uninvoke a jquery tools calendar
<pre><code>$(this).parent().find('input.query').dateinput();
</code></pre>

<p>when someone selects the "date" option from a select box, i attach dateinput() to the text box for them to enter a date.  but if they change their mind and select "text" from the select box, I'm not clear on how to turn off the dateinput() that I assigned...</p>
