The ParentNode.append method inserts a set of Node objects or DOMString objects after the last child of the ParentNode. DOMString objects are inserted as equivalent Text nodes.

Differences to Node.appendChild():

  • ParentNode.append() allows you to also append DOMString object, whereas Node.appendChild() only accepts Node objects.
  • ParentNode.append() has no return value, whereas Node.appendChild() returns the appended Node object.
  • ParentNode.append() can append several nodes and strings, whereas Node.appendChild() can only append one node.

Syntax

[Throws, Unscopable] 
void ParentNode.append((Node or DOMString)... nodes);

Parameters

nodes
A set of Node or DOMString objects to insert.

Exceptions

Examples

Appending an element

var parent = document.createElement("div");
var p = document.createElement("p");
parent.append(p);

console.log(parent.childNodes); // NodeList [ <p> ]

Appending text

var parent = document.createElement("div");
parent.append("Some text");

console.log(parent.textContent); // "Some text"

Appending an element and text

var parent = document.createElement("div");
var p = document.createElement("p");
parent.append("Some text", p);

console.log(parent.childNodes); // NodeList [ #text "Some text", <p> ]

ParentNode.append() is unscopable

The append() method is not scoped into the with statement. See Symbol.unscopables for more information.

var parent = document.createElement("div");

with(parent) { 
  append("foo");
}
// ReferenceError: append is not defined 

Polyfill

You can polyfill the append() method in Internet Explorer 9 and higher with the following code:

// Source: https://github.com/jserz/js_piece/blob/master/DOM/ParentNode/append()/append().md
(function (arr) {
  arr.forEach(function (item) {
    if (item.hasOwnProperty('append')) {
      return;
    }
    Object.defineProperty(item, 'append', {
      configurable: true,
      enumerable: true,
      writable: true,
      value: function append() {
        var argArr = Array.prototype.slice.call(arguments),
          docFrag = document.createDocumentFragment();
        
        argArr.forEach(function (argItem) {
          var isNode = argItem instanceof Node;
          docFrag.appendChild(isNode ? argItem : document.createTextNode(String(argItem)));
        });
        
        this.appendChild(docFrag);
      }
    });
  });
})([Element.prototype, Document.prototype, DocumentFragment.prototype]);
