javascript - Two jQuery versions on the same page

Question

Is it possible to have 2 different jQuery versions in the same document, and have them to not collide with each other?

For example if I create a bookmarklet and want to base the code on jQuery. This bookmarklet is injected on some page that uses another version of jQuery then my code would overwrite the version used on the page.

Is it possible to avoid that? Or are there some other libraries that provides this functionality Or maybe I should rethink the whole thing.

Thanks for answers and pointers,

bob

jQuery comes with a way to avoid collisions. After you load the first version, you can assign it to a different variable.

var $j = jQuery.noConflict();

And then load your second jQuery version. The first one you load can be accessed with $j(...) while the second one can be accessed with $(...).

Alternatively, somebody made a little helper in an attempt to make it easier to switch between different versions.
