Ajax文章写完后目录可以自动生成如何生成可参考右边的帮助文档 文章目录 一、Ajax是什么二、使用步骤二、订单管理 提示以下是本篇文章正文内容下面案例可供参考
一、Ajax是什么
AjaxAsynchronous JavaScript and XML是一种用于在不重新加载整个网页的情况下向服务器发送请求并接收响应的技术。它通过 JavaScript 来实现异步通信允许你在网页上动态地加载数据、更新内容和与服务器交互从而提升用户体验。
二、使用步骤
功能介绍 GET\POST以URL和表单的形式向浏览器发送请求并提交页面会刷新。 除此之外也可以基于Ajax向后台发送请求偷偷的发送请求。
依赖jQuery编写ajax代码
