xajax无刷新上传实例
http://www.corange.cn/archives/2008/10/2080.html
主要的xajax结合php上传文件和保存数据的函数集中存放在 ./admin/includes/function.xajax.php 里面
在language.php文件载入并初始化xajax上传扩展
require_once(ROOT_PATH . '/includes/xajax/xajax.inc.php');
require_once(ROOT_PATH . '/admin/includes/function.xajax.php');
require_once(ROOT_PATH . '/includes/xajax/xajaxExtend.php');
//$xajax = new xajax();
$xajax = new xajaxExtend;
//$xajax->debugOn();
$xajax->registerFunction("ShowCreateLanguage");
$xajax->registerFunction("CreateLanguage");
$xajax->registerFunction("DeleteLanguage");
$xajax->registerFunction("ModifyLanguage");
$xajax->registerFunction("UpdateLanguage");
$xajax->processRequests();

在调用扩展上传，其中CreateLanguage是php中处理上传的函数 f1是表单的id
<script language="Javascript">
function checkForm() {
return xajax.upload('CreateLanguage','f1');
}
function updateForm() {
return xajax.upload('UpdateLanguage','f2');
}
</script>
