jQuery: Reset input to default value when document ready

Using jQuery, how can I reset an input to its default value?  in Firefox, this code makes all inputs blank when the page is refreshed.

<html xmlns="http://www.w3.org/1999/xhtml">
<head>

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7/jquery.min.js"></script>
<script type="text/javascript">

history.navigationMode = 'compatible';
$('*').unbind();
$(window).unload(function () {
 scroll(0, 0);
 $('*').unbind();
 $('input[type=text], select, textarea').val('');
});

$(document).ready(function() {

});

</script>
</head>
<body>
 <div>
  <input type="text" size="3" maxlength="2" value="1" />
  <input type="text" size="3" maxlength="2" value="2" />
  <input type="text" size="3" maxlength="2" value="3" />
 </div>
</body>
</html>

onunload is unreliable
Why would you want to clear the values before the page is refreshed?

GaryC123, I am using onunload to demonstrate the problem.  It is one of the ways that form values can get changed.  

leakim971, your code makes the inputs always blank.  They should be reset to the values "1", "2" and "3" respectively every time you refresh the page.

Don't make sense
You're making a problem out of a situation that makes no sense.
If the page is refreshed what does it matter what is in the textboxes, the elements cease to exist.
FF has aggressive caching and will autofill inputs etc with previous values. To stop this you can use autocomplete="off".  If you don't want to do it manually you can use jquery to set the attribute at load time.
