event auslösten in Javascript Page in TWEBBROWSER

[wschrabi]

Hallo,
also ich fand das hier: http://delphidabbler.com/articles?article=21

Jetzt habe ich eine Site: http://isciencesearch.com/iss
wo als einstiegsseite immer dieses Bild kommt. Anhang1: iss1.jpg

Jetzt möchte ich mit Delphi XE6 u.a. ein event Mouseclick auf diesse rote Seite, wo dann die TEXT Suche kommt starten. Wie kann ich das machen? Wenn ich mal einen Ansatz habe, kann ich dann die Suche weiters mit Delphiroutinen in TWEBBROWSER automatisieren. Doch bin ich mir mit JS nicht ganz klar.

Danke

PS: habe ein kleines DEMO dazugelinkt.
Button 1) und 3) sind zu implementieren. Im SOurce ist es QUESTION1 und QUESTION2

Meinst Du sowas?

Delphi-Quellcode:

procedure ClickImage(wb : TWebBrowser; sImageName : String);
var
  iDoc: IHtmlDocument2;
  i: integer;
  ov: OleVariant;
  iDisp: IDispatch;
  iColl: IHTMLElementCollection;
  InputImage: HTMLInputImage;
begin
  wb.ControlInterface.Document.QueryInterface(IHtmlDocument2, iDoc);
  if not Assigned(iDoc) then begin
    Exit;
  end;
  ov := 'INPUT';
  iDisp := iDoc.all.tags(ov);
  if Assigned(IDisp) then begin
    IDisp.QueryInterface(IHTMLElementCollection, iColl);
    if Assigned(iColl) then begin
      for i := 1 to iColl.Get_length do begin
        iDisp := iColl.item(pred(i), 0);
        iDisp.QueryInterface(HTMLInputImage, InputImage);
        if Assigned(InputImage) then begin
          if InputImage.Name = sImageName then begin
            InputImage.Click;  // klick es
          end;
        end;
      end;
    end;
  end;
end;

(Ein Fundstück von meiner Festplatte, keine Ahnung, wo ich das herhabe.)

SUPER DUFTE!
Es klappt!
Musste nur als sImageName:='btn_StartpageTextsearch_ClientState' eintragen!!!

TAUSEND DANK.
Leider habe ich nicht gelernt wie man mit JAvascript ein event in einem TWEBBROWSER Document auslöst.
egal.

[wschrabi]

noch eine Frage.
ich habe in TWEBBRowser ein iframe göffnet, das bei Beendigung des searchprocesses geschlossen wird.
WIe kann ich in Delphi eine Routine triggern, wenn dieses iframe geschlossen worden ist.

DANKE.
