Injecting HTML into Your DOM: A Comprehensive Guide

Appending HTML strings to your DOM is a common task in web development. In this article, we will explore an effective method to achieve this without resorting to the forbidden innerHTML property.

Unleashing the Power of insertAdjacentHTML()

To dynamically add HTML to your document, consider harnessing the insertAdjacentHTML() method. This feature is universally supported by modern browsers and offers a safe and efficient way to manipulate the DOM.

Syntax and Usage

The insertAdjacentHTML() method takes two parameters:

• position: The position where you want to insert the HTML. Valid values include:

  • beforebegin: Before the start of the element
  • afterbegin: Inside the element, before its first child
  • beforeend: Inside the element, after its last child
  • afterend: After the end of the element
• html: The HTML string you want to insert

Practical Example

Imagine you have a

element with an id of test. To append our HTML string to this element, we would use the following code:

let str = '<p>Just some <span>text</span> here</p>';
const div = document.getElementById('test');
div.insertAdjacentHTML('beforeend', str);

This will insert the HTML inside the

element, after its last child.
