Extract Data from PDF Form Fields Using JavaScript
You can extract the values of all the form fields present in a PDF using Instance#getFormFieldValues
. It returns a simple JavaScript object, where the keys refer to the FormField#name
of the form field and the value is either null
, string
, or Array<string>
, depending upon the type of the FormField
:
const formFieldValues = instance.getFormFieldValues(); console.log(formFieldValues); // { textField: 'Text Value', checkBoxField: ['A', 'B'], buttonField: null }
