Iterating over all fields in a PDF form with JavaScript

Question

I would like to modify some properties for all fields in a PDF form in response to the user clicking a button.

Which property or method will return me the collection of fields so that I can iterate over them?

Answer 1

If there is a collection of fields I still haven't found it. There is a way to iterate over all the fields though.

The numFields property of the doc object gives the number of fields, getNthFieldName(index) returns the name of the field with that index and getField(fieldName) returns the field of that name.

for (var fieldNumber = 0; fieldNumber < numFields; fieldNumber ++)
{
  getField(getNthFieldName(fieldNumber)).value = 'Scripty Was Here';
}
