Erase content in Google Apps Script Document Service

Question

How to flush a document in Google Apps Script Document Service? Do I need to loop through all the kind of elements e.g. paragraph, image, table and remove them as a child? Is there an easier way to delete everything in the body of a document?

Thank you!

Answer 1

According to the Documentation, the Document.setText should be able to clear the document content. I assume the following command should do it.

doc.setText('');

Answer 2

In the current Document of google apps script as doc.setText method is not available this could be achieved by doc.getBody().clear()
