Error TS2339: The 'style' property is not found in the 'Element' type

Check out this code snippet:

ngOnInit() {
const navSlide = () => {
  const burger = document.querySelector('.burger');
  const nav = document.querySelector('.nav-links');
  const navLinks = document.querySelectorAll('.nav-links li');
  burger.addEventListener('click', () => {
    nav.classList.toggle('nav-active');
  });
  navLinks.forEach((link, index) => {
  link.style.animation = `navLinkFade 0.5s ease forwards ${index / 7 + 0.3}s`;
   });
};
navSlide();

}

The error message I'm encountering is:

Property 'style' does not exist on type 'Element'.ts(2339)

Any suggestions on how to resolve this issue?

Answer №1

querySelectorAll retrieves a collection of NodeList that are known to contain Elements, not necessarily HTMLElements. In this scenario, you are aware that these elements are indeed HTMLElements (specifically HTMLLIElements), so you can implement a type assertion as follows:

navLinks.forEach((link, index) => {
    (link as HTMLElement).style.animation = `navLinkFade 0.5s ease forwards ${index / 7 + 0.3}s`;
});

Refer to Mike S.'s comment for further insights - while I am not well-versed in Angular, there may be a more tailored Angular-specific solution available.

Answer №2

One alternative to using the NodeList returned by T.J.'s suggestion is to manually type out the QuerySelectorAll function.

const links = document.querySelectorAll<HTMLElement>('.links li');
