Afternoon guys
Is it possible in javascript to give out 2 answers to a tenary
opertor (doesnt make sense i know - see below)
function foo(arg) {
return ($(arg)) ? true : alert('Element Does not exist');false;
}
...
(wrapped in window loaded function)
foo('baz'); // doesnt exist so i want it to alert the
alert and return false to halt the script...
div id=bar/div
Is this the right way to do it in the operator or cant it be done
and no i dont want to make 2 functions i would like it in one if it
can be done.

[Proto-Scripty] Re: ternary operators
Sorry you missed the point i was trying to achieve.
I wanted the operator to in essence evaluate 2 responses for example.
alert('Element Does not exist'); alert('The second responsee');
However it cannot be achieved so it must be done usung if/else..

[Proto-Scripty] Re: ternary operators
Hi Alex,
However it cannot be achieved so it must be done usung if/else..
Well, this is JavaScript, there's almost always a way. I can think of
four off the top of my head that keep it in a single expression -- but
all of them are much worse (most of them much, much, much worse) than
using an if/else. ;-) The four are:
1. Massage the return value of the first thing you want to do to force
it to be the return value you want. Actually, in your specific case,
you don't have to anything:
return $(arg) ? true : alert('Element Does not exist');
alert has no return value, hence your function returns either true or
undefined, which is good enough for anything branching on its return
value (undefined is falsey, after all). If you really want a false,
use !! to force it.
Blech.
2. If you wanted to return something other than false, and if the
first part has an invariant result, you could manipulate that return
value to be falsey and use the OR operator, which is much more
powerful in JavaScript than in most languages (more here[1]):
return $(arg) ? It's there : (alert('Element Does not exist') ||
It's not there);
or, demonstrating manipulation:
return $(arg) ? It's there : (!setTimeout(...) || It's not there);
...since setTimeout returns a non-zero number; !setTimeout is false
and so the return value (for that second operand) is It's not there.
Blech blech.
3. Wrap the two-part bit in an on-the-fly function:
return $(arg) ? true : (function(){ alert('Element Does not exist');
return false;})());
Blech blech cough.
4. Use eval (!):
return $(arg) ? true : eval(alert('Element Does not exist'); return
false;);
Blech blech cough retch.
I bet there are others.
So: *Possible*, but if/else is just a way better way to go. ;-)

Subject: [Proto-Scripty] ternary operators
Afternoon guys
Is it possible in javascript to give out 2 answers to a tenary
opertor (doesnt make sense i know - see below)
function foo(arg) {
return ($(arg)) ? true : alert('Element Does not exist');false;
}
...
(wrapped in window loaded function)
foo('baz'); // doesnt exist so i want it to alert the
alert and return false to halt the script...
div id=bar/div
Is this the right way to do it in the operator or cant it be done
and no i dont want to make 2 functions i would like it in one if it
can be done.
Regards
