    AJAX处理流程

    JavaScript程序读取XML并直接在HTML中显示的例子.
    1. //判断不同浏览器,并创建new XMLHttpRequest赋值给http_request
    2. // 既然是非同步的进行方式,在open()以及send()之前,我们"必须"先设定一些事件处理的函数來处理如"已经取得资料"的事件.
    3. http_request.open() 以及 http_request.send()
    4. http_request.status == 200 和 http_request.readyState == 4 ,表示数据处理成功
    5. 执行输出等...document.write

    专业的流程描述

    1. 初始化对象,并发出XMLHttpRequest请求
    2. 指定响应处理函数
    3. 发出HTTP请求
    4. 处理服务器返回的信息
