如何通过 Javascript 检测 Internet Explorer 的临时 Internet 文件位置？

我正在尝试将 Firefox 扩展移植到 IE。我需要的功能之一是能够写入浏览器的临时文件。在 Firefox 中，这可以通过以下代码轻松完成：

//Create file to store data transferred to desktop app
var file = Components.classes["@mozilla.org/file/directory_service;1"].
               getService(Components.interfaces.nsIProperties).
               get("TmpD", Components.interfaces.nsIFile);
    file.append("MyExtTempFile.txt");
    file.createUnique(Components.interfaces.nsIFile.NORMAL_FILE_TYPE, 0666);
    // do whatever you need to the created file

这种方法比硬编码路径更可取，因为它可能会在不同版本的 Windows/IE 上发生变化。

我想出了如何在 IE 中创建和写入文件：

var fso  = new ActiveXObject("Scripting.FileSystemObject");
var fh = fso.CreateTextFile("C:\\Users\\Administrator\\Desktop\\MyExtTempFile.txt", true);
fh.WriteLine("Some text goes here...");
fh.Close();

现在我只是想知道如何自动检测 IE 的临时文件位置？

I am attempting to port an Firefox extension to IE. One of the features I need to have is the ability to write to the Temp Files of the browser. In Firefox this was easily done by the following code:

//Create file to store data transferred to desktop app
var file = Components.classes["@mozilla.org/file/directory_service;1"].
               getService(Components.interfaces.nsIProperties).
               get("TmpD", Components.interfaces.nsIFile);
    file.append("MyExtTempFile.txt");
    file.createUnique(Components.interfaces.nsIFile.NORMAL_FILE_TYPE, 0666);
    // do whatever you need to the created file

This method was preferable rather than hard coding a path in because it could change on different versions of Windows / IE.

I figured out how to create and write to a file in IE by:

var fso  = new ActiveXObject("Scripting.FileSystemObject");
var fh = fso.CreateTextFile("C:\\Users\\Administrator\\Desktop\\MyExtTempFile.txt", true);
fh.WriteLine("Some text goes here...");
fh.Close();

Now I am just wondering how to automatically detect the temp file location for IE?
