Yesterday, after seeing this thread, I started work on a "jQuery Lint"
script. You can see it here: http://github.com/jamespadolsey/jQuery-Lint
It does a few basic checks - argument signatures being the main one.
It also tries to combat lack-of-caching with selections, and it will
warn you when your selection returns nothing. It'll also suggest that
you use attr({...})/css({...} instead of css().css().css().css() ...
I've added a simple API via which you can add special checks. For
example:
jQuery.LINT.special[1].jQuery = function(selector, context) {
if (selector === '*') {return "Don't use the universal
selector!"; }
// Everything is fine... don't return anything (or return true)
};
So, potentially, one of you could create a bunch of these "special
checks" and release them all as a separate script which can be slotted
in with Lint.
It's been made to work with Firebug, but you can quite easily slot in
your own console mechanism via jQuery.LINT.console.
Like I said, this was started yesterday, so it's still got a few
kinks...
