Limit the additional assignee list to only 2 users

[Shree Nag]

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

OR

2) before update/insert BR and show error message

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 !
