类名:AJAX
/*类名:AJAX
创建方法:var ajaxobj=new AJAX;,如果创建失败则返回false
属性:method - 请求方法,字符串,POST或者GET,默认为POST
url - 请求URL,字符串,默认为空
async - 是否异步,true为异步,false为同步,默认为true
content - 请求的内容,如果请求方法为POST需要设定此属性,默认为空
backtext - 默认true当backtext=true时返回XMLHttp.responseText为false时返回XMLHttp.responseXML
gettext - 返回值
callback - 回调函数,即返回响应内容时调用的函数,默认为直接返回,回调函数有一个参数为XMLHttpRequest对象,即定义回调函数时要这样:function mycallback(xmlobj)
方法:send() - 发送请求,无参数
