JavaScript: Read files in folder

EDIT: I'm trying to read all the files in a specific folder and list the files in there, not read the content of a specific file. I just tried to simply create an FileSystemObject and it doesn't do anything either. I show an alert (which pops up) beforfe making the FileSystemObject, and one after it (which isn't shown). So the problem is in simply creating the object.

Original:

I am trying to read all the files in a folder by using JavaScript.

It is a local HTML file, and it will not be on a server, so I can't use PHP I guess.

Now I'm trying to read all the files in a specific given folder, but it doesn't do anything on the point I make a FileSystemObject

Here is the code I use, The alert shows until 2, then it stops.

    alert('1');
    var myObject, afolder, date;
    alert('2');
    myObject = new ActiveXObject("Scripting.FileSystemObject");
    alert('3');
    afolder = myObject.GetFolder("c:\\tmp");
    alert('4');
    date = afolder.DateLastAccessed;
    alert("The folder"+name+" is a temporary folder.");

Am I doing this the right way?

Thanks!
