似乎这与安全问题有关。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。

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?)

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是保存方法的成员？你做到了吗？）

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.

您可以做的是将数据临时保存到任何DOM元素（例如窗口或javaScript）对象。然而，没有办法使这些变化永久化。

In your case, looking in to PHP scripting might be the best way to go.

在您的情况下，查看PHP脚本可能是最好的方法。
