Is it possible to use Jquery in DNN 4.9.0? I fidured that it should but when I add a <script> tag to link to the jquery.js file the page loads up but then funky things happen to the menus, the control panel and the admin pages. Including the "update" link stops working in the admin page which is a real pain in the ass b/c then I can't take out my reference to the script without going into the database.

I know that jQuery is not officially supported in 4.9.0 but I wanted to make use of it in one small Text/HTML module and can't b/c of all of the trouble it causes. Just looking to see if there's an easy solution with upgrading.

Yeah, the only way I've ever been able to get it to work was using jQuery.noConflict; some plugins don't play well with that because they weren't designed to work in no conflict mode, but overall I've had great success with it.  I just slapped together a really quick "No Right Click" module last night for use on a client's site, in fact, which uses jQuery.  You can see the module in action on his site (no content available yet because he hasn't given me the info) but right-click is disabled on images: http://www.muleequipped.com (I haven't tested in all browsers but the plugin I'm using says it doesn't work correctly in Opera).

Sorry, one thing I left out of my reply.  You *could* use a script injector (GumboSoft has one) to link the jQuery library and then put in some of your own script that calls the jQuery.noConflict(); and then your own script to do whatever you wanted to do on it.

I'd assume your own script would be something like this:

jQuery.noConflict();
jQuery(document).ready(function() {
	// put your code here
});
