Why not just rewrite it so as not to use iif or de ?

Outputting a hash character in an IIF() function.
I'm having trouble with this and the usual tricks don't seem to be working.
#iif(bgFlag,DE(' style=background-color: #DDFFDD'),DE(''))#
This fails. I have tried escaping the internal hash character by
doubling. I have tried to concatenate chr(35). Everything I do throws
exceptions involving invalidly paired hash characters.

RE: Outputting a hash character in an IIF() function.
Have you tried assigning it to a variable in a cfset and then displaying the
variable. Alternately, convert to RGB: style=background-color:rgb(221 255
221)'

Generally because I prefer to KNOW why I have to replace one clear line
of code with 5 lines of slightly less clear code that requires the using
a few bits more memory to store a variable I will not use any place else.

RE: Outputting a hash character in an IIF() function.
The hash simply needs to be escaped as
#iif(bgFlag,DE(' style=background-color: DDFFDD'),DE(''))#
The hash needs to be escaped twice since you are delaying evaluation.
The text:
style=background-color: DDFFDD
Is passed out of the de function as (including the quotes):
style=background-color: ##DDFFDD
That text is then evaluated by the iif to:
style=background-color: #DDFFDD

RE: Outputting a hash character in an IIF() function.
Actually, if I am going to use braces, I like them to align vertically
for better readability:
if (foo)
{
bar = a;
}
else
{
bar = b;
}
But enough of this. He didn't ask for our opinions in code readability,
he asked how to escape a hash mark in an iif. (which I answered in my
previous reply.

Thanks, now I understand what is going on. I had tried three, but never
took it to four.

This is completely personal preference and a very very small matter.
But I generally find less to be clearer then more.
--
cfscript
if (foo) {
bar='a';
} else {
bar='b';
}
/cfscript
use_number #bar#
-
7 lines
VERSUS
-
use_number #iif(foo,DE('a'),DE('b'))#
-
1 line.
But each to his own. I still wanted to know WHY it was not working and
now I do.
