Why is my jQuery keydown feature only working on the first input element
<p>I've built a small jQuery script that adds a class to witch ever input field I'm writing in. However it only works on all input fields after something is written in the first input field, see <a href="http://dev.resihop.nu/" rel="nofollow">dev.resihop.nu</a> for example.</p>

<p>The code:</p>

<pre><code>$('.field').keydown(function () {
  if ($('.field').val() !== 'Ort, gata eller kommun') {  
    $(this).addClass("focus");
  };
});
</code></pre>
