Limit the additional assignee list to only 2 users

Shree Nag — Thu, 30 May 2024 01:45:17 GMT

Hello,

Appreciate your help !
We have added Additional assignee list to incident form.
Now there is a requirement to limit the additional assignee to only 2 users.
One cannot add more than 2 users to the list.
Is that possible, If so could you please guide us on the steps to limit?

-Thanks

Shree

Hi @Shree Nag ,

Try this

function onSubmit() {

var assignees = g_form.getValue('YourFieldName').split(',');

if (assignees.length > 2) {

g_form.showFieldMsg('YourFieldName', 'You cannot add more than 2 assignees.', 'error');

return false;

}

return true;

}

If my answer helped you in any way, please mark it as helpful or correct.

@Shree Nag

you can do this using 2 ways

1) onChange on that field and check the length and show error message on form or field

2) before update/insert BR and show error message

If my response helped please mark it correct and close the thread so that it benefits future readers.

Hello,

Thank you all for the response.

I added the client script. The error message pops out when I'm adding more than 2 assignees, but I can still add the additional assignee to the bucket and I can update with more than 2 assignees.

What Am 'I missing in this client script, that avoids even adding the additional assignee to the bucket

function onChange(control, oldValue, newValue, isLoading) {

if (isLoading || newValue == '')

{

return;

}

var values = g_form.getValue('additional_assignee_list').toString().split(',');

if (values.length > 2)

{

g_form.showFieldMsg('additional_assignee_list', 'You cannot add more than 2 assignees.', 'error');

return false;

}

else

{

return true;

}

Thanks a lot for the help !
