  Params: TStrings);

Use TUniTimer

 

procedure TMainForm.UniFormAjaxEvent(Sender: TComponent; EventName: string;
  Params: TStrings);
begin
  if EventName='afterrender' then
  begin
  UniTimer1.Enabled := True;
  end;
end;

procedure TMainForm.UniTimer1EventHandler(Sender: TComponent;  EventName: string; Params: TStrings);
begin
  UniSession.SendResponse('var ael=document.getElementById("audio2");ael.load();ael.play()');
end;

 

Timer event not fiered
