最小的AJAX类库 microajax
最小的AJAX类库
One of the smallest and easiest AJAX libraries
使用方法：
microAjax("/resource/url", function (res) {
alert (res);
});
alert (res);
});
服务端：
if ($_SERVER['X-Requested-With'] == 'XMLHttpRequest') {
// do something clever
}
// do something clever
}

}
}
this.stateChange = function (object) {
