jQuery readonly attribute problems
<p>I have this</p>

<pre><code>&lt;input type="text" id="tbox" name="tbox" readonly="readonly" /&gt;
</code></pre>

<p>I have a button on which I do this</p>

<pre><code>$('#tbox').removeAttr('readonly');
</code></pre>

<p>I've also tried doing this</p>

<pre><code>$('#tbox').attr('readonly', false);
</code></pre>

<p>.. but none work..</p>
