netscape.security.PrivilegeManager.enablePrivilege(“UniversalXPConnect”); 时避免出现对话框被称为
嗨，我必须使用 XPCom 在 javascript 中创建、写入、读取本地文件。为此，我在 javascript 的开头添加了以下行。
netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");
但是当上面的脚本执行时，会出现一个对话框，显示“
**Internet security**
A script from "file://" is requesting enhanced abilities
that are UNSAFE and could be used to compromise your machine or data:
Run or install software on your machine
Allow these abilities only if you trust this source
to be free of viruses or malicious programs.

| Deny | | Allow |

但是我不希望出现该对话框。我该如何避免它？”。谢谢。

But when the above script executes, a dialog box appears saying

我认为这是不可能的。如果未经用户明确授权，允许网页获得额外的 JavaScript 权限（在本例中为 XPCOM 的完全访问权限），这将是一个主要的安全问题。
I don't think this is possible. It would be a major security problem to allow a web page to gain extra JavaScript privileges (full access to XPCOM in this case) without an explicit authorization by the user.
