I use such as
<iframe src="someHTML.htm" onload="Procrustes(this)"></iframe>
to adjust the height of the iframe to fit the displayed
content from page someHTML.htm ; it works in my Firefoxes.
BUT
(1) I've not tested it on all browsers,
(2) If someHTML.htm contains a similar construction,
the 'outer' iframe resizes wrongly, for an obvious
reason,
(3) Validators & testers dislike iframe ... onload.
Is there a better method, acceptable to at least to
validator.w3.org, known to all reasonable browsers
including Firefox esr 52.1.1 (32 bit), and free of
unforeseen evils? If so, please explain.
I have seen method ondatasetcomplete in Wikipedia.

Indeed, but that just means asking to acertain that there will be none in that same future is pointless. Well pointless up to a point.

If so, please explain. Perhaps using Ajax to load the content within a div, combined with CORS [1] headers to allow access to cross-origin responses.

Also, any problems with validators can be circumvented by scripting event
listeners at the appropriate time:
iframeRef.onload = function () {
Procrustes(this);
};
BTW, quite an interesting name for a function :) [For those who are
unaware: Procrustes was the Greek mythological villain who ran a less
expensive hostel just outside ancient Athens that made his visitor victims
fit exactly into his bed by either stretching them or sawing off their
limbs. He was one of the three villains famously killed by Athens’ hero
Theseus (who is partly historical) using their own methods against them when
he traveled to meet his natural father, Aigeus, King of Athens (only that
Theseus beheaded the tall Procrustes instead). (I listened to the myth of
Theseus, beautifully told by Austrian writer Michael Köhlmeier, a few days
ago.)]

Alas, no! my pages start with :-
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
&
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
I also have a batch file with other minor checkers in it; it
which also has a call to an old copy of TIDY (as a checker)
and a call to an old local links checker which I once wrote
in Pascal and compiled in Delphi.
I have tended to start pages with strict.dtd and change to loose.dtd
when strict.dtd reports baffling faults; loose.dtd generally
reports things which I should have remembered were wrong. So,
for me, <!DOCTYPE HTML> is impractical.
Perhaps I should put, in a general include file, something like
function Elasticate(Sauce, DefaultHeight) {
// code to insert into DOM at this point ...
// make iframe
// iframe onload = Procrustes (this, DefaultHeight)
.. iframe src = Sauce
// end DOM code
}
and put in the HTML of the pages something like
<script ...> Elasticate("pagelet.htm", 45) </script>
"Procrustes" also occurs in the works of LVCN : Google
for Niven Procrustes to approach details.

I am now putting. for example,
<script type="text/javascript"> Ink("$compost.htm", 69) </script>
in the HTML pages, and have added the following in a commonly-included
script file.
function Ink(Sauce, DefaultHeight) { var Fram
// code to create and insert iFrame into DOM where called ...
Fram = document.createElement("iframe")
Fram.style.border = "2px solid red"
Fram.style.width = "100%"
Fram.style.margin = "0.5ex 0"
Fram.style.background = "#FFE"
Fram.onload = Inky(Fram, DefaultHeight)
document.body.appendChild(Fram)
Fram.src = Sauce }
function Inky(Ifr, ExHi) {
// Autosize works in Firefox and MS IE (Edge?), else use ExHi
setTimeout(function() { Procrustes(Ifr, ExHi) } , 500) }
function Procrustes(Ifr, ExHi) { var Ht
try { Ht = Ifr.contentDocument.documentElement.scrollHeight }
catch(e) { Ht = 0 }
Ht = (Ht==0 ? ExHi + "ex" : Ht + "px") // ; alert(Ht)
Ifr.style.height = Ht }
The setTimeout appeared necessary for the frame height needed to be
discoverable by Procrustes; perhaps there is a better way.
Sometimes, an iFrame appears further down the document than intended,
when two are adjacent.
Alas, iFrame has a minimum height.
That got rid of almost all of the iFrame onloads; a couple of special
cases needed a minor addition to the above code.

I haven't tested any of this, but even if it turns out to be necessary for some reason, 500 ms *after* the load event seems a bit excessive. It's not that I can't wait for half a second, I just really dislike elements jumping around on a page. > Sometimes, an iFrame appears further down the document than intended, > when two are adjacent. > > Alas, iFrame has a minimum height. They do not; even iframes with 0px height are possible. Use display:block. - stefan

Perhaps the onload event is fired when all of the file has actually arrived, rather than when it has been sufficiently processed for its height to be known. I will test shorter intervals; but, as I am using it, the jumping is not annoying. _At_present_, an inadequate interval leaves the iframe short ... Another problem occurred when the file in the self-adjusting frame contained a self-adjusting frame. That was easily avoided when I noticed that the inner material did not need to be framed (certain site "design" rationalisations have been done since that material was originated); un-framing it meant that no frame would be shorter than the size of <iframe></iframe>. > > Sometimes, an iFrame appears further down the document than intended, > > when two are adjacent. > > > > Alas, iFrame has a minimum height. > > They do not; even iframes with 0px height are possible. > Use display:block. While writing the above, it occurred to me that it would be easy to set the size of the infant iframe to the value of DefaultHeight provided, and adjust it later if the right height becomes known. Then, for readers whose browser window is a sensible number of em units wide, jumping will be replaced by minor hopping. Thanks. -- (c) John Stockton, near London, UK.

Yes. But I have at last realised that this JavaScript re-sizing can
never work under all necessary circumstances.
I want the pages to display well when read (or copied) from a transfer
USB memory stick, using an ordinary PC with only what Windows supplies,
though maybe using another browser instead. And I'd rather not rely on
it having a UK keyboard, or a keyboard driver that matches the keyboard.
Therefore I cannot rely on using
Iframe.contentDocument.documentElement.scrollHeight
because when reading from a local drive Chrome, at least, considers that
to be forbidden by the Same Origin Policy.
Therefore I intend, as author, to continue using Firefox, in which the
Same Origin Policy is more sensibly implemented, with "Iframe includes"
and "contentDocument", but with the Iframe height initially being set to
an initially suitable amount. Provided that the refusal of
contentDocument is silently trapped, that version will be non-ideal but
distributable.
And I have it in mind to write a pre-processor, in Windows Script Host
JavaScript, which will read file ????WXYZ.HTM, read and insert the
includes that it contains, recursively, and write file ????WXYZ.$HTM;
the (MS-DOS Batch) transfer program can easily be persuaded to omit the
"$".

For the height of the iframe itself, yes, but the OP also wrote "Sometimes, an iFrame appears further down the document than intended, when two are adjacent". Block display can be used to fix that. - stefan
