问题描述
我试图
1）使用javascript作为对象加载xml文件，比如 note.xml
2）然后将对象保存到新的xml文件，例如 note_new.xml
2) then save the object to a new xml file, say note_new.xml
我做了1）但失败了2）
I did 1) but failed 2)
我试图用方法save（）做2）。我失败后，我检查了ms网站，他们说不支持save（）....
I tried to use method save() to do 2). After my failure, I checked ms site and they said save() is not supported....
有人可以告诉我如何进行保存吗？

var xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async=false;

}else{
alert("i am not withActiveXObject!");
xhttp=new XMLHttpRequest();
xhttp.open("GET","note.xml",false);

更新：
似乎这是相关的安全问题。我向那些经验丰富的程序员道歉，因为这似乎是一个新手问题。
seems this is related to security issue. I appologize to those experienced programmers for my putting this question in a rush because it seems a newbie question.
推荐答案
您的问题是：javaScript没有输入/输出（ I / O ）API，因为它是客户端脚本语言，因此无法通过服务器访问文件系统。您需要使用服务器端脚本语言将数据保存到服务器。客户端可能存在解决问题的黑客攻击，但它们可能是无法解决的，也可能是其他问题。 （顺便说一下：什么api是保存方法成员？你做到了吗？）
Your problem is: javaScript does not have an input/output (I/O) API as it is a client-side scripting language and consequently has no access to the file system via the server. You would need to use a server-side scripting language to save data to a server. There may be hacks to solve your problem client-side, but they are probably either unsave or otherwise buggy. (btw: what api is the save method member of? Did you make that up?)
你能做什么do将数据临时保存到任何DOM元素（例如窗口或javaScript）对象。然而，无法永久地进行这些更改。
What you can do is save data temporarily to any DOM element (e.g. window, or a javaScript) object. There is however no way to make these changes permanent.
在您的情况下，查看 PHP 脚本可能是最好的方式。
In your case, looking in to PHP scripting might be the best way to go.
