页面javascript:

var model = {"NumberOfCPUs":"2","NumberOfCores":"4","OSType":"Linux","OSVersion":"???"};

        var id = 0;
        var success = false;
        //send to server:
        $.ajax(
            {
                async: false,
                data: JSON.stringify(model),
                dataType: "json",
                type: "post",
                url: serverSideURL

            });

实际发送到服务器的请求的内容:

{"NumberOfCPUs":"2","NumberOfCores":"4","OSType":"Linux","OSVersion":"jQuery19107363727174233645_1373301489648?"}

怎么了？是字符串"???" 某种特殊的控制词或jQuery中的某些东西？

谢谢.
