老版本

下面是记录自己项目中的具体使用
1. 老版本 (可以舍弃掉 使用最新的)

//引入老版本的js


   ///根据组织ID查询出部门
   var selectDe = JSLINQ(Depeart).Where(function (item) {
                  return item.ParentID == Organiza[i].OrganizationID;
                 }).OrderBy(function (item) {
                  return item.Orders;
                  }).Select(function (item) {
                  return item;
                  });
