**课程名称：** AJAX JavaScript XHR and Fetch **课程概述：** 本课程将介绍如何使用 AJAX（Asynchronous JavaScript And XML）技术，让你能够创建更具响应性和动态性的网页。AJAX 允许网页在用户需要时才请求和显示小块数据（如 HTML、XML、JSON 或纯文本），而无需重新加载整个页面。通过 XMLHttpRequest 和 Fetch API 等接口，你可以直接在网页中发起 HTTP 请求，获取特定资源。 **课程内容亮点：** * **AJAX 的核心原理：** 理解 AJAX 如何工作，以及它与传统网页加载模式的区别。 * **XMLHttpRequest (XHR) 和 Fetch API：** 学习如何使用这两种主要的 AJAX API 发送请求、接收响应，并处理返回的数据。 * **JavaScript 的关键作用：** 掌握如何使用 JavaScript 连接网页内容与服务器数据，实现数据在前后端的交互。 * **实践项目：** 动手构建一个随机用户加载器，从外部文件加载内容，连接 Web API 获取数据，以及获取随机笑话并显示在网页上。 * **表单数据提交：** 学习如何使用 Fetch API 将表单数据发布到服务器。 * **实用的本地开发环境搭建：** 了解如何设置本地服务器。 * **丰富的学习资源：** 课程提供 AJAX 源代码，并在问答区提供友好的技术支持，由经验丰富的讲师解答你的疑问。 **为什么选择这门课程？** 如果你想提升网页的用户体验，让你的网站更加流畅和现代化，那么这门课程将是你的理想选择。通过学习 AJAX，你将迈出构建令人惊叹的 Web 应用的第一步！
Welcome to our introductory course for using AJAX - Asynchronous JavaScript And XML AJAX allows web pages to request small chunks of data (such as HTML, XML, JSON, or plain text) and display them only when needed. This is achieved by using APIs like XMLHttpRequest or Fetch API. These technologies allow web pages to directly handle making HTTP requests for specific resources Typically when a user goes to a website the user has to wait for the server to respond with the data. This is not the case as with AJAX we have the option to load the data when the user is already on the page making the user really happy. This course covers making AJAX requests using the XMLHttpRequest as well as the newer fetch. Use JavaScript to send requests, receive response content and use the response data to output into the html. JavaScript is at the center of it all connecting the web page content to the server data and doing all the work in between. Course Covers How to setup a localhostWhat Fetch and XHR are and how they workHow to load an external files into the JavaScriptHow to connect to web apis and load dataUsing JavaScript to read response content and make use of itExercise to build a random user loaderUsing AJAX to get a txt file contentExercise Getting Random Jokes to output on a websiteUsing FetchExercise Posting form data to a server using FetchPractice AJAX Source Code is included Friendly support in the Q & A section Taught by an instructor with many years real world web development experience ready to answer your questions and help you learn AJAX.
