As you delve deeper into web development, knowing how to manipulate HTML attributes dynamically using JavaScript opens up a world of possibilities. Whether you’re adding new attributes, removing existing ones, or updating their values, understanding attribute manipulation is key to creating interactive and responsive web pages.

Let’s explore these concepts with simple and up-to-date code examples.

Adding Attributes

Adding attributes to HTML elements dynamically is straightforward with the setAttribute() method. You can target elements by ID, class, or tag name and add the desired attribute along with its value.

const element = document.getElementById('myElement');
element.setAttribute('data-custom', 'value');

Removing Attributes

Removing attributes from HTML elements is just as easy. You can use the removeAttribute() method to remove a specific attribute from an element.

const element = document.getElementById('myElement');
element.removeAttribute('data-custom');
