RE: multiple case values in switch statement in cfscript
Please, no pictures. :P
It's just once around the block in c++ land. :)
I taught myself c++ a few months before I got into CF thinking it would help
me get a good job... Since then I've never been asked to do anthing but CF,
ASP and JavaScript. But when I started working with CF I was thinking
something similar about -- "So, how do I cascade my case
statements???" ... :P
And technically, the cfscript syntax gives you more control.

Yes it is.
CFScript uses standard C/C++/Java/JavaScript syntax for switch/case, so the
cfscript equivalent looks like this:
switch (exp) {
case "a": { ; }
case "b": { .. do something ... }
case "c": { .. do something ... break; }
default: { ... do something ... }
}
The case expressions cascade, so from the point that your case evaluates, to
the point that you insert a break; in your case statements is what portion
of the code will execute, thus, if the value of exp is a or b, in the
example above, all of the actions ( or lack thereof in the case of a ) will
occur for cases a,b and c. If the value of exp is c then only the action for
c will occur. The default actions will not be processed unless something
other than a b or c is found in the value of exp because of the break; at
the end of the actions for c.

RE: multiple case values in switch statement in cfscript
One option might be to selectively use your break; command in the switch
statement.
If muliple cases can do the same code try
switch (theVar){
case "val1":{
setAVar = 'it was case 1';
break;
}
case "val2":
case "val3":{
setAVar = 'it was case 2 or 3';
break;
}
case "val4":{
setAVar = 'it was case 4';
break;
}
}
I _think_ from what I remember reading that it'll keep processing until
it hits a break;
Their might be a cleaner way to implement the case statements too, but
it works from my quick tests.

I don't think this is possible. If you get an error when you try it,
that would confirm things :-) I think it might be to do with CFScript
being kept as close as possible to JavaScript. Use if
necessary...

RE: multiple case values in switch statement in cfscript
Nope -- you can include empty case statements without a break; and they will cascade down into the following case statements until it finds a break; It's definitely doable ( see my previous post ), it's just that the syntax is _very_ different.

Yes it is.
CFScript uses standard C/C++/Java/JavaScript syntax for switch/case, so the
cfscript equivalent looks like this:
switch (exp) {
case "a": { ; }
case "b": { .. do something ... }
case "c": { .. do something ... break; }
default: { ... do something ... }
}
The case expressions cascade, so from the point that your case evaluates, to
the point that you insert a break; in your case statements is what portion
of the code will execute, thus, if the value of exp is a or b, in the
example above, all of the actions ( or lack thereof in the case of a ) will
occur for cases a,b and c. If the value of exp is c then only the action for
c will occur. The default actions will not be processed unless something
other than a b or c is found in the value of exp because of the break; at
the end of the actions for c.

RE: multiple case values in switch statement in cfscript
Woops! sorry didn't see the "in cfscript" part.
Guessing...
switch(#variabel#){
case a:
case b:
case c:
break;
case q:
break;
}
if that doesn't work, then it wont work.

RE: multiple case values in switch statement in cfscript
yes, but not exactly as you hoped...
Keep in mind that when a case evaluates to true, CF will execute EVERYTHING
until it finds a break statement...
so this would do what you want...
switch( someVal ){
case "a":
case "b":
case "c":
case "d":
case "e":
[execute some code]
break;
}

Re: multiple case values in switch statement in cfscript
Don't think it's possible to specify a list like that with cfscript. You would need five different case statements. Not sure whether you can do this in cfmx.

No it is not. Each case must be listed individually. If you really must use a single case for multiple values you will have to move to tag syntax (). -Original Message- From: Kola Oyedeji [mailto:[EMAIL PROTECTED]] Sent: Thursday, October 10, 2002 11:11 AM To: CF-Talk Subject: multiple case values in switch statement in cfscript Hi Could anyone tell me if its possible to define multiple case statements In a switch block in cfscript..
