How to turn to page x# with UniPDFFrame

[55143681]

I use UniPDFFrame to open a PDF file,

the file has 5 pages,

how to position to the fourth page?

If you want to use a button to go to a specific page

 

procedure TMainForm.bSetPageClick(Sender: TObject);
begin
    UniSession.AddJS (pdfFrame.JSName + '.iframe.contentWindow.PDFViewerApplication.page=' +  IntToStr(UniSpinPage.Value));
end;

And for c++builder:

UniSession->AddJS(UniPDFFrame1->JSName +".iframe.contentWindow.PDFViewerApplication.page="+IntToStr(UniSpinEdit1->Value));

Sorry but I only use only and always Delphi (for thirty years ...) and I don't know C ++

anyway in Delphi

First Page

UniSession.AddJS (uHTMLPDF.JSName + '.iframe.contentWindow.document.'  + 'getElementById ("firstPage").click()');
 

Last page

UniSession.AddJS (uHTMLPDF.JSName + '.iframe.contentWindow.document.' + 'getElementById ("lastPage").click()');
 

Next page

UniSession.AddJS (uHTMLPDF.JSName + '.iframe.contentWindow.document.' + 'getElementById ("next").click()');
 

Previous Page

UniSession.AddJS (uHTMLPDF.JSName + '.iframe.contentWindow.document.' + 'getElementById ("previous").click()');

i used unigui for a document solution
