Detailed documentation

copy()

Returns a detached, deep copy of the current element.

Any child elements present in the element are also copied. The new element will not have a parent.

Return

EquationSymbol — the new copy

var par = body.appendParagraph('A bold, italicized paragraph.');
par.setBold(true);
par.setItalic(true);

// Retrieve the paragraph's attributes.
var atts = par.getAttributes();

// Log the paragraph attributes.
for (var att in atts) {
  Logger.log(att + ":" + atts[att]);
}

Return

Object — the element's attributes

var body = DocumentApp.getActiveDocument().getBody();

// Obtain the first element in the document body.

var firstChild = body.getChild(0);

// Use getType() to determine the element's type.
if (firstChild.getType() == DocumentApp.ElementType.PARAGRAPH) {
  Logger.log('The first element is a paragraph.');

merge()

Merges the element with the preceding sibling of the same type.

Only elements of the same ElementType may be merged. Any child elements contained in the current element are moved to the preceding sibling element.

The current element is removed from the document.

var body = DocumentApp.getActiveDocument().getBody();

// Append two paragraphs to the document.
var par1 = body.appendParagraph('Paragraph 1.');
var par2 = body.appendParagraph('Paragraph 2.');

// Merge the newly added paragraphs into a single paragraph.
