JQuery ignore disabled radio buttons
<p>I have the following code that is called on submit, which checks that each Radio button is checked.</p>

<pre><code>$("input:radio").each(function() {
    var val = $('input:radio[id=' + this.id + ']:checked').val();
</code></pre>

<p>How can I modify this so that it excludes disabled values? (i.e. If the checkbox is disabled then ignore it)</p>

<p>Thanks</p>
