Hamburger Menu JavaScript

 

 

Introduction to Hamburger Menu JavaScript

Hamburger Menu in JavaScript is defined as a list of links or buttons or content on the navigation bar or Side Bar that can be hidden or shown simultaneously when we click a button like triple equal on the right side of the navigation bar. The hamburger menu is nothing but a navigation bar that is either vertically or horizontally. It is mainly more useful with smaller screen devices because mobile screens cannot have the same space as the PCs. Instead of showing the navigation bar, smaller devices shown with a hamburger menu to access all the features like PCs. Hamburger Menu is an advanced feature of JavaScript with a high animated look and feel.

Real-time Example: If we want to display the main content like Home, Register, Login, Order details, etc. In small-screen devices like mobiles, notepads, etc. Then prefer Hamburger Menu.

Advantage:

  • Best suited for all types of screen sizes.

How does it work in JavaScript?

Hamburger Menu in JavaScript work is based on querySelector(), addEventListener() and toggle() functions.

  • querySelector(): It creates a navigation bar by selecting a div class from HTML code and, also it makes the navigation bar to toggle by selecting one more div class from HTML code.

Example:

<div class="navbar"> //class="navbar" used by querySelector() for creating navigation bar
<div class="navToggle"> //class="navToggle" taken inside the querySelector() as argument for displaying navigation bar toggle
</div>
</div>
  • addEventListener(): It makes the navigation bar show or hidden by taking click.
  • toggle(): It activates the toggle functionality either active or inactive.

Syntax:

let navigataionBar = document.querySelector('navigation class from HTML code');
let navigationToggle = document.querySelector('navigation toggle class from HTML code');
navigationToggle.addEventListener('click', function (event)
{
navigataionBar.classList.toggle('active')
});
