我收到了这个错误：
DataTables warning (table id = 'example'): DataTables warning: JSON data from server could not be parsed. This is caused by a JSON formatting error.
在下面的代码中。我想为server_processing.php的此代码发送任何参数，并使用$_GET创建SQL命令。
此代码显示此结果
{"sEcho":0,"iTotalRecords":"1","iTotalDisplayRecords":"112","aaData":[["\u0633\u06cc\u062f \u0645\u062d\u0645\u062f \u0639\u0644\u06cc","\u0645\u062d\u0633\u0646\u06cc","sma_mohseni","2012\/11\/10","50.48.6.52"],["\u0633\u06cc\u062f \u0645\u062d\u0645\u062f \u0639\u0644\u06cc","\u0645\u062d\u0633\u0646\u06cc","sma_mohseni","2012\/11\/10","50.48.6.52"]]}
在www.jsonformatter.curiousconcept.com的json检查结果中警告我json结果是有效的

当您的服务器端脚本发生脚本错误时，这是典型的答案类型。尝试使用chrome web检查器或firebug以及网络选项卡来检查返回的结果。
