Error with pageNum

[HeikoH22]

Hello,

I had updated from V 1.x up to V2.0 (Build 42.2).
Now there is a problem with reading the page numbers correctly. There is only “0” displayed.
What can we do to solve this problem?

Code: Select all

    'Alle Bookmarks werden ausgelesen
    jsCode = "function DumpBookmark(bkm, nLevel)"
    jsCode = jsCode & "{"
    jsCode = jsCode & "var s = '';"
    jsCode = jsCode & "for (var i = 0; i < nLevel; i++) s += ' ';"
    jsCode = jsCode & "s += '+-';"
    jsCode = jsCode & "bkm.execute(this.gotoNamedDest(bkm.name));"
    jsCode = jsCode & "s += bkm.name;"
    jsCode = jsCode & "s += '=====' + this.pageNum;"
    jsCode = jsCode & "s += '\n';"
    jsCode = jsCode & "if (bkm.children != null)"
    jsCode = jsCode & "{"
    jsCode = jsCode & "for (var i = 0; i < bkm.children.length; i++)"
    jsCode = jsCode & "s += DumpBookmark(bkm.children[i], nLevel + 1);"
    jsCode = jsCode & "}"
    jsCode = jsCode & "return s;"
    jsCode = jsCode & "}"
    jsCode = jsCode & "DumpBookmark(this.bookmarkRoot, 0);"

Best regards

Hello Heiko,

I think it's because of the gotoNamedDest function.
Please see this one (from the Adobe JS API reference), it worked for me, just the text output is in the console:

Code: Select all

function DumpBookmark(bkm, nLevel)
{
  var s = "";
  for (var i = 0; i < nLevel; i++) s += " ";
  console.println(s + "+-" + bkm.name);
  if (bkm.children != null)
  for (var i = 0; i < bkm.children.length; i++) 
  DumpBookmark(bkm.children[i], nLevel + 1); 
} 
console.clear(); console.show();
console.println("Dumping all bookmarks in the document.");

DumpBookmark(this.bookmarkRoot, 0);

Best Regards,
Stefan

Hello,

the problem persists.
I tried to solve the problem by presenting it in different discussion fora, unfortunately without success.
Some time ago I had the same problem. In that case it was solved by updating the components of the "PDF xChange Viewer".

Here is the real problem. It will be fixed in the next build.
1. Temporary workaround, please display bookmarks pane before bookmarks enumeration.
2. Small fix for your code:
replace:

Code: Select all

bkm.execute(this.gotoNamedDest(bkm.name));

to:

Code: Select all

bkm.execute();

Hello,

I downloaded the mostrecent update of the pdf-component. However, the problem stillconsists.

At first, I displayed the navigation and then Iread-out the pages.

I adapted the code according to yourexplanation. However, there remain some problems to be solved.

1. Has the pdf-component to be in the visible area in order toread-out the page numbers?
2. The read-out page numbers of the bookmarks sometimes do not coincidewith the real page numbers.

Will this problem be solved in the next update? If so, when will thatcome out?


Best regards

Hi Heiko,
In the new build there is no need to display the bookmarks pane for reading bookmarks, and viewer component does not need to be in the visible area. Also please note that page numbers are displayed by JS which is zero based, so to see the real page number you should add 1.

Code: Select all

s += '=====' + (this.pageNum + 1);

If you have any PDFs in which you cannot get the right bookmark page number please send it to us, so we can investigate the problem here.

HTH.

Hello,

Once page numbers are read in correctly and another time not, even within one document.

Codes are called on as follows:

Code: Select all

Call pdfDateivorschau.OpenDocument("C:\Test.pdf", strPasswort, id, PXCVA_Flags.PXCVA_NoUI)
JavaScript_Code (id)

Sub JavaScript_Code(DokumentenNr)
  
    'Alle Bookmarks werden ausgelesen
    jsCode = "function DumpBookmark(bkm, nLevel)"
    jsCode = jsCode & "{"
    jsCode = jsCode & "var s = '';"
    jsCode = jsCode & "for (var i = 0; i < nLevel; i++) s += ' ';"
    jsCode = jsCode & "s += '+-';"
    jsCode = jsCode & "bkm.execute(this.gotoNamedDest(bkm.name));"
    jsCode = jsCode & "s += bkm.name;"
    jsCode = jsCode & "s += '=====' + (this.pageNum + 1);"
    jsCode = jsCode & "s += '\n';"
    jsCode = jsCode & "if (bkm.children != null)"
    jsCode = jsCode & "{"
    jsCode = jsCode & "for (var i = 0; i < bkm.children.length; i++)"
    jsCode = jsCode & "s += DumpBookmark(bkm.children[i], nLevel + 1);"
    jsCode = jsCode & "}"
    jsCode = jsCode & "return s;"
    jsCode = jsCode & "}"
    jsCode = jsCode & "DumpBookmark(this.bookmarkRoot, 0);"

Call pdfDateivorschau.RunJavaScript(jsCode, jsResult, DokumentenNr)

Further I tried the following:

Code: Select all

Sub JavaScript_Code(DokumentenNr)
    
    'Alle Bookmarks werden ausgelesen
    jsCode = "function DumpBookmark(bkm, nLevel)"
    jsCode = jsCode & "{"
    jsCode = jsCode & "var s = '';"
    jsCode = jsCode & "for (var i = 0; i < nLevel; i++) s += ' ';"
    jsCode = jsCode & "s += '+-';"
    jsCode = jsCode & "bkm.execute();"
    jsCode = jsCode & "s += bkm.name;"
    jsCode = jsCode & "s += '=====' + (this.pageNum + 1);"
    jsCode = jsCode & "s += '\n';"
    jsCode = jsCode & "if (bkm.children != null)"
    jsCode = jsCode & "{"
    jsCode = jsCode & "for (var i = 0; i < bkm.children.length; i++)"
    jsCode = jsCode & "s += DumpBookmark(bkm.children[i], nLevel + 1);"
    jsCode = jsCode & "}"
    jsCode = jsCode & "return s;"
    jsCode = jsCode & "}"
    jsCode = jsCode & "DumpBookmark(this.bookmarkRoot, 0);"

Call pdfDateivorschau.RunJavaScript(jsCode, jsResult, DokumentenNr)
