There isn’t an equivalent.

{
    "OrderID": 10248
    "CustomerID": "VINET",
    "EmployeeID": 5,
    .
    .
    .
  }

Than you would set the id in the dataAdapter :

var ordersSource =
            {
                datafields: [
                    { name: 'OrderID', type: 'string' },
                    { name: 'EmployeeID', type: 'string' },
                    { name: 'ShipName', type: 'string' },
                    { name: 'ShipAddress', type: 'string' },
                    { name: 'ShipCity', type: 'string' },
                    { name: 'ShipCountry', type: 'string' },
                    { name: 'ShippedDate', type: 'date' }
                ],
                datatype: "json",
                url: orderdetailsurl,
                id: "OrderID",
                async: false
            };

At least that’s how I set a unique ID.
