how to perform events when a checkbox is checked/unchecked in jquery
<p>I have the following jquery code which works fine. </p>

<pre><code>$('#onlyTwo').click(function() {
                $("#textarea3").attr("disabled", true);
                $("#textarea4").attr("disabled", true);
                $("#radio3").attr("disabled", true);
                $("#radio4").attr("disabled", true);
                return true;
            });
</code></pre>

<p>This is making some fields disabled when 'onlyTwo' checkbox is clicked.  How can i make these fields enabed again when 'onlyTwo' checkbox is unchecked...</p>

<p>basically i want to know how to find out whether a checkbox is checked or not</p>
