Restrict the use of particular mail id in a field

[suuriyas]

HI Community,

I have a requirement, in incident form we have a field called additional assignee list which is list type and reference to user table.

In this field i want to restrict the use of particular mail id let say xx@gmail.com users should not able to enter this particular mail id in that field 

How can we achieve this?

Note: we don't have any users profile with this mail id but we can able to enter it using highlighted box (add email address)

Thanks in Advance

Hi @suuriyas 
To prevent users from adding email addresses, add the following attribute to the dictionary entry 'Additional Assignee List'. This will hide the email address field.

HI @J Siva ,

Thanks for the response

Adding no_email=true; Will it restrict adding all the email id's? because i want to restrict only one mail id in this field.

let say xx@gmail.com only this needs to be restricted

@suuriyas If I'm correct, you don't want users to add any external email IDs (i.e., those not belonging to the organization). If that's the case, please proceed with the approach I shared. If someone needs to add the email IDs of actual employees, they can use the reference field to select the user

Hello @suuriyas 

Please create an on-change client script on additional assignee field.

This is how your script would look like:

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

    if (isLoading || newValue === '') {

        return;

    }

    var watchList = g_form.getValue('watch_list');

    if (watchList.includes('test@test.com')) {

        alert('test@test.com is not allowed in the Watch List.');

        var emails = watchList.split(',');

        emails = emails.filter(function(email) {

            return email.trim() !== 'test@test.com';

        });

        g_form.setValue('watch_list', emails.join(','));

    }

}

I've used test@test.com as an example.

Please let me know if you need any further help.

Please mark answer as helpful/correct if it helps.
