I also read about using $ or j if you're variable stores a jQuery

Maybe this might sound stupid, but what if you first do something like
this:
var $showFeedback = $('#showFeedback' +spanIdNo);
(or var jShowFeedback = $('#showFeedback' +spanIdNo); respectively)
And if you then want to store the height of that element, do you use $
or j again (-> $showFeedbackHeight = $showFeedback.height();), or do
you use a "regular" variable name because it's not a jQuery object but
an attribute?
If the value is numeric, which it is in this case, I wouldn't use the
$ or j. I only use $variableName when the value is a jQuery object.
var $showFeedback = $('#showFeedback' +spanIdNo);
var showFeedHeight = $showFeedback.height();
Of course, there isn't really a "right" way. It's just a convention
(though a useful one).
In case you're interested, this convention was first suggested by
Michael Geary back in 2006.
