Can an email address be added to a multi-user People Picker field using JavaScript

email address directly not.

you have to insert kind of 'user object' into PP field. email address might used to identify/create that user object, as far as the adress is unique, which need not be the case.

I've managed to get the first chosen names' email via Lookup calculation, but subsequent emails do not append.

I guess you used a lookup() runtime function.

the function doesn't support multivalue inputs, hence it recognizes and resolves just first user entry.

I assume you're going to send notifications from workflow and you don't need to know mail addresses within form.

then I'd suggest to perform lookup form respective mail addresses within the workflow, it'd be much easier.

Does the external list have email addresses or other fields that could be used to get the email address from Active Directory?

Also, would it be possible to source the names from a standard SharePoint list? You could then add a people/group column to the list that would allow easy access to the user's email address.

Agreed that looking up the actual email address is easier in the workflow than in the form.

Thanks for the replies.

Using an external list of names, ie: Last Name, First, the people are chosen.

This list also has their email address in a seperate column.

The issue I have is the List Lookup Multi-Select doesn't allow Connection to a column that supports more than 255 characters.

Nintex doesnt' allow List Lookup to Connect to a multi-line text box.

The only options I see is:

 Use a single drop-down for the names, calc Lookup the email, append it to a Multi-line textbox using a javascript button.

Hi emha,

Correct I've used a Lookup runtime function to pull the email address.

So not my ideal solution, but if I used a single list-lookup drop-down, and the email is extracted to a calcuated field each time a name is chosen:

Do you know of a way using Javascript to copy that email address and append it to a multi-line text box?

yes, that could be workable with a javascript.

buut I miss the point why would you need to resolve mail addresses in the form....

Hi emha, The reason for the email addresses on the form is due to the 255 Character limit for List-Lookups.

I thought it easier to copy the email addresses to a multi-line text field, seperated by semi- colon, then use that field in the workflow to send an email.

Either way, Full Name or email address, I would like to append that value to multi-line text box if it's possible?

Thanks. 

The reason for the email addresses on the form is due to the 255 Character limit for List-Lookups.

I meant it: why would you need to resolve mail addresses in the form and not to do that in workflow.

as mentioned, in workflow it would be much easier and you wouldn't be limited by form control's size restriction.

of course you need find/resolve mail addresses first for selected list of users before sending mails out.

but yoou need not to do that in a form, you do not need mail addresses in the form at all.

in workflow use Query list action to get mail addresses from your 'Exterenal list' of users.
