Hello.

1. If you want to change the caption of the Form1 you can use this line of
code:
  <tag oncommand="window.title=\"New Caption\""/>

  2. If you need to get access to Delphi object from JavaScript you need
chooise the
  other way.
  To do it you must create a IMyForm1.idl interface. Build it by xpidl2pas
compiler.
  Implement skeleton for interface IMyForm1 as wrapper for native Delphi
Form1.

  TMyForm1 = class(TnsSupports, IMyForm1)
    function Get_Caption : nsString;
    procedure Set_Caption(const Value : nsString);
    constructor Create(AOwner : TForm1);
  end;

  Implement the factory to create instance of object. Don't forget registr
one in GRE.

  TMyFormFactory = class(TnsSupports, nsIFactory)
    function CreateInstance(aOuter : nsISupportsH; const iid : TGUID; var
_result : Pointer): HRESULT;
end;

  function TMyFormFactory.CreateInstance(aOuter : nsISupportsH; const iid :
TGUID; var _result : Pointer): HRESULT;
  begin
    _result := TnsSupports.Get_NSInterface(TMyForm1.Create(Form1),
IMyForm1);
  end;

  For now you can get access to Form1 from JavaScript.

  function deplhiAccess()
  {
    Form1 = Components.classes[COMPONENT_MYFORM1_KEY].createInstance();
    Form1 = Form1.QueryInterface(Components.Interfaces.IMyForm1);
    Form1.Caption = "New Caption";
  }

  <tag oncommand="deplhiAccess()"/>

  Don't try to build it directly. This is only idea and must be going to
debug!
