prepend method

The prepend method allows you to insert another element at the beginning of an element. The method takes an element as a parameter, usually created with createElement, or a string. You can add several elements or strings at once by listing them separated by commas.

Syntax

javascriptparent.prepend(element or string);

Example

Let's create a paragraph, set its text and place it on a page at the beginning of the #parent block:

html<div id="parent">
  <p>1</p>
  <p>2</p>
  <p>3</p>
</div>

javascriptlet parent = document.querySelector('#parent');

let p = document.createElement('p');
p.textContent = '!';

parent.prepend(p);

The code execution result:

html<div id="parent">
  <p>!</p>
  <p>1</p>
  <p>2</p>
  <p>3</p>
</div>

Example

Let's put several paragraphs at once at the beginning of the #parent block:

html<div id="parent">
  <p>1</p>
  <p>2</p>
  <p>3</p>
</div>

javascriptlet parent = document.querySelector('#parent');

let p1 = document.createElement('p');
p1.textContent = 'a';

let p2 = document.createElement('p');
p2.textContent = 'b';

parent.prepend(p1, p2);

The code execution result:

html<div id="parent">
  <p>b</p>
  <p>a</p>
  <p>1</p>
  <p>2</p>
  <p>3</p>
</div>

Example

Let's use a string as a method parameter:

html<div id="parent">
  <p>1</p>
  <p>2</p>
  <p>3</p>
</div>

javascriptlet parent = document.querySelector('#parent');
parent.prepend('!');

The code execution result:

html<div id="parent">
  !
  <p>1</p>
  <p>2</p>
  <p>3</p>
</div>
