基本上，我使用AJAX进行服务器和客户端通信。因此，当最终用户在register.htm完成信息输入后，它将使用XMLHttpsRequest.open进入javascript文件register.php以更新XML上的数据。但它不会更新我的XML数据。

任何建议都将不胜感激。

saveXML

需要一个文件名

如果指定，函数将数据写入文件而不是返回它

saveXML

是

asXML

的别名，我也尝试过。但我的xml文件也没有更新。P/S$xmlFile=“customer.xml”您的代码工作正常-xml更新部分正常，我已经测试过了。因此，漏洞在别处。缺少写入权限？奇怪。我应该在这里发布整个代码吗@@
