i have a service i’m building, which will be included as JS on client web pages. optimally, i want to build the service using jquery.
the case may arise, where the page already has JQ included.
how do i avoid including JQ twice in the page? how do i make sure i still have the desired JQ functionality, even if the page has already included an older version of JQ?
is the only solution simply abandoning JQ and going with hand-coded script?
Check for the existence of
jQueryand match the version you need againstjQuery.fn.jquery.
