Change the class of <body> when the button is clicked

One of my tasks involves adding a button that, when clicked, should give the body the class "open-menu". Implementing this using jQuery was quite straightforward - I just needed to add the following line of code:

$('.burger').click(function() { $('body').toggleClass('menu-open'); }); };

However, I am facing difficulties in achieving the same functionality in Angular with TypeScript! Most of the resources I found online only cover toggling classes on the same element!

Answer №1

To implement a toggle function in your Component Class, you can simply add a boolean property like so:

menuOpened: boolean = false;

Next, when the button is clicked, you should do two things:

  1. Toggle the value of menuOpened:

    <button (click)="menuOpened = !menuOpened">Click to Toggle Menu</button>
    
  2. Add the CSS class conditionally based on the value:

    <div [class.menu-open]="menuOpened"></div>

Answer №2

Can be done in a straightforward manner without using AngularJS:

document.body.classList.add('menu-open');
To reverse this action:
document.body.classList.remove('menu-open')
