在 Firefox 中运行 Exe 为什么会出现错误

我在 Firefox 中运行这个，当点击链接时，Firefox 说 NS_ERROR_FILE_UNRECOGNIZED_PATH 而我按照这里的说明进行操作如何使用 Javascript/XPCOM 作为 Windows“运行...”打开 .EXE？

<html>
<head>
<script>
function RunExe(path) {
    try {            
        var ua = navigator.userAgent.toLowerCase();
        if (ua.indexOf("msie") != -1) {
            MyObject = new ActiveXObject("WScript.Shell")
            MyObject.Run(path);
        } else {
            netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");

            var exe = window.Components.classes['@mozilla.org/file/local;1'].createInstance(Components.interfaces.nsILocalFile);
            exe.initWithPath(path);
            var run = window.Components.classes['@mozilla.org/process/util;1'].createInstance(Components.interfaces.nsIProcess);
            run.init(exe);
            var parameters = [""];
            run.run(false, parameters, parameters.length);
        }
    } catch (ex) {
        alert(ex.toString());
    }
}
</script>
</head>
<body>
<a href="#" onclick="javascript:RunExe('C:\Windows\System32\cmd.exe /c start winword.exe');">Open Word</a>
</body>

I run this in Firefox, when clicking on link, Firefox says NS_ERROR_FILE_UNRECOGNIZED_PATH wheread I followed the instruction from here How to open .EXE with Javascript/XPCOM as Windows "Run..."?

<html>
<head>
<script>
function RunExe(path) {
    try {            
        var ua = navigator.userAgent.toLowerCase();
        if (ua.indexOf("msie") != -1) {
            MyObject = new ActiveXObject("WScript.Shell")
            MyObject.Run(path);
        } else {
            netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");

            var exe = window.Components.classes['@mozilla.org/file/local;1'].createInstance(Components.interfaces.nsILocalFile);
            exe.initWithPath(path);
            var run = window.Components.classes['@mozilla.org/process/util;1'].createInstance(Components.interfaces.nsIProcess);
            run.init(exe);
            var parameters = [""];
            run.run(false, parameters, parameters.length);
        }
    } catch (ex) {
        alert(ex.toString());
    }
}
</script>
</head>
<body>
<a href="#" onclick="javascript:RunExe('C:\Windows\System32\cmd.exe /c start winword.exe');">Open Word</a>
</body>

在 JavaScript 文本中，反斜杠表示转义序列的开始。如果您确实想表示反斜杠，则可以使用双反斜杠对其进行转义。

IE
'C:\\Windows\\System32\\cmd.exe /c start winword.exe'

编辑：
从您链接的帖子中对正确答案的评论来看，他的工作方式似乎是：

仅将路径传递给 runexe：
javascript:RunExe('C:\Windows\System32\cmd.exe')

将参数设置为等于命令参数：
varparameters = ["/c start winword.exe"];

所以这在理论上是可行的：

<html>
<head>
<script>
function RunExe(path) {
    try {            
        var ua = navigator.userAgent.toLowerCase();
        if (ua.indexOf("msie") != -1) {
            MyObject = new ActiveXObject("WScript.Shell")
            MyObject.Run(path);
        } else {
            netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");

            var exe = window.Components.classes['@mozilla.org/file/local;1'].createInstance(Components.interfaces.nsILocalFile);
            exe.initWithPath(path);
            var run = window.Components.classes['@mozilla.org/process/util;1'].createInstance(Components.interfaces.nsIProcess);
            run.init(exe);
            var parameters = ["/c start winword.exe"];
            run.run(false, parameters, parameters.length);
        }
    } catch (ex) {
        alert(ex.toString());
    }
}
</script>
</head>
<body>
<a href="#" onclick="javascript:RunExe('C:\\Windows\\System32\\cmd.exe');">Open Word</a>
</body>

尽管显然将参数作为参数传递比像我在这里所做的那样硬编码它们更好（或者将它们作为路径的一部分传递并解析它们）

In javascript literals, a backslash indicates the beginning of an escape sequence. If you actually want to represent a backslash, you can escape it with a double backslash.

ie
'C:\\Windows\\System32\\cmd.exe /c start winword.exe'

http://www.javascriptkit.com/jsref/escapesequence.shtml

EDIT:
From the comments on the correct answer from the post you linked, it looks like the way he got it working was:

only pass the path to runexe:
javascript:RunExe('C:\Windows\System32\cmd.exe')

set the params equal to the command args:
var parameters = ["/c start winword.exe"];

So this would work theoretically:

<html>
<head>
<script>
function RunExe(path) {
    try {            
        var ua = navigator.userAgent.toLowerCase();
        if (ua.indexOf("msie") != -1) {
            MyObject = new ActiveXObject("WScript.Shell")
            MyObject.Run(path);
        } else {
            netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");

            var exe = window.Components.classes['@mozilla.org/file/local;1'].createInstance(Components.interfaces.nsILocalFile);
            exe.initWithPath(path);
            var run = window.Components.classes['@mozilla.org/process/util;1'].createInstance(Components.interfaces.nsIProcess);
            run.init(exe);
            var parameters = ["/c start winword.exe"];
            run.run(false, parameters, parameters.length);
        }
    } catch (ex) {
        alert(ex.toString());
    }
}
</script>
</head>
<body>
<a href="#" onclick="javascript:RunExe('C:\\Windows\\System32\\cmd.exe');">Open Word</a>
</body>

Although clearly it would be better to pass in the params as an argument than hardcode them as I've done here (or pass them in as part of the path and parse them out)
