FAQ

1. Q: How can I retrieve the field code of a field in Aspose.Words for Node.js?
   A: Use the field.getFieldCode() method on the Field object. The returned string contains the complete field code, including the field type and any switches.

2. Q: How do I obtain the displayed result (field result) of a field?
   A: Read the field.result property. This returns the text that Word shows after the field is evaluated, such as the merged value of a MERGEFIELD.

3. Q: Can I differentiate between the field code and the field result while iterating through all fields in a document?
   A: Yes. When looping through document.range.fields, call field.getFieldCode() for the definition and read field.result for the current output. This lets you process each part separately.

4. Q: Is it possible to get the type of a field (e.g., MERGEFIELD, PAGE) programmatically?
   A: Yes. Read the field.type property: it returns a FieldType value, such as FieldType.FieldMergeField or FieldType.FieldPage.

5. Q: Are there other useful properties of a Field object I can access?
   A: Besides getFieldCode() and result, you can use the field.isLocked property to check if the field is locked, field.update() to force an update, and field.remove() to delete the field from the document.
