Batch operations using CSOM in a Sharepoint 2013 hosted app

Hi All,

I have a SharePoint 2013 hosted app and use CSOM queries to create multiple list items. After executing my query usingclientContext.executeQueryAsync(onQuerySucceeded, onQueryFailed); I want to retrieve the ID's of the newly created items without additional queries. I am assuming they are already in theargs parameter of onQuerySucceeded(sender, args) function. Am I in the right direction and if I am how do I retrieve all of the ID's of the newly created items? Here is the core of my code:

    function createListItems(selectedItems, Username) {
        var itemArray = [];

        var hostUrl = decodeURIComponent(getQueryStringParameter("SPHostUrl"));
        var appUrl = decodeURIComponent(getQueryStringParameter("SPAppWebUrl"));

        var oWebsite;
        var oList;
        var numItems = selectedPMs.length;

        var clientContext = new SP.ClientContext(appUrl);
        var appContextSite = new SP.AppContextSite(clientContext, hostUrl);

        oWebsite = appContextSite.get_web();
        oList = oWebsite.get_lists().getByTitle("MyList");

        for (var i = 0; i < numItems; i++) {
            // getItem is my own function
            var orgData = getItem(selectedItems[i]);

            var itemCreateInfo = new SP.ListItemCreationInformation();
            var oListItem = oList.addItem(itemCreateInfo);

            oListItem.set_item('CustomerID', Number(orgData.CustomerID));
            oListItem.set_item('CustlocID', Number(orgData.CustomerLocationID));
            oListItem.set_item('Description', orgData.Description);
            oListItem.set_item('EnteredBy', Username);
            oListItem.update();
            itemArray[i] = oListItem;
            clientContext.load(itemArray[i]);
        }

        clientContext.executeQueryAsync(onQuerySucceeded, onQueryFailed);

    function onQuerySucceeded(sender, args) {
        // I am assuming there is some returned data in args, if there is
        // I want to be able to retrieve and use the ID's of the
        // newly created items after extracting them from args
    }

    function onQueryFailed(sender, args) {
        alert('Request failed. ' + args.get_message() + '\n' +   args.get_stackTrace());
    }
}

There may be other ways to do it, I am not insisting in the args parameter. The most important task here is to avoid extra calls to server because I may be processing a batch of 100 items so I don't want to have to make a server call to read one item's ID.

Thanks in advance!
