Ajax module processing-Analysis of Sina Weibo open source 2

Because Weibo is a system with frequent frontend and backend interactions, Ajax development must also be standardized.

* This system is developed by Asp.net MVC.

First, create two models (one of which is used for paging)

  Public   Class  Jsonmodel {  Public   String Code { Get ; Set  ;}  Public   Object Data { Get ; Set  ;} Public Jsonmodel ( String Code, Object  Data) {code = Code; Data = Data ;}}  Public   Class  Pagerjsonmodel: jsonmodel {  Public   Int Count { Get ; Set ;}  Public Pagerjsonmodel ( String Code, Object Data, Int Count ): Base  (Code, data) {count = Count ;}} 

Code is the processing resultCodeIs an enumerated value. data indicates the actual data to be transmitted.

     Public   Struct  Codestruct {  // Logged On          Public   Static   String Havelogon = "  A00000  "  ;  Public   Static   String Nologin = "  A00001  "  ;  Public  Static   String Nouserexist = "  A00002  "  ;  Public   Static   String Error = "  A00003  "  ;.... 

Then write in the control, for example

PublicJsonresult judgelogin (){If(! Islogin)ReturnNotlogin ();ElseReturnJSON (NewJsonmodel (codestruct. havelogon,New{Name = currentuser. Nickname, id =Currentuser. ID }));}
 

Data will be returned, for example

 
{"Code": "a00000", "data": {"name": "GeniusProgramMember "," ID ": 6 }}
 

Frontend call

$ ( Function  () {$. Ajax ({URL: "/Ajax/judgelogin", Datatype: "JSON" , Cache:  False  , Type: "Post" , Success:  Function  (O ){  If (O. Code = "a00000" ){  //  Todo  Alert (Codelist [O. Code]);
} Else  {  //  Todo  }}); 

At the same time, the front end also has corresponding enumeration data, such:

VaRCodelist ={A00000:"Logged On", A00001:"No Logon", A00002:"User does not exist", A00003:"Error. Please try again later",....
 

So if we want to return some HTML code from the Code rendered by a view and model, I use the following code to convert

 ///   <Summary>         ///  Render the cshtml page as a string  ///   </Summary>          ///   <Param name = "viewname">  Page name  </Param>          ///   <Param name = "model">  Model  </Param>          ///   <Returns> </returns>          Public   String Renderrazorviewtostring ( String Viewname, Object  Model) {viewdata. Model = Model;  Using ( VaR Sw = New  Stringwriter ()){  VaR Viewresult = Viewengines. Engines. findpartialview (controllercontext, viewname );  VaR Viewcontext = New  Viewcontext (controllercontext, viewresult. View, viewdata, tempdata, SW); viewresult. View. Render (viewcontext, SW );  Return  Sw. getstringbuilder (). tostring ();}} 

Then call

 
String data = renderrazorviewtostring ("getcommentshtml", Model );If(!String. isnullorempty (data )){ReturnJSON (NewJsonmodel (codestruct. returnsuccess, data ));}
 

In this way, the returned HTML data can be filled in a container for display.

Continue to work after completion
