JavaScript Works in Development, Not in Production (Heroku)

Question

So I just pushed an app to Heroku, and JavaScript and jQuery are not working for me.

Have looked at a bunch of solutions for this but none seem to be work.

I have precompiled my assets, and I can see in Firebug that some of the functions I have declared in some of my js files in the assets folder are loading but some are not.

Edit: Just added a very simple alert function which works just fine.

Images are loading fine, styles are loading fine. Have rails_12factor gem and have run bundle exec rake assets:precompile. Can anyone point me in the right direction in terms of debugging?

Answer 1

So, I was getting this error;

'undefined' is not an object (evaluating 'f.msie')

which was resulting from one of the plugins using $.browser which has since been removed.

Installed jQuery migrate gem, re-pushed code, all jQuery and javascript now works.

Thanks to anyone who took the time to look this over.
