Disable <a class button if input fields empty

[qwikad.com]

I know it's easy to do using <button> or <input type="submit" but how would you keep this button disabled unless both input fields are filled?

<input id="one" type="text">
<input id="two" type="text">
 <a href="#" class="button">OK</a>

Disable and href? Maybe you could preventDefault / return false; or remove the href attribute with removeAttribute('href') ?

Or how about hiding the link with style.display='none'; and when the input is filled, show it with style.display='block';

Thank you. I got some help over on stackoverflow. Similar to what you suggested.

$('#one, #two').blur(function() {
   if($('#one').val() !== "" && $('#two').val() !== "") {
       $('.button').removeAttr('href');
   } else {
      $('.button').attr('href','#');
   }
});

And then you just do the button as <a class="button">OK</a>
