getPageNthWord returning [object Doc] when used in a text field custom calculation

Report · Dec 11, 2020

Hello

Using Acrobat DC Pro.

When I try to the use the function this.getPageNthWord() or doc.getPageNthWord() and convert it to a string, I get the [object Doc] instead of a word. I can use the function this.getPageNthWord() by intelf on the same document on the console command and it comes up with the first word in the document, but not when I use the function in the custom calculation of a text field.

Bit of context

I have a working custom stamp that brings up an execDialog box for the user to enter stamp data into when the stamp is placed. I would like the stamp dialogbox text fields to be filled in with data from text on the document when the stamp is applied.

Yes, in the context of a dynamic stamp event.source.source returns the document to which the stamp is being applied. And I tried it with event.source.source.pageNum and it worked fine, by the way.

Post your full code, please.

The following code is used in the custom calculation script of the txt1 text field in the InvoiceStamp1 pdf. The lines of problem code are maked with the comment "Problem code". If I ommit the problem code lines the stamp works properly. After reading ls_rbls comment and the reference doc they sent, I think my problem may be that I don't know how to (or if its possible to) use the .getPageNthWord() function inside of a stamp. I did a little bit of testing and I could get the getPageNthWord function to return words from the stamp pdf, but cannot get words from the page of the document the stamp is being applied to. Any insight and help is much appreciated.

// Start code

if (event.source.forReal && (event.source.stampName == "#InvoiceStamp1"))

{

// trims beginning and end of string. Gets rid of leading and trailing; spaces, line feed, caridge returns, horizontal tabs.

function trim (str) {

return str.replace (/(^[\s\n\r\t\x0B]+)|([\s\n\r\t\x0B]+$)/g, '');

This should have worked:

var test1 = this.getPageNthWord(0,0);

What happens if you only enter this code:

var test1 = this.getPageNthWord(0,0);

app.alert(test1.toSource());

I tried adding your code in the stamp code and neither the dialog box nor the alert dialog box show up at all, but the stamp image is still applied to a document page. I tried replacing all of the stamp code to only contain the two lines of code you posted and an alert dialog box appears with

(new String("Vendor"))

which is the first text word that is in the stamp pdf not the first word of the target pdf.

Doing some more reading I found that

this.getPageNthWord(0,0)

can be replaced with

event.source.source.getPageNthWord(0,0)

This seems to get me the first word of the docuemnt being stamped. I don't beleive I understand how this works though since I am trying to now use event.source.source.pageNum function and it does not work.

Report · Dec 14, 2020

Yes, in the context of a dynamic stamp event.source.source returns the document to which the stamp is being applied. And I tried it with event.source.source.pageNum and it worked fine, by the way.

Thank you for your help. You have answered the original posts question so I'll mark you correct! I think I need to do some research and tinkering to see why event.source.source.pageNum does not work but event.source.source.getPageNthWord() does work.

Report · Dec 11, 2020

Since you've mentioned about a bit of context, I think you're not using that function in the correct context.

I am learning JavaScript so bear with me if I say something incorrect, but you can't convert a function to string if the object itself is not defined to begin with.

Running the function by itself in the console is not converting anything to a string, is just reporting back.

So when you say "When I try to the use the function this.getPageNthWord() or doc.getPageNthWord() and convert it to a string" is hard to make sense out of it, unless you mean that you have defined an array for example, or a for loop, with a condition to search for a specific word. And since you've mentioned about using the function by itself, and that it finds the first word in the document, that is not a text string that was taken from a field object for example. The text string that you're referring to is taken from the free text content of your document. That doesn't necessarily mean it was found in an annotation or a comment.

See Example 2, in Page 232 of the Adobe Acrobat SDK JavaScript API JavaScript™ for Acrobat® API Reference "Doc methods"

//Example 2
//Search through the document for the word “Acrobat” and create a link around that word.

for (var p = 0; p < this.numPages; p++)
{
var numWords = this.getPageNumWords(p);
for (var i=0; i<numWords; i++)
{
var ckWord = this.getPageNthWord(p, i, true);
if ( ckWord == "Acrobat")
{
var q = this.getPageNthWordQuads(p, i);
// Convert quads in default user space to rotated
// User space used by Links.
m = (new Matrix2D).fromRotated(this,p);
mInv = m.invert()
r = mInv.transform(q)
r=r.toString()
r = r.split(",");
l = addLink(p, [r[4], r[5], r[2], r[3]]);
l.borderColor = color.red;
l.borderWidth = 1;
l.setAction("this.getURL('http://www.example.com/')");
