Even on IE, if you do this from a page served via HTTP, you're going to hit security blocks. — T.J. Crowder, Jun 19 '12 at 13:10

ActiveXObject is available only on IE browser. So every other useragent will throw an error

On modern browser you could use instead File API or File writer API (currently implemented only on Chrome)

File API is read only, so you can't. – Quentin Jun 19 '12 at 13:13

ActiveXObject is non-standard and only supported by Internet Explorer on Windows.

There is no native cross browser way to write to the file system without using plugins, even the draft File API gives read only access.

If you want to work cross platform, then you need to look at such things as signed Java applets (keeping in mind that that will only work on platforms for which the Java runtime is available).

A web app can request access to a sandboxed file system by calling window.requestFileSystem(). Works in Chrome.

window.requestFileSystem = window.requestFileSystem || window.webkitRequestFileSystem;
var fs = null;

window.requestFileSystem(window.TEMPORARY, 1024 * 1024, function (filesystem) {
    fs = filesystem;
}, errorHandler);

fs.root.getFile('Hello.txt', {
    create: true
}, null, errorHandler);

function errorHandler(e) {
  var msg = '';

  switch (e.code) {
    case FileError.QUOTA_EXCEEDED_ERR:
      msg = 'QUOTA_EXCEEDED_ERR';
      break;
    case FileError.NOT_FOUND_ERR:
      msg = 'NOT_FOUND_ERR';
      break;
    case FileError.SECURITY_ERR:
      msg = 'SECURITY_ERR';
      break;
    case FileError.INVALID_MODIFICATION_ERR:
      msg = 'INVALID_MODIFICATION_ERR';
      break;
    case FileError.INVALID_STATE_ERR:
      msg = 'INVALID_STATE_ERR';
      break;
    default:
      msg = 'Unknown Error';
      break;
  };

  console.log('Error: ' + msg);
}
