how to turn off meta-refresh ?

[dan baker]

I have a page that gets loaded with a meta-refresh hardcoded so that a
few things on the page get updated. its kind of a fake chat board.
anyway, what I need to do is turn off the meta-refresh once someone
clicks in a <textarea> to enter their input; otherwise the refresh
catches them in the middle and messes up the focus.

I need a way to turn off the meta-refresh, or to force the
cursor/focus to stay in the message input box once they click in it
and start typing.

I've tried:
<p class=small>Enter your new message:
<br><textarea NAME=NewMsg rows=2 cols=60 wrap=virtual
onClick="window.location.reload(false);"></textarea>
<br><input TYPE=submit value="Post Your Message" >

but this actually forces a refresh onClick ?!

You cannot cancel what has been parsed before, but you can cancel what
you have set before with JavaScript, so change the meta-refresh into a
window.setTimeout(...) call and cancel the timeout when necessary:

if (window.setTimeout)
var iTimeout =
window.setTimeout('if (location.reload) location.reload();', 42);
....
<... onclick="if (window.clearTimeout) window.clearTimeout(iTimeout) // one
line recommended">...</...>

<p class=small>Enter your new message:

BAD. Broken as designed. See

That's right. The "reload()" method does cause the window to
reload immediately. The "false" argument simply means that you
don't want to force a new download if the page is already in
your cache.

Guessing won't get you very far. Find a book or some of the
on-line resources listed in the FAQ.

I don't believe there is any way in JavaScript to disable the
REFRESH directive. Since your page seems to rely on Javascript,
anyway, you would be better off not using the HTTP REFRESH
directive, but using JavaScript to refresh the page periodically.

Look into setInterval(), clearInterval(), and, of course,
location.reload().

--------------------

thanks for the help people... I did more reading and found an even
slicker way to do it with setInterval(). The basic sticking point that
you solved for me was that the refresh had to be started with
javascript rather than coming in hardcoded. Anyway, I thought I would
post the snippet in case someone else needs it:

<SCRIPT LANGUAGE="JavaScript1.1">
<!-- hide script from old browsers...

// always start auto-refresh onLoad
var RefreshID = setInterval("window.location.reload()",10000);

function StopRefresh(){
clearInterval(RefreshID);
}

function RestartRefresh(){
RefreshID = setInterval("window.location.reload()",10000);
}

// -->
</SCRIPT>

<td>
<a name=bottom></a>
<textarea NAME=NewMsg rows=2 cols=60 wrap=virtual
onFocus="StopRefresh();return true;"></textarea>
<br><input TYPE=submit value="Post Your Message" >
</td>
thanks again.... d

That's invalid HTML, AFAIK only IE for Windows will accept the code. The
`script' element requires a `type' attribute to define the MIME type of
the code. And the `language' attribute is deprecated. If you use it for
backwards compatibility with older user agents, do not specify the version.

I do not see the point of defining an interval (a *self-repeating* action)
here. A timeout that is cleared when focusing the `textarea' element (and
reset on blur, if you like it) should suffice and is more compatible because
it is supported since JavaScript 1.0, while window.setInterval(...) requires
JavaScript 1.2 support. (I'm aware that recent UAs support at least JS 1.2.)

Also I do not understand why you are defining the global variable at first
(and *before* the document is loaded). To restart the refresh interval
(better: timeout; see above) you define a function that redefines that
variable, why don't you call the function onload? That would simplify
programming and maintenance.

It is good style to reference properties by their object, even if it is not
required with `window', and it is also good style to check properties for
existence before accessing them.

Summary:

<head>
...
<script type="text/javascript" language="JavaScript">
<!--
function stopRefresh()
{
if (window.myRefresh /* global variables are properties of the
container object; no property, no
clearing necessary */
&& window.clearTimeout)
window.clearTimeout(myRefresh);
}

function startRefresh()
{
if (window.setTimeout && window.location && window.location.reload)
myRefresh = window.setTimeout("window.location.reload()", 10000);
}
//-->
</script>
...
</head>

<body>
<form>
...
<textarea name="NewMsg" rows="2" cols="60" wrap="virtual"
onfocus="stopRefresh();" onblur="startRefresh();"></textarea>
...
</form>
<script type="text/javascript" language="JavaScript">
<!--
/*
* Timeout should start when the document has been completely loaded,
* but the `onload' event handler is not supported by all UAs, so we
* place the script at the end of the `body' element.
*/
startRefresh();
//-->
</script>
</body>

No, the vast majority of browsers will, in fact I don't know of any
which won't (either taking it as their default type or understanding
the language attribute) It's not even an IE invention, so I'm not
sure where you got the idea.
The
`script' element requires a `type' attribute to define the MIME type of
the code. And the `language' attribute is deprecated. If you use it for
backwards compatibility with older user agents, do not specify the version.
There's no reason to include it for anyone, you don't get any extra
compatibility with older browsers, other than in IE 4 in a particular
perverse scenario which I don't believe exists.
while window.setInterval(...) requires
JavaScript 1.2 support. (I'm aware that recent UAs support at least JS 1.2.)
setInterval has nothing to do with the javascript level, it's a DOM
object, although in effect "all" UA's less than 5 years old support
it.
if (window.myRefresh /* global variables are properties of the
container object; no property, no
clearing necessary */
There's no requirement that variables be part of a global object
called window, the global object could be called fred, the only UA's I
know which do this are not HTML ones, but I doubt their unique, I also
know of UA's which don't put their global variable as part of the
window object and the above check would fail - I wouldn't recommend
doing it)

Please name such a UA!

Actually, it does. Javascript is a product of Netscape Corp. which is
used in its browsers. Other browsers have also implemented similar
languages under similar names, but the definition of Javascript v1.2
is ... hmm, unavailable. However, they do have 1.3 online, and as part
of that specification, they define the window object:
<URL:http://devedge.netscape.com/library/manuals/2000/javascript/1.3/reference/window.html>

This (Javascript 1.3) specification states that the object "window"
has the method "setInterval". I.e., "setInterval" is part of
Javascript 1.3.

It makes no sense to talk about Javascript levels apart from
Netscape's specifications. There are similar specifications of
different versions of JScript.
I also know of UA's which don't put their global variable as part of
the window object and the above check would fail - I wouldn't
recommend doing it)

Do you know of *browsers* that don't have a global variable called
"window" that points to the global object (and which support
ECMAScript-like scripting at all)?

I believe that the current draft of the next version of SVG DOM
includes references to the object called "window" with a "setInterval"
method. Can't find a single reference to it right now, though.

What is the UA that has a window object separate from the global object?

No worries, we can see it's gone in JavaScript 1.5 then, so therefore
Mozilla browser's don't support setInterval? That's good to know.

However, I believe you're falling into the trap of confusing the
DOM/script documentation from Netscape which has always confused the
two, that's just a weakness of the documentation.

Yes, I've discussed it before, CSV is the most recent one, it's still
a a browser, seen as it's in no standard that the global object is
called window, it seems rather silly to do it such.

I guess it is a matter of wording.
The window object isn't in the Javascript 1.5 *Core* Language.
But, as you say, they are not very explicit about the difference
between the core language and the language included in the browser,
calling both "Javascript".

I will maintain that javascript 1.2 was not defined in terms of Core
language and browser/client extensions, but was seen as a whole.

Terminology has changed since then, with the introduction of the
concept of a DOM. What-is-now-DOM methods such as setInterval, Image,
Option, etc. were then just part of Javascript 1.2.

That means that not only are there changes to the language, there are
also changes to how we think about it. Having two different
perspectives at the same time is bound to give problems. :)
Yes, I've discussed it before, CSV is the most recent one, it's still
a a browser, seen as it's in no standard that the global object is

I can't find this CSV browser through Google (the most used menaing of
CSV seems to be Comma Separated Values). Even checked all you wrote
about it in this group, but no explaition of CSV except Comma
Separated List..
ASV3 and 6 and CSV.

.... and ASV seems to mean Action Script Viewer (apparently for
Shockwave). Ah, there. It is also Adobe SVG Viewer. That would make
CSV ... Corel SVG Viewer? :)

I'll look into them.

Well, it is called attribution _line_ (and not attribution novel) for the
reason that it should only provide information who wrote the quoted text,
especially when there is more than one quoting level. The other information
(like message ID, newsgroup(s) name, the sender's address, posting date and
time) can be easily retrieved via and from the headers of the postings by
people who are interested in it. On the other hand, this overhead is fitted
to make a posting less readable. (The newsgroup name and message ID in this
e-mail is only included to help you find the posting I am referring to,
because this is a different medium and not all e-mail user agents support
showing/clicking headers like `References' or `In-Reply-To'.)

I need not to provide a reference to a Usenet standard that recommends
this (although there may be one) because common sense should be enough to
recognize it, and if you call me silly for merely *asking* for a readable
posting, that is *your* problem.
Please do note that I did not want to discuss there here off-topic in
the first place, but you leave me no choice:

Evidently you do not understand what headers are and what their function

Evidently you do not know of news archives like Google Groups,

Evidently you are unable to provide a reference to a Usenet Standard

Evidently you do not understand what a readable posting is, and
that you write for your readers, not for posing yourselves.

Please do note that I did not want to discuss there here off-topic in
the first place, but you leave me no choice:

Since you make inappropriate complaint about newsgroup postings, it is

^^^^^^^^^^^^^^^^^^^^^^^ in the newsgroup that you must be shown to be incapable of justifying
your unfounded assertion.

It was merely a plea along with an on-topic and (hopefully) a helpful
answer. In contrast, your answers and the subject of my plea are completely
off-topic here.

And evidently you do not even think about paying respect to core Internet
and Usenet standards, namely not using a valid e-mail address (as stated
by RFCs 1036 and 2822), not having installed the `postmaster' account for
your(?) sub-level domain (as stated by RFC 1173), and not obeying the core
rules of Netiquette (RFC 1855), so I do not see the point of discussing
the justification of (my) statements by those standards with you.

setInterval has nothing to do with the javascript level,

it's a DOM object, although in effect "all" UA's less than 5 years
old support it.

Before the W3C-DOM (October 1998) there was no idea of a DOM, and what we
call host objects of a DOM now were previously part of the core language.

http://devedge.netscape.com/library/...w.html#1203669

(Find the setTimeout(...) method originating from JavaScript 1.0 in the
same document.)

The W3C-DOM Level 2 Candidate Recommendation called that part, supported
by Netscape Navigator 3.0 and Internet Explorer 3.0, "DOM Level 0":

http://www.w3.org/TR/1999/CR-DOM-Lev.../glossary.html

Namely Netscape Navigator up to version 4.x implemented the next versions
of javascript:

http://devedge.netscape.com/library/...e.html#1003267

With Mozilla/5.0 implementing JavaScript 1.5 (which is based upon
ECMAScript Edition 3), those UA dependent parts have been moved from
the Core Reference to the Gecko DOM Reference:

http://mozilla.org/docs/dom/domref/

if (window.myRefresh /* global variables are properties of the
container object; no property, no
clearing necessary */

There's no requirement that variables be part of a global object
called window, [...] I also know of UA's which don't put their
global variable as part of the window object and the above check
would fail - I wouldn't recommend doing it)

You are right, the proper way is

window.myrefresh = window.setTimeout(...);

adding explicitely a property to the `window' object. Then the property
can be checked for existence so that the timeout is only cleared if one
has been set before.

* Timeout should start when the document has been completely loaded,
* but the `onload' event handler is not supported by all UAs, so we
* place the script at the end of the `body' element.

Please name such a UA!

The `onload' attribute was introduced in HTML 4.01, so
all user agents supporting only HTML 3.2 will ignore it.

You are right, the proper way is

I don't see the point of using references relative to - window - in this
context. The interpreter is going to have to resolve the references to -
window - by traversing the scope chain to the global object, which is
exactly what it would have to do to resolve - myrefresh - or -
setTimeout - if used in isolation. The difference seems just to be that
with the - window - reference a second property look-up is needed on the
object referenced by - window - (assuming the global window property
exists in the environment). If the scope resolution is in question then
that applies equally to - window - as it would for - setTimeout - and
otherwise using - window - imposes a performance penalty without any
reliability gain.
adding explicitely a property to the `window' object. Then the property
can be checked for existence so that the timeout is only cleared if one
has been set before.

A type-converting-to-boolean test on an undeclared global identifier
will produce errors where the same test on the property accessor of a
non-existent global property will not, but typeof tests do not suffer
the same problem so the property accessor syntax is not required when
testing global properties/variables (just potentially useful under some
circumstances).

Why? You have been asked to cite a (any) Usenet standard that will
support your request and so far you haven't, and your argument to date
seems to hinge on stressing the word "line" in "attribution line". If
line means CR (&/|) LF terminated sequence of text I could make the
above into one line by just setting the margins in my news software to
110+ characters and apparently satisfy your criteria. I can see no
reason for doing that as the chances are that it would still be viewed
as two or more lines in most newsreader software, and even your 24
character attribution of me might be displayed across two lines if the
recipient had their viewing window set up sufficiently narrow (granted
that is unlikely).

You might just as easily stress "attribution" and consider what is
required to attribute. You and I may be using identifiers that are
unlikely to be confused with others but in the UK the name John Smith,
for example, is sufficiently common that one individual using that name
would not necessarily be distinguishable from another without an
accompanying email address (even if fake). And if you are going to say
that some individual wrote something it has got to be worth saying where
they wrote it, for which the message ID is probably the most
discriminating identifier available.

I can certainly see grounds for commenting on excessive (and irrelevant)
content in "attribution lines" but if you want to take the term that
literally can you justify loosing "attribution" for the sake of "line"?

<snip>The whole point is that I check the variable/property before I

Reasonable, but that could still be done with a typeof test.
Because of what Jim stated above I use the `window' object and

Are you saying that the setTimout/Interval call must follow - window. -

by NetNews software, and RFC 1036 which an important base of NetNews calls
itself `Standard' but is not even on the IETFs standards track. Sum: Not
everything must be standardized to be reasonable and therefore acceptable.
and your argument to date seems to hinge on stressing the word "line"
in "attribution line".
No, re-read my answer(s). It hinges on the easy readability of a posting/
thread which is a Good Thing. Header information included in the attribution
line that may be *someday* of use for *someone* doesn't compensate for a
more difficult following of a discussion, mentally ignoring superfluous
information when reading *now*.
<snip>

The whole point is that I check the variable/property before I
am accessing it in the window.clearTimeout(...) call.
Reasonable, but that could still be done with a typeof test.

I did not doubt that.

Because of what Jim stated above I use the `window' object and
create a new property, as for the timeout the `window' object
is used anyway.

Are you saying that the setTimout/Interval call must follow - window. -
?

No.
That is not true.
I know, because `window' is the global object here -- as tests with
Netscape 3.0 to 7.1, IE 6 and Opera (all under Win2k) have proven.
But can you name a user agent where the global object is _not_ `window'
_and_ provides $globalObject.setTimeout/clearTimeout?
<snip>

ACK, but `typeof' was implemented in JavaScript 1.1.

And fortunately JavaScript 1.0 environments are no longer in use.

How do you know for sure?

<snip.But can you name a user agent where the global object is _not_

I don't see the relevance of this. I have been questioning the worth of
referring to properties of the global object relative to a - window -
reference because that is unnecessary and must be fractionally slower. I
do not doubt that a property accessor syntax relative to a - window -
reference will be effective on JavaScript capable HTML web browses (at
least where setTimeout/Interval are concerned) but why do that when it
is unnecessary?

ACK, but `typeof' was implemented in JavaScript 1.1.

And fortunately JavaScript 1.0 environments are no longer in use.

Nothing is known for sure, but if there were JavaScript 1.0 environments
in use this group is where I would expect to here about them. What I do
know with almost certainty is that anyone still using a JavaScript 1.0
web browser is not finding doing so a productive activity these days.

Because Netscape 4, is the only user agent that ever implemented
JavaScript 1.3 - Mozilla has JavaScript 1.5, IE has had various
JScript implementations, Konqueror and Safari have KJS
implementations, iCab and Opera have their own ECMAScript
implementations - sure we know they're all pretty similar to
JavaScript, but they are not JavaScript 1.3 (there's no watch for
example)
JavaScript 1.3 is according to Netscapes Core JavaScript Reference

You're freely allowed to add objects to ECMAScript (it would be a
useless language if you didn't, but that doesn't make your extensions
part of the language.

The information in an attribution is not contained in the header of the

You oppose yourself. If one maintains a local news archive, they would
use most certainly a software that can follow references. And if the
article expires, its posting date is barely of interest any longer.

If one doesn't maintain such an archive, they would have access to the
Internet/Usenet and can access the thread for the stored posting somehow,
in the unlikely case that this is required. If they don't have immediate
access, they would have saved the whole thread in the first place.

Then why don't you enlighten me and explain what has occured in this case?
So far I only got a bounce when sending you e-mail using the substring you
used in the `From:' header as e-mail address, and I must therefore conclude
that it is no e-mail address. So far I got a bounce when addressing the
`postmaster' account for the domain part of that substring and I must
therefore conclude that either the host is misconfigured or that this domain
cannot receive e-mail at all.

certain hosts (e.g., those that have previously sent messages to
