Jquery Ajax asynchronously acquires data

Because it is part of the project, I am only part of it.CodeFor details, refer:

<Table width = "  100%  " Border = "  0  " Cellspacing = "  0  " Cellpadding = "  5  " > <Tr> <TD id = " Latestnews  " Height = "  330  " Align = "  Center  " Valign = "  Top  "   Class = "  Font14  " Style = " Border: #7baed9 solid 1px; Border-top: none; padding: 10px; "  > </TD> </tr> </table>

It is mainly used to obtain data through jquery Ajax and display it in the ID number "latestnews" TD. The following is the Ajax code:

<SCRIPT type = "  Text/JavaScript  " > $ (Function () {$. Ajax ({type:  "  Post  " , URL:  "  Ceo2012/latestnews. ashx  "  , Contenttype:  "  APP/JSON; charset = UTF-8  "  , Datatype:  "  JSON  "  , Success: function (data) {$ (  "  # Latestnews "  ).Html (data) ;}, error: function (error) {$ (  "  # Latestnews  " Pai.html ( "  No information has been published!  "  );}});}); </SCRIPT>

Below is a general method for processing latestnews. ashx in the ceo2012 Folder:

 ///   <Summary>          ///  Latest media reports ///   </Summary>          ///   <Param name = "context"> </param>          Public   Void  Processrequest (httpcontext context) {context. response. contenttype = "  Text/plain  "  ; JavascriptserializerJavascriptSerializer = New Javascriptserializer (); string strhtml = "  <Ul style = 'text-align: left'>  "  ; Datatable dt = New  Datatable (); newsrule = New  Newsrule (); dt = Newsrule. getnewsbytid ( 640 , 15 , "  Sortid DESC "  );  If (Dt. Rows. Count = 0  ) {Context. response. Write (  "  No information has been published!  "  );  Return  ;}  For ( Int I = 0 ; I <DT. Rows. Count; I ++){  If (! String. isnullorempty (Dt. Rows [I] [ "  Aurl  "  ]. Tostring () {strhtml + = "  <Li> <a href ='  " + Dt. Rows [I] [ "  Aurl  " ]. Tostring () + "  'Title =' " + Dt. Rows [I] [ "  Title  " ]. Tostring () + "  'Target = \ "_ blank \">  " + Dt. Rows [I] [ "  Title  " ]. Tostring () + "  </A>  "  ;}  Else {Strhtml + = "  <Li> <a href = \ "http://www.sino-manager.com/  " + Returndate (datetime. parse (Dt. Rows [I] [ "  Pubtime  " ]. Tostring (). tow.datestring () + "  _  " + Dt. Rows [I] [ "  Postid  " ]. Tostring () +"  . Html \ "Title = \"  " + Dt. Rows [I] [ "  Title  " ]. Tostring () + "  \ "Target = \" _ blank \ ">  " + Dt. Rows [I] [ "  Title  " ]. Tostring () + "  </A> </LI>  " ;} Strhtml + = "  </Ul>  "  ; String content = Javascriptserializer. serialize (strhtml); context. response. Write (content );
