Remove form fields programmatically

Use deleteFormField() with a field reference or ID.

<button id="deleteAllFields">Delete Form Fields</button>
<button id="deleteById">Delete First Field By ID</button>
// Delete all added form fields on button click
document.getElementById('deleteAllFields').addEventListener('click', function () {
  var fields = (pdfviewer.formFieldCollections || []).slice(); // clone to avoid mutation issues
  fields.forEach(function (field) { return pdfviewer.formDesignerModule.deleteFormField(field); });
});

// Delete by ID on button click (example uses the first field's ID)
document.getElementById('deleteById').addEventListener('click', function () {
  if (pdfviewer.formFieldCollections && pdfviewer.formFieldCollections.length > 0) {
    var id = pdfviewer.formFieldCollections[0].id;
    if (id) {
      pdfviewer.formDesignerModule.deleteFormField(id);
    }
  }
});
