I am creating a Hosted app using NAPA on Sharepoint 2013 (Office365). I need to retrive a user from a list column and get the user's email.

SP.List.getItems with a query returns a listEnumerator correctly. However, the user field is of type SPFieldUserValue. This does not appear to have a property called User from which I can retrieve the email (the C# version of SPFieldUserValue has a User property). Any idea on how I can get the user's email in javascript?

This query will give you Author column (user) with email from a list 'Test':

/_api/Web/Lists/GetByTitle('Test')/Items?$select=Author/EMail&$expand=Author/EMail

You can replace 'Author' with any other Person/Group column.

I think that you need to use SP.Web.ensureUser method to retrieve user by it's logon name, after this you can use SP.User.email property.

SP.SOD.executeFunc('sp.js', 'SP.ClientContext', sharePointReady);

function sharePointReady() {
    //retrieve logonName

    var clientContext = SP.ClientContext.get_current();
    var web = context.get_web();
    var user = web.ensureUser(logonName);

    clientContext.load(user);
    clientContext.executeQueryAsync(onQuerySucceeded, onQueryFailed);
}
function onQuerySucceeded() {
    alert('The email address of the current user is ' + user.get_email());
    alert('The account name is ' + user.get_loginName());
}
function onQueryFailed(sender, args) {
    alert('Error: ' + args.get_message());
}

Thanks. I'm trying to get the email of a user from a list column, not the current user. Unfortunately, SPFieldUserValue only returns the Display Name and not the logon name. So this won't work. –  Sanat Gersappa May 17 '13 at 5:18
    
you also can try to use User Information List. See this example. It should store user's email. –  Alexander May 17 '13 at 6:46
