javascript - Passing parameter via Ajax -

-

I am working on a project and facing a problem. What is the problem in my code, it can not be detected. Below is my code, do not know why the ajax URL function is not able to obtain the number of ReceivedMessageByIndexNumber.aspx. Thank you.

Javascript: 

  received message (1); Function ReceivedMessage (indexNumber) {$ .ajax ({Type: "Post", URL: "Default.aspx / ReceivedMessageByIndexNumber? IndexNumber =" + Indexing, Content Type: "Application / Jason; Charset = UTF-8", Datatype: " Jason ", success: work (reaction) {var data = response.d; for (var i = 0; i & lt; data; langti; i ++) {warning (data [i]);}}, failure : Function (msg) {$ ('# output'). Text (msg);}}); }   
 Default.aspx:  
  [WebMethod] The message barred index number (int text index) received from the public static bull {string connectionString = @ "data Source = localhost; initial catalog = information system; integrated security = true "; (SqlConnection connection = New SqlConnection (connectionString)) (SqlCommand command = connection.CreateCommand ()) (connection.Open (); Command.CommandText = @ "TextWord SELECT SELECTINDEX = 'TextProperty ='" + textIndex + "' "; Command.ExecuteNonQuery (); Back to true;}}    
 
 
 This is an HTTP POST Method but you are trying to pass the same parameter, it is an HTTP GET. I have never written it, where you can specify the parameters in the URL such as an HTTP GET.  
 Notice I would like to add the Jasonan Data Line below This fills up your post request.  
  Data: '{textIndex:' indexNumber + '"}',   
  Full Function: Message Received Function (IndexNumber) {$ .ajax ({Type: "Post", URL: "Default .aspx / Received MessagebindNumber", Content Type: "Application / Jason; Charset = Utf -8 ", datatype:" Jason ", data: '{textIndex:' 'indexNumber +'"} ', success: function (response) {var data = response D; (Var i = 0; i & lt; data.length; i ++) {warning (data [i]);}}, failure: function (msg) {$ ('# output'). Text (msg);}}); }

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i

I am trying to create Java web framework (and learning), and on the basis of 'Code Generator In the process of making the material view of the database in the process of development, I stumbled into a difficulty, which I do not know how to solve it.
