how to check for a empty string

[Raffi]

I am giving the input as numbers ...ex(11011748,11011749)

I am trying to check for an empty string.

but it returns empty , even if i enter a string.   -> (11011748,11011749)

Code sample

answer = (function () {
if(current.variables.clabel === "")    //-----> my code to check the empty string
{
workflow.scratchpad.comments = 'Given label is Receiver Label';
return 'no';
}
return 'yes';
})();

please help

i tried marking both the answers a correct

gs.nil(current.variables.clabel))

current.variables.clabel.nil()

both seems to be correct, i tired to mark both as correct, 

but the algorithm accepts only one...

other gets disabled...

sorry for that...

No worries.

You can mark whichever you used and worked well.

Stay safe.

Hi,

hmm, === operator should work , but you can use gs.nil as Ankur stated or nil()

(current.variables.clabel.nil())

mark Correct✅/helpful if applicable, thanks!!
