时间:2020-05-11 人气:0

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
