I am eager to perform DOM manipulation similar to jQuery but within the context of Angular 6

Is there a way to modify the background color of the main div when a button is clicked?

<div>
    <p>I'd like to be able to change the background color of the parent div by clicking a certain button.
    </p>
   <button (click)="changeColour()" id="buy-now">BUY NOW</button>
<div>

Answer №1

One way to dynamically add a class to the parent div is by using conditional statements such as [class.red]="isRed". You can then alter this condition by invoking the changeColor() function and setting isRed = true.

Answer №2

Forget about JQuery for a moment!

For a more elaborate explanation:

In your HTML code, you would utilize an expression to define the class

<div [ngClass]="{'blue' : isBlue }"> 
    <p>I aim to modify the background-color of the parent div with the click of a button.
    </p>
   <button (click)="changeColour()" id="buy-now">BUY NOW</button>
<div>

Subsequently, your TypeScript script would manage the toggling of the value. You can incorporate expressions/class names as necessary:

export class AppComponent  {
isBlue = false;
  changeColour() {
    this.isBlue = !this.isBlue;
    console.log(this.isBlue);
  }
  name = 'Angular';
}

Take a look at the operational example here:
