我正在使用mvc格式的JQuery数据表。使用条件绑定JQuery数据表。但是我不知道如何去解决这个问题,显示错误信息。我需要显示错误警报消息服务器端是客户端。我的示例代码:如何在JQuery数据表中发送错误消息警报

public ActionResult Action(string EmpNo) 
     { 
      if (condition) 
      { 
       // data table passing 
      } 
      else 
      { 
       //here how to show the error message client side or server side 
      } 
     }

您可以返回JavascriptResult。 JavaScriptResult

return Javascript("yourJS COde"); 

一些这样的事

public ActionResult TestJavaScript() { 
    string s = "$('#divResultText').html('JavaScript Passed');"; 
    return JavaScript(s); 
}

我们在客户端使用jauery数据表我们只需要发送数据表格中的错误 – user279stack 2013-03-14 05:16:56

你应该任意对象返回JsonResult(或实物,如果你已经创建了一个)匹配的数据表的预期收益签名。喜欢的东西:

var result = // do something, get a list of stuff etc 

return new JsonResult { 
    // `Data` is the thing that turns into your json response 
    Data = new { 
     error = result.Success ? "" : result.Message, 
     fieldErrors = new bool[0], // just to fake an empty array 
     data = new bool[0], 
     aaData = result.Success ? result.Items.Select(o => new { 
      //use arbitrary column names if you've specified them in config with `aoColumns` and `mDataProp`, see comment below 
      OrderID = o.ID, 
      ChannelID = o.Partner, 
      ReferenceKey = o.PartnerReferenceKey, 
      o.CustomerEmail, 
      Status = o.Status.ToString(), 
      Value = o.Total, 
      CreatedOn = o.CreatedOn.ToString("yyyy-MM-dd HH:mm:ss"), // provide in interpretable format 
     }) : (object) new bool[0], // must return an empty list in order for it to understand errors 
     iTotalRecords = result.TotalCount, 
     iTotalDisplayRecords = result.TotalCount, // should be different if filtering 
     sEcho // this is provided by the request, not sure what it means... 
    } 
}; 

对于从Ajax响应自定义列名,你要检讨:
