W3C Core Reference. Part of the Node Interface.
Appends something (an element/node/object) created by a createElement or createTextNode method as the last child of an existing node, that is is becomes the lastChild attribute of the object/node to which is was appended.
// get a reference to an existing object obj = document.getElementById("one"); // create a paragraph element newobj = document.createElement("p"); // create some visible text textnode = document.createTextNode("Some text"); newobj.appendChild(textnode); // append it and make visible in document obj.appendChild(newobj); }
Appends (adds to the end) of the existing obj the newly created newobj.
The newly created element (newobj) has a single instance and cannot be added to two (or more) nodes. Assuming you want to add the same element to two existing nodes, then if two appendChild methods are issued newobj would be added to the last Node.
