jQuery purpose on frontend

I have a scenario where the version of jQuery packaged with 2.0 (1.11.2) is breaking something in a theme of mine that jQuery included in 1.7.8 (1.8.3) did not.
  • What does jQuery do on the front end?
  • Can we specifically tell s9y to NOT load jQuery, so a theme can load a specific version of jQuery, different from what s9y would use on the front end?
  • I know I can load an older version of jQuery since s9y is using no-conflict, and this actually solves my problem. Is there a huge down side to this?

Various plugins (lightbox comes to mind) and themes (2k11, for instance) use it in their JS. jQuery itself does not do anything since it's a library.

Yes. Set $serendipity['capabilities']['jquery'] = false; in your config.inc.php, bundle your own jQuery version (but set noConflict mode for that as well for plugins to work properly).

Yes. You would be loading 2 versions of the same library which means an extra http request, about 95KB loaded unneccessarily and a very bad practice. Also, you're gonna get laughed at. :wink:

The best solution would really be to fix whatever is not working with jQuery 1.11.2 any longer. This is most likely related to something in the theme's JS (or maybe a jQuery plugin used in the theme) that was deprecated in jQuery between 1.8.3 and 1.11.2. Does it give you any error message in the browser's JS console?

Yeah, I know. It is not the theme's own JS, it is an included jQuery plugin that I have to update.... and really didn't want to update!! :|

Have we ever used < jQuery 1.7 on the front end? 1.7.8 used jQuery 1.8.3.

Yes. The first jQuery ever to be bundled with the s9y core was 1.4.4.
