InsertAdjacentHTML in JavaScript

InsertAdjacentHTML is a method in JavaScript that allows you to insert HTML content at a specified position relative to an element. It is a powerful tool that can help you dynamically change the structure of your web page without reloading it.


The syntax for using the InsertAdjacentHTML() method is as follows:

element.insertAdjacentHTML(position, text);


  • position: The position relative to the element where the HTML content will be inserted. It can be one of the following values:
  • 'beforebegin': Inserts the HTML content immediately before the element.
  • 'afterbegin': Inserts the HTML content inside the element, before its first child.
  • 'beforeend': Inserts the HTML content inside the element, after its last child.
  • 'afterend': Inserts the HTML content immediately after the element.
  • text: The HTML content that will be inserted.


Let's say we have an HTML div with an id of "myDiv". We can use the InsertAdjacentHTML method to add some content to it dynamically:

// Get the div element
var div = document.getElementById("myDiv");

// Insert HTML content before the div
div.insertAdjacentHTML("beforebegin", "This is some text before the div!");

// Insert HTML content inside the div
div.insertAdjacentHTML("afterbegin", "InsertAdjacentHTML ExampleThis is some text inside the div!");

// Insert HTML content after the div
div.insertAdjacentHTML("afterend", "This is some text after the div!");

This will add a paragraph of text before the div, an h3 heading and another paragraph of text inside the div, and a final paragraph of text after the div.

It's important to note that while InsertAdjacentHTML is a powerful method, it can also be a security risk if not used properly. Always validate any user input before inserting it into your web page to prevent XSS attacks.
