Detailed documentation

`addBookmark(position)`

Adds a Bookmark at the given Position.

// Gets the tab body and adds a paragraph.
const paragraph = documentTab.getBody().appendParagraph('My new paragraph.');

// Creates a position at the first character of the paragraph text.
const position = documentTab.newPosition(paragraph.getChild(0), 0);

// Adds a bookmark at the first character of the paragraph text.
const bookmark = documentTab.addBookmark(position);

// Logs the bookmark ID to the console.
console.log(bookmark.getId());

`addNamedRange(name, range)`

Adds a NamedRange, which is a Range that has a name and ID to use for later retrieval. Names aren't necessarily unique, even across tabs; several different ranges in the same document can share the same name, much like a class in HTML. By contrast, IDs are unique within the document, like an ID in HTML. After you add a NamedRange you can't modify it, you can only remove it.

Any script that accesses the tab can access a NamedRange. To avoid unintended conflicts between scripts, consider prefixing range names with a unique string.

// Creates a named range that includes every table in a tab by its ID.
// TODO(developer): Replace the IDs with your own.
var documentTab = DocumentApp.openById(DOCUMENT_ID).getTab(TAB_ID).asDocumentTab();
var rangeBuilder = documentTab.newRange();
var tables = documentTab.getBody().getTables();
for (var i = 0; i < tables.length; i++) {
  rangeBuilder.addElement(tables[i]);
}
documentTab.addNamedRange('Tab t.0 tables', rangeBuilder.build());

Parameters

Name	Type	Description
`name`	`String`	The name for the range, which doesn't need to be unique; range names must be between 1-256 characters.
`range`	`Range`	The range of elements to associate with the name; the range can be a search result or manually constructed with `newRange()`.

Return

NamedRange — The NamedRange.

`getBody()`

Retrieves the tab's Body.

Tabs may contain different types of sections (for example, HeaderSection, FooterSection). The active section for a tab is the Body.

Element methods in DocumentTab delegate to the Body.

// Opens the Docs file and retrieves the tab by its IDs. If you created your script from within
// a Google Docs file, you can use DocumentApp.getActiveDocument().getActiveTab() instead.
// TODO(developer): Replace the IDs with your own.
const documentTab = DocumentApp.openById(DOCUMENT_ID).getTab(TAB_ID).asDocumentTab();

// Gets the tab body.
const body = documentTab.getBody();

// Gets the body text and logs it to the console.
console.log(body.getText());

Return

Body — The tab's body section.

`getBookmark(id)`

Gets the Bookmark with the given ID. This method returns null if no such Bookmark exists within this tab.

// Opens the Docs file and retrieves the tab by its IDs. If you created your script from within
// a Google Docs file, you can use DocumentApp.getActiveDocument().getActiveTab() instead.
// TODO(developer): Replace the IDs with your own.
const documentTab = DocumentApp.openById(DOCUMENT_ID).getTab(TAB_ID).asDocumentTab();

// Gets the bookmark by its ID.
const bookmark = documentTab.getBookmark('id.xyz654321');

// If the bookmark exists within the tab, logs the character offset of its position to the
// console. Otherwise, logs 'No bookmark exists with the given ID.' to the console.
if (bookmark) {
  console.log(bookmark.getPosition().getOffset());
} else {
  console.log('No bookmark exists with the given ID.');
}

Parameters

Name	Type	Description
`id`	`String`	The ID for the `Bookmark`.

Retrieves all the Footnote elements in the tab's body.

Calls to getFootnotes cause an iteration over the tab's elements. For large tabs, avoid unnecessary calls to this method.

// Opens the Docs file and retrieves the tab by its IDs. If you created your script from within
// a Google Docs file, you can use DocumentApp.getActiveDocument().getActiveTab() instead.
// TODO(developer): Replace the IDs with your own.
const documentTab = DocumentApp.openById(DOCUMENT_ID).getTab(TAB_ID).asDocumentTab();

// Gets the first footnote.
const footnote = documentTab.getFootnotes()[0];
