Reading up on the documentation would be a good thing, as knowing the
basics, like knowing what ".html()" does, is absolutely required if
you want to learn to use this library to the fullest
As for
"If I store the value of $(this) as shown I can later retrieve the
value
for a specific field by e.g., calling .."
No, that's not what is going to happen....
saying: origFormData["some key"] = $(this);
saves a pointer to that object, not a copy to the object itself.....
so if later on you change anything on "$(this)", you changed the value
(but is really just a pointer to the object) of "origFormData["some
key"]" as well
