evaluate system command or python script in firefox browser using javascript

May be duplicate.

I would like to write javascript which can execute linux command in firefox (seems to be impossible but asking w开发者_运维百科ith hope)

from googling, found that it is possible for IE through "ActiveXObject".

here is sample code:

<SCRIPT type="text/javascript" LANGUAGE="JavaScript">
  function executeCommands(inputparms)
   {
  // Instantiate the Shell object and invoke 
   its execute method.

    var oShell = new ActiveXObject("Shell.Application");

    var commandtoRun = "C:\\Winnt\\Notepad.exe";
    if (inputparms != "")
     {
      var commandParms = document.Form1.filename.value;
     }

 // Invoke the execute method.  
     oShell.ShellExecute(commandtoRun, commandParms, 
      "", "open", "1");
  }
</SCRIPT>

So, Is there any equivalent of ActiveXObject in javascript for mozilla apps? I'm quite new to javascript so please, correct mistakes if any.

Thanks!


In a Firefox add-on you can use nsIProcess. Something along these lines:

var file = Components.classes["@mozilla.org/file/local;1"]
                     .createInstance(Components.interfaces.nsILocalFile);
file.initWithPath("C:\\Winnt\\Notepad.exe");
var process = Components.classes["@mozilla.org/process/util;1"]
              .createInstance(Components.interfaces.nsIProcess);
process.init(file);
process.runAsync(["c:\\file.txt"]);

This API is only accessible to privileged code of course.


No, it's not possible to run arbitrary, native commands on the client's machine.
