I am currently working on a sharepoint site that has an old version of jquery ui (1.5.3) included in the head section of the master page.
I can’t touch any of the master page code as I don’t have access to it and I need to use the latested version of jquery ui in order for jCoverflip plugin to work.
Use jQuery.noConflict
It allows youto make multiple versions of jQuery coexist on the same page.
