I have a page with an iframe in it. my iframe page is iframe.php and my main page is main.php when i load iframe.php directly my jquery code executes fine, but when I load main.php (which contains iframe.php as an iframe) I get an error "$ is not defined".

could this be because both main.php and iframe.php use

<script type="text/javascript" src="http://code.jquery.com/jquery-latest.pack.js"></script>

if so how can I use jquery in the iframe page without including this line?

jquery iframe
