Check for unique match possible via indexOf()?

[Zod]

Hi,

I'm using a indexOf Function, but need to know if there is exactly only one match?

Something like

if (variable.indexOf(key) == 1) {

was what came into my mind ... but it does not work ;-(

Could you please help out?

Thank you

I'm checking for one sys_id.

If user is in one relevant group - it works

if in none it works (> else)

if in more than one - it works (>else)

if in 1 & one with 2 types (only one matches condition) it goes into the == 1 ... instead of the else path

Can you cite some examples? I'm not following the logic for some reason. I thought your requirement was like this:

Group A: type 1, 2, 3

Group B: type 4

Group C: type 2

User X is in group A and B

User Y is in group B

User Z is in group C and A

If you ask the script I wrote "Is User X in exactly 1 group of type 2?" the answer is the sys ID of group A.

If you ask the script "Is User Y in exactly 1 group of type 2?" the answer is null/empty (because it only belongs to group B, which is only type 4.

If you ask the script "Is User Z in exactly 1 group of type 2?" the answer is null/empty (because it belongs to two)

Keep in mind, the code above is untested so I'm going on the INTENT of the code to write the above statements.

The question would be how many groups with a type 2 is the user assigned to. The answer should be 2. So not matching ==1

sorry that I was not more specific from the beginning.

And if the answer is 2, do you want an array of both sys_ids? what should the function return? What exactly is the output you expect? a "2"?

[Zod]

No. 2 is Else condition.

i only want the group if there is only one match.

I auto assign group with this only if only one match for relevant group is found
