attempting with nslEnvironment:
与nslEnvironment尝试:
var env = Components.classes["@mozilla.org/process/environment;1"].getService(Components.interfaces.nsIEnvironment);
dump("bash=" + env.exists("BASH") + '\n');
dump("bash=" + env.exists("$BASH") + '\n');
the output was:
输出结果是:
bash=false
bash=false
as you imagine, it should output "/bin/bash" as it does in the terminal. I also tried using get
to see if it was just the exists
method wrong, but it returned empty.
正如您想象的,它应该输出“/bin/bash”,就像在终端中那样。我还尝试使用get查看它是否只是exist方法出错,但它返回为空。
What can be wrong here?
这里有什么问题吗?

Have a look at Setting an environment variable in javascript (which you happened to edit, randomly!).
看看如何在javascript中设置一个环境变量(您碰巧编辑了它,是随机的!)
I very much doubt you'll be able to read these variables from a browser environment though.
我非常怀疑您是否能够从浏览器环境中读取这些变量。

编辑:
var oShell = WScript.CreateObject("WScript.Shell");
var oSysEnv = oShell.Environment("SYSTEM");
WScript.Echo (oSysEnv("PATH"));
perhaps?
也许?
