Filling form, radio options with same name

[rienheuver]

I'm trying to fill out a form from a third-party and they screwed up their form pretty big. When I get the radio group and log the opttons like this:
console.log(form.getRadioGroup('Client 10').getOptions());
I get the following output:
[ 'Keuze', 'Keuze' ]
I.e. they are exactly the same. When I then do
form.getRadioGroup('Client 10').select('Keuze');
It will always select the second option of the radio group. Obviously this form is pretty bad, but it would help a lot if I could select an option based on the index in the options instead of the string.

Did you find a work around for this? im having the same issue.

[rienheuver]

No, I haven't found a method yet. Currently my project is still in proof-of-concept phase, but this will get annoying eventually.

Ok Thanks!

This can be done if you use the lower level PDFAcroRadioButton API. See also PDFRadioGroup.

I would like to provide better support for this though. I've added it to the roadmap for tracking: #998.

Unfortunately, I don't have time to create a proper PR at this point, so I'm adding this as a comment to this thread for now.

PDFRadioGroup can be modified with the following method:

selectByIndex(index: number) {
  assertIs(index, 'index', ['number']);

  this.markAsDirty();

  const onValues = this.acroField.getOnValues();

  if (onValues[index]) {
    this.acroField.setValue(onValues[index]);
  }
}

I also have a simple solution that does not require changes to the library, the value can be selected as follows:

const pdfDoc = await PDFDocument.load(...);
const form = pdfDoc.getForm();
const field = form.getRadioGroup(fieldName);
const onValues = field.acroField.getOnValues();

if (onValues[index]) {
  field.acroField.setValue(onValues[index]);
}

This solution worked for me @rienheuver @mtzmlz
