Doesn't crash IE on my system using document.body for dW. Where does dW
point to?

dW is just another DIV, and "html before" and "html after" each
represents 100+ lines of html code. Of course I can potentially
eliminate the code line by line and find out the culprit but I'm not
going to do that because it works now anyway and the problem is too
weird that I have absolutely no idea what to look for. I mean, can you
imagine ANY situation where:
"<label for='m-bh'>Height:</label><input type='text' id='m-bh'/><br/>"
works
and
"<label for='m-bh'>Height:</label><input type='text' id='m-bh'/>"
doesn't?
I mean, WTF??

Neither are valid HTML, both trigger error correcting modes in IE, if
you're going to avoid a bug, the first thing is to have valid
fragements. IE don't use XHTML in a non-HTML user agent. It's likely
simply that the BR doesn't trigger whatever error recovery IE is doing
to be able to parse the crap you're freeding it.

You appear to be trying to escape literal line terminators. ECMA 262
explicitly forbids that when it says (in section 7.2) "A line terminator
cannot occur within any token, note even a string literal.". So crashing
IE may be an extreme example of not working, but failing to execute
would be a reasonable expectation of this code as written.

<br /> has nothing to do with your problem. You simply cannot break
string literal by new lines, it's not Visual Basic here ;-)
HTML+= "<label for='m-bx'>X:</label><input type='text' id='m-bx'/>";
HTML+= "<label for='m-by'>Y:</label><input type='text' id='m-by'/>";
.... will fix your problem.

OK fair enough. I always thought this is pretty safe hack for a more
readable code. Obviously I had a lot of bad influence over the years :-)

However, the following renders just fine on IE6, FF and Opera: http://playground.jwscripts.com/js-lineseparator.php
So it appears that in some cases, line separators can be applied just
fine...

That is so amazin - I'm speachless! I confirm it works just fine for IE
6.0, FF 1.0.7, Opera 8.1
Of course the escape sign \ must be the very last in the string to kill
the new line terminator (or its 1st part in Windows). That could be the
issue in OP.
Naturally it means *a highly extended reading* of what string literal
means in the program code. As there are not any mentions of this in
official ECMA / JavaScript / JScript docs, I say it's an expoit of the
model behavior ambiguty rather than a new feature.
I'm just dying to know if it was possible on 4th browsers too (Dr.
Stockton, are you here?!) If so then the solution was right in front of
us all these years.

It's worked just about everywhere always, the big difference is what
is in the string, some UA's have a \n in the string, others don't.

It's been generally possible for years, it's still a bad idea, as
Richard Cornford noted, it's not part of ECMASCript, it's an
extension, and as it doesn't add anything we can already do, there's
no point taking the risk.

Hello,
I was wondering what is the correct way to handle special characters
via javascript and the DOM. I would like to avoid document.write and
innerHTML. What I am doing is dynamically creating options for a

explorer, but is this the accepted way of dynamically adding special
characters.
