Utilizing PDF-LIB npm for Managing Numerous Checkboxes in PDF Forms

I am encountering an issue with my PDF form that contains two checkboxes labeled as "Ja" and "Nei". When I attempt to retrieve the names of the checkboxes using const fields = form.getFields(), I only get name===> PDFCheckBox: dodJaNei.

My question is, how can I effectively work with both checkboxes?

const checkBoxxx = form.getCheckBox('dodJaNei')
checkBoxxx.check()

The code snippet provided above successfully checks the first checkbox but not the second one.

Could someone please guide me on how to implement the logic for working with these two checkboxes simultaneously?

Answer №1

Here's a situation I encountered in my code where there were multiple checkboxes for users to select from. Once the user selected their desired checkboxes and submitted the form, the selected checkbox fields were available in the submit function (you can refer to shadcn form checkboxes for more information). I then iterated over them in a loop to get each checkbox and mark them as selected using an array called generalLiabilities.

if (generalLiabilities.length > 0)
    generalLiabilities.forEach((item) => {
      const checkbox = form.getCheckBox(item);
      if (checkbox) {
        checkbox.check();
      }
    });

Please let me know if this solution resolves your issue.
