[jQuery] Handle cross-site JSON in Form Plugin malsup


hi,
I have a question about handle cross-domain JSON data in Form Plugin.
I use the sample of JSON at
http://www.malsup.com/jquery/form/#code-samples
When I place the client Form and Server side code in different domain,
it just show the raw JSON data.
<form id="jsonForm" action="http:www.my-site.com/json-echo.php"
method="post">
Message: <input type="text" name="message" value="Hello JSON" />
<input type="submit" value="Echo as JSON" />
</form>
How can I handle the JSON data when it respond from different domain?
Thanks
Joel Sun
