[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';
})();

Hi,

simply use this

gs.nil() method

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

I could see you marked my response as correct earlier and now it is not.

Would you mind marking my response as correct as that response was given quickly and accurately.

I think it's high time now taking all these screenshot and will be tagging the servicenow on twitter and mailing the community admin as well. You really need to learn some behaviour.

At some places I have even mentioned that your response is proper and you should also get equal credit and recognition for your comments.
