Hiding buttoms in UniguiPDFFrame

[angman]

Hi,  I put this

procedure TFStampeSLP.unpdfrmDocFrameLoaded(Sender: TObject);
begin
  UniSession.AddJS(unpdfrmDoc.JSName + '.iframe.contentWindow.document.' +
    'getElementById ("download").style.display = "none"');
  UniSession.AddJS(unpdfrmDoc.JSName + '.iframe.contentWindow.document.' +
    'getElementById ("secondaryDownload").style.display = "none"');

      UniSession.AddJS(unpdfrmDoc.JSName + '.iframe.contentWindow.document.' +
    'getElementById ("print").style.display = "none"');
  UniSession.AddJS(unpdfrmDoc.JSName + '.iframe.contentWindow.document.' +
    'getElementById ("secondaryPrint").style.display = "none"');

end;

It is working, but when the application run, got this ajax error:

O1C8.iframe.contentWindow.document.getElementById ("download").style.display = "none";O1C8.iframe.contentWindow.document.getElementById ("secondaryDownload").style.display = "none";O1C8.iframe.contentWindow.document.getElementById ("print").style.display = "none";O1C8.iframe.contentWindow.document.getElementById ("secondaryPrint").style.display = "none";

can you suggest a solution?

procedure TfDataEntry.unpdfrmDocLoaded(Sender: TObject);
begin

if unpdfrmDoc.PDFURL > '' then begin

      // download button
      UniSession.AddJS (unpdfrmDoc.JSName + '.iframe.contentWindow.document.'
          + 'getElementById ("download").style.display = "none"');
      UniSession.AddJS (unpdfrmDoc.JSName + '.iframe.contentWindow.document.'
          + 'getElementById ("secondaryDownload").style.display = "none"');

end;

end;
