Can you tell me the equivalent in Angular of the hasClass method?

Looking to target elements with a designated class and dynamically update their contents

Answer №1

To access the element reference, utilize ViewChild and then proceed to incorporate ngDoCheck() for checking if the specified class has been added during change detection:

export class NewClassName implements DoCheck {
      @ViewChild('specificElement') specificElement:ElementRef;

      ngDoCheck() {
         if(specificElement.nativeElement.classList.contains('custom-class')) {
            //Perform necessary action
         }
      } 
}

Answer №2

Here is a useful tip for checking if an element has a specific class in JavaScript:

if (element.classList.contains('your-class-name')) {
    // Do something here
}

This method allows you to use plain JavaScript without any external libraries.

Additionally, if you need to remove a class from an element, simply use the following code:

element.classList.remove('your-class-name')
