Re: [Flashcoders] Shorhand for if statement without else statement
Heh, that's nothing. I don't have the code available, but I once
wrote a ?: statement that was something like 16 deep.
Ah, those were the days. :)

Re: [Flashcoders] Shorhand for if statement without else statement
you could take that a bit further :
(foo) ? foo() : (bar) ? bar() : (foobar) ? foobar() : trace("sorry! no
soup for you!");
Steven Sacks | BLITZ wrote:
function foo() {
trace("foo");
}
function bar() {

(true) ? foo() : bar();

(false) ? foo() : bar();

Works fine for me. Not the best practice (I would never use it), but
just showing what's possible with inline conditionals.

Re: [Flashcoders] Shorhand for if statement without else statement
Hello :)
warning with the Boolean( o ) if your object is a number... the Boolean(0)
is false but :
var n = 0 ;
trace(Boolean(n)) ; // false
When you test a number the isNaN(n) is better i think :)

Re: [Flashcoders] Shorhand for if statement without else statement
hello :)
I don't understand you question ? why you don't use the if keyword ?
if ( isNaN(x) ) x = 0 ;
you can use the || operator too
function write ( txt )
{
var message = txt || "empty message" ;
trace(message) ;
}
write("hello") ; // output : hello
write() ; // output : empty message
if you use the cond?true:false operator to return a true value... you can
use directly the condition with the object.
if ( myObject )
{
trace("myObject exist !!!") ;
}
myObject is true if is defined and false if is undefined.
EKA+ :)

Re: [Flashcoders] Shorhand for if statement without else statement
Usually ?: notation is used specifically for quickly choosing between
2 values (picking between 2 things inline). That's a case where you
really have to have an else, otherwise you wouldn't have a value to
represent the failure case of the IF part.
If you're doing logic that isn't inline in a statement then you really
should be using the full syntax (if(...) { ... }).
So no, I don't think there is shorthand, as I don't think what you're
looking for would be a good construct to have. Then again, I could be
wrong. :)
