使用javascript从sharepoint人员选取器中检索电子邮件地址

var clientContext = new SP.ClientContext();
var list = clientContext.get_web().get_lists().getByTitle('Your List Title');
var listItem = list.getItemById(itemId);
clientContext.load(listItem);
clientContext.executeQueryAsync(function() {
  var fieldValue = listItem.get_item('Your People Picker Field Internal Name');
  var emails = fieldValue.map(function(person) {
    return person.get_email();
  });
  console.log(emails);
}, function(sender, args) {
  console.log(args.get_message());
});

var url = _spPageContextInfo.webAbsoluteUrl + "/_api/web/lists/getbytitle('Your List Title')/items(" + itemId + ")";
$.ajax({
  url: url,
  method: "GET",
  headers: {
    "Accept": "application/json; odata=verbose"
  },
  success: function(data) {
    var fieldValue = data.d.YourPeoplePickerFieldInternalName;
    var emails = fieldValue.map(function(person) {
      return person.Email;
    });
    console.log(emails);
  },
  error: function(error) {
    console.log(JSON.stringify(error));
  }
});
