Weird, I'm not sure why they would have an input tag that had no type or
name attribute, unless they were using to display something visually that
wasn't processed when submitted.
The other type, type=hidden, is very common though. This is how variables
are passed along with the rest of the form information when the form is
submitted. These are hidden values, so none of these are displayed. You
can't even set focus to these manually by calling the focus() method on the
element. You could check the value attribute and name attributes of these in
the script though, if you are curious about what types of values are also
being passed with the form.
