Actually, in MX the CFScript version of switch
allows you to stack multiple case values and uses the break command. This
makes it much more powerful than CFSwitch and gives you all the features of the
JS switch statement.
switch(arraylen(arguments)) {
case "1": argument2 =
yadda;
case "2": argument3 = yadda;
break;
case "3": case "4": argument1 =
yadda;
}

That works with CF in CFScript also... I like to use it with
functions
sometimes for the number of arguments:
switch
(arraylen(arguments)) {
case "1": { argument2 = yadda; }
case "2": {
argument3 = yadda; }
default: { yadda; }
}
Makes it a little
easier than having multiple comparisons of the
number of
arguments.
The delimitered case statements are a bit different -- you
can't have
the same value in two case blocks, so for instance you can't
say:
<cfcase value="1"></cfcase>
<cfcase
value="1,2"></cfcase>
Delimiters are nice, but they still
don't allow quite the same
functionality as the cfscript switch statement
(granted, you don't get
delimiters in cfscript either, so there are pros
and cons either way).
Personally I think it would have been nice if they'd
provided a way of
allowing the tag-based case statements to cascade,
like
<cfswitch cascade="true">
<cfcase
value="1">
blah blah blah
<cfbreak>
</cfcase>
<cfcase
value="2"></cfcase>
<cfcase
value="3"></cfcase>
</cfswitch>
Which would allow you
to get the same functionality from a tag-based
switch. But it's such a
"one-off" feature (so infrequently mentioned)
I doubt it'll ever be
implemented.
