Can you use JavaScript to read and write to a file?

Now I was searching high and low for the answer to this question. The big answer that I got was, JavaScript cannot read or write to files. However, it is possible to do this using ActiveX embedded into your JavaScript. The following is the code to do this.



//-------------------------------------------------------

function WriteToFile()

{

    var filename = "data.txt";

    var fso = new ActiveXObject("Scripting.FileSystemObject");

    if (fso.FileExists(filename))

    {

        var a, ForAppending, file;

        ForAppending = 8;

        file = fso.OpenTextFile(filename, ForAppending, false);

        file.WriteLine(name);

        file.WriteLine(password);

    }

    else

    {

        var file = fso.CreateTextFile(filename, true);

        file.WriteLine(name);

        file.WriteLine(password);

    }

    file.Close();

}

//-------------------------------------------------------

function ReadFromFile()

{

    var fso, a, ForReading;

    ForReading = 1;

    fso = new ActiveXObject("Scripting.FileSystemObject");

    file = fso.OpenTextFile(filename, ForReading, false);

    var name = file.readline();

    var password = file.readline();

    file.Close();

}

//-------------------------------------------------------



In IE you can use the FileSystemObject to read and write to/from files.
