JQuery Ajax dynamically generates Table tables
The implementation process is as follows: the front desk calls the general handler (Handler) through jquery's ajax to obtain the information that the table needs to display, and then converts it into json format and returns it to the front desk. After the front desk obtains the data, it loops to build the rows of the table, and finally to append rows to the table. Friends who are interested, let’s take a look
Preface:
The approximate function of this example is to call the general handler (Handler) through JQuery’s Ajax at the front desk to obtain the table that needs to be displayed. The information is then converted into json format and returned to the front desk. After the front desk obtains the data, it loops to construct the rows of the table. It is best to append the rows to the table.
Objectives:
a Be familiar with the use of simple JQuery Ajax
b Understand how to construct basic Json format data (Json can also be constructed through Third party dll)
c Get familiar with the basic usage of handler
1 Simple rendering
2 Front Desk Code

<%@ WebHandler Language="C#" Class="TestHandler" %> using System; using System.Web; using System.Collections.Generic; using System.Text; using DataDAL; using DataEnity; public class TestHandler : IHttpHandler { HttpRequest Request; HttpResponse Response; public void ProcessRequest (HttpContext context) { //不让浏览器缓存 context.Response.Buffer = true; context.Response.ExpiresAbsolute = DateTime.Now.AddDays(-1); context.Response.AddHeader("pragma", "no-cache"); context.Response.AddHeader("cache-control", ""); context.Response.CacheControl = "no-cache"; context.Response.ContentType = "text/plain"; Request = context.Request; Response = context.Response; string method = Request["Method"].ToString(); System.Reflection.MethodInfo methodInfo = this.GetType().GetMethod(method); methodInfo.Invoke(this, null); } public void GetModuleInfo() { StringBuilder sb = new StringBuilder(); string jsonData = string.Empty; List<Module> lsModule = ModuleDAL.GetModuleList(); sb.Append("{\"Module\":["); for (int i = 0; i < lsModule.Count; i++) { jsonData = "{\"ModuleNum\":" + "\"" + lsModule[i].ModuleNum + "\"" + ",\"ModuleName\":" + "\"" + lsModule[i].ModuleName + "\"" + ",\"ModuleDes\":" + "\"" + lsModule[i].ModuleDes + "\"" + "},"; sb.Append(jsonData); } if (lsModule.Count > 0) sb = sb.Remove(sb.Length - 1, 1); sb.Append("]}"); Response.Write(sb); } public bool IsReusable { get { return false; } } }
The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.

Using Ajax to obtain variables from PHP methods is a common scenario in web development. Through Ajax, the page can be dynamically obtained without refreshing the data. In this article, we will introduce how to use Ajax to get variables from PHP methods, and provide specific code examples. First, we need to write a PHP file to handle the Ajax request and return the required variables. Here is sample code for a simple PHP file getData.php:

Title: jQuery Tips: Quickly modify the text of all a tags on the page In web development, we often need to modify and operate elements on the page. When using jQuery, sometimes you need to modify the text content of all a tags in the page at once, which can save time and energy.

Title: Use jQuery to modify the text content of all a tags. jQuery is a popular JavaScript library that is widely used to handle DOM operations. In web development, we often encounter the need to modify the text content of the link tag (a tag) on the page. This article will explain how to use jQuery to achieve this goal, and provide specific code examples. First, we need to introduce the jQuery library into the page. Add the following code in the HTML file:

Ajax (Asynchronous JavaScript and XML) allows adding dynamic content without reloading the page. Using PHP and Ajax, you can dynamically load a product list: HTML creates a page with a container element, and the Ajax request adds the data to that element after loading it. JavaScript uses Ajax to send a request to the server through XMLHttpRequest to obtain product data in JSON format from the server. PHP uses MySQL to query product data from the database and encode it into JSON format. JavaScript parses the JSON data and displays it in the page container. Clicking the button triggers an Ajax request to load the product list.

How to tell if a jQuery element has a specific attribute? When using jQuery to operate DOM elements, you often encounter situations where you need to determine whether an element has a specific attribute. In this case, we can easily implement this function with the help of the methods provided by jQuery. The following will introduce two commonly used methods to determine whether a jQuery element has specific attributes, and attach specific code examples. Method 1: Use the attr() method and typeof operator // to determine whether the element has a specific attribute

jQuery is a popular JavaScript library that is widely used to handle DOM manipulation and event handling in web pages. In jQuery, the eq() method is used to select elements at a specified index position. The specific usage and application scenarios are as follows. In jQuery, the eq() method selects the element at a specified index position. Index positions start counting from 0, i.e. the index of the first element is 0, the index of the second element is 1, and so on. The syntax of the eq() method is as follows: $("s
