$('input').val('') sets the values to "undefined" (when placeholder isn't natively supported, e.g. IE), even if .placeholder() is never invoked.

Test case:

<!DOCTYPE html>
<html>
  <head>
    <script type="text/javascript" src="http://code.jquery.com/jquery-1.7.1.min.js"></script>
    <script type="text/javascript" src="jquery.placeholder.js"></script>
    <script type="text/javascript">
$(function(){
  $('form').submit(function(event){
    event.preventDefault();
    $('input').val('');
  });
});
    </script>
  </head>
  <body>
<form>
  Text: <input type="text" name="txt"></input><br />
  Email: <input type="email" name="eml"></input><br />
  Password: <input type="password" name="pwd"></input><br />
  <input type="submit" name="sbmt" value="test" />
</form>
  </body>
</html>
</pre>

A workaround is to add placeholder attributes to the fields (such as placeholder="").
