Return

TableOfContents — The new copy.

Scripts that use this method require authorization with one or more of the following scopes:

editAsText()

Obtains a Text version of the current element, for editing.

Use editAsText for manipulating the elements contents as rich text. The editAsText mode ignores non-text elements (such as InlineImage and HorizontalRule).

Child elements fully contained within a deleted text range are removed from the element.

const body =
    DocumentApp.getActiveDocument().getActiveTab().asDocumentTab().getBody();

// Insert two paragraphs separated by a paragraph containing an
// horizontal rule.
body.insertParagraph(0, 'An editAsText sample.');
body.insertHorizontalRule(0);
body.insertParagraph(0, 'An example.');

// Delete " sample.\n\n An" removing the horizontal rule in the process.
body.editAsText().deleteText(14, 25);
Return

Text — a text version of the current element
