Simple issue: why has this suddenly stopped working going from 1.10 to 1.11?

Simple issue: why has this suddenly stopped working going from 1.10 to 1.11?

I'm not totally new to jQuery, but I'm not an expert, and I don't keep up on all the changes from one version to another. I have one site that was originally designed using jQuery 1.10.2, and a couple pieces of simple, straightforward inline javascript have suddenly stopped working when jQuery was updated to 1.11.3. They are these:

  1. onclick="$('#login').slideDown('fast'); return false;"

and

  1. onclick="$('#bannerBar').fadeOut('fast'); return false;"

I imagine it must be something as simple as a change in syntax or a deprecated function, but I can't find anything through Google except discussions of complex problems that are several layers deeper than I understand.
