSTALL

Create a new bookmarklet into your browser bookmark toolbar.
Unwrap all the JavaScript code in a text editor (ie Notepad++).
Paste all the JavaScript code.
Use the bookmarklet into your page.

SCRIPT / SOURCE CODE

javascript:Filler();
function Filler() {
	function getRandomString(len) {
		/* Script by http://www.mediacollege.com/internet/javascript/number/random.html */
		var chars = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXTZabcdefghiklmnopqrstuvwxyz";
		var randomstring = '';
		for (var i=0; i<len; i++) {
			var rnum = Math.floor(Math.random() * chars.length);
			randomstring += chars.substring(rnum,rnum+1);
		}
		return randomstring;
	}
	$('form').each(function(i) {
		$('input[type=text]').each( function(i) {
			$(this).val( getRandomString(8) );
		} );
		$('input[type=checkbox]').each( function(i) {
			$(this).attr('checked', 'true');
		} );
	});
}
