First create an empty asp.net web application known as Ajax, as shown in the following figure.

Among them, the .ashx file is a general processor, so you don't need to know what it is for now. You'll see later.

First of all, let's sort out the functions we want to achieve: the WebForm1 page sends a request to the Handler1 processor every second, the Handler1 returns the data to the WebForm1 page, and the WebForm1 page is partially refreshed through ajax technology.

First, take a look at the main code of Handler1:

Public void ProcessRequest (HttpContext context) {Random rand = new Random (); int num = rand.Next (1m 10); context.Response.Write (num);}

The main purpose of this is to change the ProcessRequest method to the above look to generate a random integer of 1 to 9 and return it to the request page.

Let's take a look at the main code of WebForm1.aspx:

$(document) .ready (function () {function get () {$.ajax ({type: "Post", url: "Handler1.ashx", data: "", success: function (data) {$("# dataShow") .text (data)) });} setInterval (get, 1000);})

Add a line of code to the page:
