Javascript 如何为datatables服务器端处理返回JSON对象

我需要使用服务器端处理将一些数据加载到datatables表中

我需要将一个自定义JSON对象返回到datatables对象的aaData属性，以进行一些自定义格式化。我不能简单地返回字符串数组

这是我的控制器操作，返回一个数组（这是我需要更新的）：

结果对象必须采用以下形式：

[
 { "prop1": "val1",
   "prop2": "val2",
    ......
   "propn": "valn"
 },
 .................


 { "prop1": "val1",
   "prop2": "val2",
    ......
   "propn": "valn"
 },

]

您必须将列表设置为

JSON

字符串，并且您的操作返回类型为

JsonResult

public JsonResult GetData()
{
     var list = filteredResults.Select(temp => new[] { temp.userId.ToString(), temp.userName.ToString(), temp.email.ToString(), temp.phone.ToString(), temp.Postcode.ToString(), temp.Street.ToString(), temp.LastLogin.ToString() }).FirstOrDefault();
     return Json(list, JsonRequestBehavior.AllowGet);
}

您必须调用GetData（）操作并返回

JSON

我实际做的是使用动态对象语法来格式化返回的JSON数组，如下所示：

var result = from u in filteredResults
                     select new 
                     {
                         id = Convert.ToString(u.userId), 
                         userName = u.userName, 
                         roleId = u.roleId.ToString(), 
                         roleName = u.type, 
                         isActive =  u.isActive == true ? "Active" : "Inactive", 
                         firstName = u.firstName, 
                         lastName = u.lastName, 
                         email = u.email, 
                         phone = u.phone,
                         postcode = u.Postcode, 
                         street = u.Street, 
                         company = u.company, 
                         jobId = u.jobId.ToString(),
                         job = u.job, 
                         //countryKey = u.country, 
                         countryName = u.countryName, 
                         city = u.City, 
                         loginsNum = u.LoginsNum.ToString(), 
                         lastLogin = u.LastLogin.ToString()
                     };

        return Json(new
        {
            sEcho = param.sEcho,
            iTotalRecords = result.Count(),
            iTotalDisplayRecords = result.Count(),
            aaData = result
        }, JsonRequestBehavior.AllowGet);

var result = from u in filteredResults
                     select new 
                     {
                         id = Convert.ToString(u.userId), 
                         userName = u.userName, 
                         roleId = u.roleId.ToString(), 
                         roleName = u.type, 
                         isActive =  u.isActive == true ? "Active" : "Inactive", 
                         firstName = u.firstName, 
                         lastName = u.lastName, 
                         email = u.email, 
                         phone = u.phone,
                         postcode = u.Postcode, 
                         street = u.Street, 
                         company = u.company, 
                         jobId = u.jobId.ToString(),
                         job = u.job, 
                         //countryKey = u.country, 
                         countryName = u.countryName, 
                         city = u.City, 
                         loginsNum = u.LoginsNum.ToString(), 
                         lastLogin = u.LastLogin.ToString()
                     };

        return Json(new
        {
            sEcho = param.sEcho,
            iTotalRecords = result.Count(),
            iTotalDisplayRecords = result.Count(),
            aaData = result
        }, JsonRequestBehavior.AllowGet);
