"window.document.style.opacity=0.4"??

[Prisoner at War]

Okay, no such thing, apparently, in the DOM....

How am I supposed to tell JavaScript "turn the whole page opaque"?

Is there a "JavaScript/CSS dictionary" and a "JavaScript/CSS grammar"
about??

I've looked at several books but so far they're not exactly
"rulebooks," which is what I'd need...I need a rulebook that helps me
parse English into JavaScript/CSS....

A great part of my problem lies in not knowing what's even possible
("scope and depth"), and I hope the book "DOM Scripting" that's on its
way to me will soon shed light on DOM "grammar" and "vocabulary," but
it's not a rulebook as such, either.

Any rule or lawbooks on DOM/JavaScript/CSS??

And, for now, just how am I supposed to tell JavaScript/CSS to make
the *whole* page opaque? I can see how getElementById can work for
images and such -- but how about the whole page??

And then, on top of that, I need to be able to write "on top" of
what's been veiled by the opacity...and then return to the normal
webpage again....

Basically, I'm trying to accomplish what a simple JavaScript
alert("info info info") would do, only with my own visual effect and
style.

Is such a thing even possible??? (Again, I just don't know "scope"
and "depth" of JavaScript-CSS-DOM nexus....)

Here's what I'm looking to do:

1) Make whole page opaque onClick

2) Write on top of the page (not as an "addition" at bottom, but on
top, similar to a dialog pop-up box)

3) Return to normal page status onClick
During Stage 2, the page is not accessible to the visitor, in the
manner of a simple alert() pop-up.

Any way, hope that makes sense (and again, this is a *technical*
question, concerning what's possible, not an "aesthetic" one about
what's advisable in terms of design and usability, etc. -- thanks!)....

Just to clarify terminology, I think you mean to say that you want to
make the entire page "transparent", not "opaque". Look up the word.
It's amazing how often these terms are reversed in common usage.

Something like document.body.style.opacity=<value between 0 and 1>?

Plenty. Mozilla. MSDN. W3C.

http://msdn.microsoft.com/en-us/library/ms533043.aspx
http://www.w3.org/DOM/

Maybe it helps to with your terminology, too.

Er... What?

See above. Will work in contemporary "W3C-browsers".

Yes.

Easy. A "javascript modal window". Google is your friend.

Hmmm...well, the degree something is transparent is the degree to
which it is not opaque, and vice-versa, so it can be easy to trip up
terms, yes....

CSS uses an "opacity" property, so I guess I'm going along with
that...but yeah, I like for something to be transparent *over* my
webpage...AFAIK, it involves setting an opacity property...so, is
there even an opacity property to the whole page? Can the whole page
itself be addressed as an object? I know how to do it with images,
using "this.style.opacity=0.4" but is there a way to address the page
as a whole?

Gregor

To see the webpage itself...a textbox would appear, onClick, over the
webpage. During this time, the page would be inaccessible, in the
manner of an alert() pop-up. With another onClick, the textbox
disappears and the page (previously) "underneath" resumes its normal
character (scrollable, etc.).

Is there a way to address the page as a whole in the DOM? Is there a
way to write "on top" of the page, as opposed to only "adding to"
what's already there?

Is there, in effect, a way of "layering" the webpage, like with an
onion or Photoshop image??

OMG!! That's it -- BODY!! LOL!!!

Oh wow, thanks! Yeah, I'm going to learn a lot from these
references...hope I can piece it all together mentally...that's the
trick...but first I need the grammar and vocabulary -- thanks!

Er... What?

Exactly my feelings! ;-)

What's a "lawbook"?

Well, you know how if you want to start a business, you gotta go to a
lawyer who consults his lawbooks and tells you what you can and cannot
do (for example, prostitution is legal in Rhode Island if it's done
*indoors*! [?!])...or if you're playing "Dungeons and Dragons" and
the DM says that according to Rules 3.2.12 you can't use your +25
Crystal Sword of Death against a Level 99 Super Cleric from
Hell...well, same thing with JavaScript -- I was wondering if there
are "rulebooks" or "lawbooks" which dictate the "depth" and "scope" of
what's possible....

See above. Will work in contemporary "W3C-browsers".

So kewl! Hmmm...I can already see my next few assignments: what to do
with any older/non-JavaScript-enabled browsers!!

Yes.

Easy. A "javascript modal window".

Ah! A modal window! That's what that is!! Yes, "VK" had referenced
just such a thingamajig in another thread -- http://www.subimage.com/dhtml/subModal
-- but only now am I able to really appreciate it!

Thanks sooooo MUCH!! Maybe I can create a font or animated cursor and
dedicate it to you people here! ;-)

Google is your friend.

Actually, I wouldn't even have known the keyword...and while it's
better than the buy.com search engine (where you could enter the exact
title of a book and still not find it!), it still turns up a lot of
garbage for me (then again, I sometimes look for "hard stuff" with no
easy keyword matches)....
