OK, now we know how to deal with him.


The answers seen so far have ignored the most important consideration,
which is that of what the designer of the application wants the output
to look like.

Sometimes the output should form part of a running sentence, in which
case writing into a SPAN element is best. Or maybe an I or a B or a TT
element, if the output should be italic or bold or monospace; or CSS can
be used to style the element.

But if something resembling a form is used, perhaps with FIELDSETs,
buttons, checkboxes etc., it may well be appropriate to use an output
element that looks like a little window, such as is (or was) often found
on measuring instruments; and an INPUT TYPE=TEXT READONLY serves well
for that, especially if READONLY elements are given, as is done by
Safari, a slightly non-white background.


The two lines of code that someone gave to set an element with
getElementById and .innerHTML should, if used more than about twice, be
implemented in a function :
      function Wryt(ID, S) { document.getElementById(ID).innerHTML = S }
unless of course the reference is saved for future use.
