The insertAdjacentElement() method inserts a given element node at a given position relative to the element it is invoked upon.

Syntax

targetElement.insertAdjacentElement(position, element);

Parameters

position
A DOMString representing the position relative to the targetElement; must match (case-insensitively) one of the following strings:
  • 'beforebegin': Before the targetElement itself.
  • 'afterbegin': Just inside the targetElement, before its first child.
  • 'beforeend': Just inside the targetElement, after its last child.
  • 'afterend': After the targetElement itself.
element
The element to be inserted into the tree.

Return value

The element that was inserted, or null, if the insertion failed.

Exceptions

Exception Explanation
SyntaxError The position specified is not a recognised value.
TypeError The element specified is not a valid element.

Visualization of position names

<!-- beforebegin -->
<p>
<!-- afterbegin -->
foo
<!-- beforeend -->
</p>
<!-- afterend -->
Note: The beforebegin and afterend positions work only if the node is in a tree and has an element parent.

Example

beforeBtn.addEventListener('click', function() {
  var tempDiv = document.createElement('div');
  tempDiv.style.backgroundColor = randomColor();
  if (activeElem) {
    activeElem.insertAdjacentElement('beforebegin',tempDiv);
  }
  setListener(tempDiv);
});

afterBtn.addEventListener('click', function() {
  var tempDiv = document.createElement('div');
  tempDiv.style.backgroundColor = randomColor();
  if (activeElem) {
    activeElem.insertAdjacentElement('afterend',tempDiv);
  }
  setListener(tempDiv);
});

Have a look at our insertAdjacentElement.html demo on Github (see the source code too.) Here we have a sequence of <div> elements inside a container. When one is clicked, it becomes selected and you can then press the Insert before and Insert after buttons to insert new divs before or after the selected element using insertAdjacentElement().
