Can I make a <textarea> and an <input type="checkbox" > invisible?

Use JavaScript and CSS to hide them or JavaScript to remove them from
the DOM tree.

If they're invisible, aren't they functionally equivalent to
type="hidden"?

There is no <input type="hidden"> in HTML, at least not that I can find.

http://www.w3.org/TR/html401/interact/forms.html#h-17.4

Perhaps you mean that "display: none" is the same as
"visability=hid den"? In that case, no. Display: none removes the
element, inline or block box and all, from the display.
Visability=hidd en makes the box invisible, but the box still takes up
space in the layout.

On that page, "hidden" is indeed one of the options on the line that reads

type =
text|password|c heckbox|radio|s ubmit|reset|fil e|hidden|image| button

I'd be shocked and deeply upset if it were ever to be dropped!

type="hidden"?

Important differences:

1. If a textarea or checkbox is set invisible using styles, their visibility
can be changed dynamically in client-side code.

2. On the other hand, if a textarea or checkbox is set invisible using
styles, then they'll be visible to anyone not using the author's stylesheet.

I use type="hidden" for data I need to pass through a form without the
user's involvement. If the data is a large block of text that would be
displayed in a textarea, then change each double quote inside the text to
&quot; and use the result as the value of the VALUE attribute of the hidden
INPUT.

<input type="hidden" name="textarean ame"
value="double-quote-encoded-data">

If a checkbox would be checked IF it were displayed, then use

<input type="hidden" name="checkboxn ame" value="xyz">

where "xyz" is the VALUE that the checkbox would have. If the checkbox would
be unchecked, then either don't write anything out at all, or write

<input type="hidden" name="checkboxn ame" value="">

depending on the exigencies of the server-side form process and platform.
Using ASP and ordinary Response variables, either way would work fine.

Wow, that was major brain malfunction I just had. Not only did I miss
"hidden" from the spec whose url I cited, but I forgot that I use
type="hidden" regularly in my pages.

As would I. It is indeed very useful. Apologies for my absentmindednes s.

Probably; but on one of my browsers it'll certainly do nothing.

Have you forgotten to set the context of what you're trying
to achieve by this? And how you propose to handle the situation
when it doesn't work?

The only browser of interest in this case is IE 6+, so what it does in
other browsers isn't important.

Then your question is not terribly interesting to me. (Did you see the
"www" in the group name? It tends to attract people interested in
authoring the www, not authoring for a Windows system component.)

Bye.
