推荐答案

Ajax的关键是XmlHTTPRequest对象，它可以帮助您与服务器通信并接收文本响应.您可以使用JavaScript DOM将页面中的相关元素替换为服务器返回的新文本.

任何支持异步处理的浏览器都使用XMLHttp对象，如果不支持XMLHttp，则AJAX将不起作用.
IE4和更高版本中提供了此功能

Any browser to support Asynchronus processing uses XMLHttp object, if XMLHttp is not supported, then AJAX will not work.
This is available from IE4 and higher versions
