Thanks for taking the time to summarize; excellent. 

Sorry I repeated what you said about the attr() function; I can't type fast enough to keep up with all the thoughtful emails. ;)

I think Gavin got this sorted out but I just wanted to clarify: the end
goal is to add a "ui-mini" class to inputs here, not data-mini=true. The
data attribute by itself does nothing. The jQuery Mobile framework uses
data attributes to apply classes, among other things, so you can skip the
intermediary step and go straight to the class. You don't need to edit the
CSS with a rule like input[data-mini=true]; just use the class that's
already there.

My advice to get rid of the $(document).ready() wrapper was poor because it
means your code probably executes *before the input elements are even in
the DOM *particularly if your script is in the head. If you for some reason
have to use data-mini=true, you need to run your code *after* jQuery and
the DOM has loaded but *before* jQuery Mobile uses all those data
attributes to apply classes. Does that make sense? I'd just avoid this
execution order headache and apply the class.

Also, Michael, your quote from the jQuery API is only about the getter
usage of attr(); if handed only one parameter, attr() returns the value of
the attribute for the first item in the selection e.g.
$('input').attr('data-mini') => 'true'. But in the setter version, attr(
attribute, value ) sets attribute to value on *all *selected elements. Look
at the first setter example on the API page where they set the title, src,
and alt of three img tags at once by passing a map to attr().

Best,
Eric
