There is a form with 3 squares in it

My question is if I A tip class is a "hat-tip" to give help to "form-tip" and a square of each input, how can I always look at the last "form-tip" div?

Something like this:

  $ ('is-tip') each (focus (function () {var tip = $ (this) .attr ('title' ); // Find the most recent $ ('. Form-tip') fill it with the dome and tip}});  

I hope that makes sense .. Thanks for any help.

if .has-tip If you have a child's .form-tip you can use it like this:

  $ ('.has-tip') each (focus (function () {Var tip = $ (this) .attr ('title'); var ft = $ (this) .closest ('form-tip'); / / Most recent $ in DOM ('. Find and reply it with a tip}});  

If it is a brother, you can use it or if it immediately is not before, so it is.
