El método insertAdjacentElement() inserta un elemento nodo dado en una posición dada con respecto al elemento sobre el que se invoca.

Syntax

targetElement.insertAdjacentElement(position, element);

Parameters

position
A DOMString representing the position relative to the targetElement; must be one of the following strings:
  • 'beforebegin': Before the element itself.
  • 'afterbegin': Just inside the element, before its first child.
  • 'beforeend': Just inside the element, after its last child.
  • 'afterend': After the element 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();
  activeElem.insertAdjacentElement('beforebegin',tempDiv);
  setListener(tempDiv);
});

afterBtn.addEventListener('click', function() {
  var tempDiv = document.createElement('div');
  tempDiv.style.backgroundColor = randomColor();
  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().
