My project is built on angular 4, and I am looking to change the background color of the <body> tag using the component's .ts file when a specific element is clicked.
The issue I'm facing is that once the color is changed to blue, it persists even when clicking on other components. I want the blue color to be removed whenever any other component is clicked, so that only the selected elements trigger the change in background color.
If you're looking to enhance your component, one option is to incorporate a directive and assign it to the wrapper div of the component. By adding a specific class to the body while the directive is active, and then removing it upon destruction of the directive:
Directive:
import { Directive, AfterViewInit, OnDestroy } from '@angular/core';
@Directive({ selector: '[myDirective]' })
export class ChangeColorDirective implements OnDestroy, AfterViewInit {
ngAfterViewInit() {
document.querySelector('body').classList.add('blue');
}
ngOnDestroy(): void {
document.querySelector('body').classList.remove('blue');
}
}
styles.css
.blue {
background-color: blue
}
