Where does your the syntax for the event name 'ajax:success' come from?
In prototype you can use the event name 'dom:loaded', although I can't
find much information about where that name comes from either, but in
any case that is prototype--not jQuery.

No. json format has nothing in particular to do with ajax.

No. Defining a variable and assigning it a value
doesn't send anything to the browser. Instead, rails will attempt to
render the
page 'action_name.js.erb', and of course on that page any @ variables
created in the action will be available.
