form表单序列化之后追加字段

 var data = $.param({‘state‘: state}) + ‘&‘ + $(‘#desProForm‘).serialize();

function saveProDes() {
    var data = $.param({‘state‘: state}) + ‘&‘ + $(‘#desProForm‘).serialize();
    $.ajax({
        type: "post",
        url: "savePro.do",
        data: data,
        success: function (data) {
        }
    });
}
