append method
The Element.append() method
inserts a set of Node objects or string objects after
the last child of the Element. String objects
are inserted as equivalent Text nodes.
Differences from Node.appendChild:
Element.append()allows you to also append string objects, whereasNode.appendChild()only acceptsNodeobjects.Element.append()has no return value, whereasNode.appendChild()returns the appendedNodeobject.Element.append()can append several nodes and strings, whereasNode.appendChild()can only append one node.
Implementation
external void append(JSAny nodes);
