Class Text

An element representing a rich text region. All text in a Document is contained within Text elements. A Text element can be contained within an Equation, EquationFunction, ListItem, or Paragraph, but cannot itself contain any other element. For more information on document structure, see the guide to extending Google Docs.

// Gets the body contents of the active tab.
var body = DocumentApp.getActiveDocument().getActiveTab().asDocumentTab().getBody();

// Use editAsText to obtain a single text element containing
// all the characters in the tab.
var text = body.editAsText();

// Insert text at the beginning of the tab.
text.insertText(0, 'Inserted text.\n');

// Insert text at the end of the tab.
text.appendText('\nAppended text.');

// Make the first half of the tab blue.
text.setForegroundColor(0, text.getText().length / 2, '#00FFFF');

The provided regular expression pattern is independently matched against each text block contained in the current element.
