AJAX是什么？

What Is AJAX?

AJAX, short for Asynchronous javascript And XML, isn't a technology but rather a grouping of technologies. AJAX uses a communication technology (typically SOAP and XML) to send and receive an asynchronous request/response to the server, and then leverages presentation technologies ( javascript, DOM, HTML, and CSS) to process the response. Applications using AJAX are legitimate today, because most browsers support the necessary technology. For a more detailed definition of AJAX, visit the AJAX Wikipedia entry.

What does AJAX really mean? It lets you execute a server-side method through a javascript call, without requiring a browser refresh. Think of it as a mini request/response that happens behind the scenes from the user. If you still aren't clear what AJAX is, take a look at two popular examples from Google: Google Suggests and Google Maps. If you are new to AJAX, the responsiveness of those two applications should make your skin tingle slightly.

AJAX是什么？

    AJAX，“异步 javascript和XML”的缩写，说它是一项技术还不如说是一组技术的总和。AJAX利用通信技术（以SOAP和XML为代表）向 服务器发送和接收异步请求/响应，然后再权衡表述技术（ javascript，DOM，HTML，和CSS）来处理响应。现在应用AJAX的应用程序是合 法的，因为多数浏览器都支持这项必要的技术。如果想了解AJAX的详细定义，请访问 AJAX Wikipedia entry。     AJAX到底意味着什么呢？它能让你通过 javascript调用执行服务器端的方法，而不需要浏览器刷新。可以把它想象成发生在用户视线之外的迷你请求 /响应。如果你还不清楚AJAX是什么，看看Google这两个很受欢迎的例子： Google Suggests和 Google Maps。如果你刚刚接触AJAX，这两个应用程序足够让你兴奋的了。 　 文章引用自: http://blog.sina.com.cn/u/53a5c8f50100009s
