Detailed explanation of Ajax principles
Introduction
update time：2018-01-09AJAX is not a new programming language, but a technology for creating better, faster, and more interactive web applications. AJAX allows your JavaScript to communicate directly with the server using JavaScript's XMLHttpRequest object. This object allows your JavaScript to exchange data with the web server without reloading the page. AJAX uses asynchronous data transfer (HTTP requests) between the browser and the web server, which allows a web page to request small pieces of information from the server rather than the entire page. AJAX can make Internet applications smaller, faster, and more user-friendly. AJAX is a browser technology that is independent of web server software. Interested friends can download and take a look
