The example in this article describes the way jquery uses $.ajax for asynchronous refreshes. Share to everyone for your reference, specific as follows:

With the recent function of using jquery to read data asynchronously, jquery provides many built-in asynchronous read functions to demonstrate the most common $.ajax usage

Enter a content in the Client text box, and then return the time on the server side

Client code

<%@ Page language= "C #" autoeventwireup= "true" codefile= "Default7.aspx.cs" inherits= "Default7"%> <! DOCTYPE HTML PUBLIC "-//W3C//DTD XHTML 1.0 transitional//en" "Http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd ">  

Server-side code

<%@ WebHandler language= "C #" class= "ContentHandler"%> 
using System; 
Using System.Web; 
public class Contenthandler:ihttphandler {public 
 void ProcessRequest (HttpContext context) { 
  string output = "" ; 
  String name = Context. request.params["name"]; 
  Output = Getjsondata (name); 
  Context. Response.ContentType = "Text/plain"; 
  Context. Response.Write (output); 
 } 
 public bool IsReusable {get 
  {return 
   false; 
  } 
 } 
 public string Getjsondata (String aa) 
 { 
  string result = "{name:/" "+aa+"/", dt:/" "+datetime.now.tostring () +"/ "}"; 
  return result;
