MaterialTextfield type in Typescript

As I embark on my first React TypeScript project, I came across a sample written in pure JavaScript and now I want to rewrite it using TypeScript.

In the Firebase JavaScript sample, we can see:

addCommentForm.onsubmit = function(e) {
  e.preventDefault();
  createNewComment(postId, firebase.auth().currentUser.displayName, uid, commentInput.value);
  commentInput.value = '';
  commentInput.parentElement.MaterialTextfield.boundUpdateClassesHandler();
};

For my TypeScript version, I aim to create a function similar to this:

function resetMaterialTextfield(element: HTMLInputElement) {
  element.value = '';
  element.parentNode.MaterialTextfield.boundUpdateClassesHandler();
}

The burning question on my mind:

  • How should I define 'element' with the appropriate type that has attributes like parentNode, parentElement, and contains MaterialTextfield for calling boundUpdateClassesHandler()?

  • Where does the MaterialTextfield originate from? What is its type and where can I access documentation or tutorials related to this class and library?

Answer №1

Implement type assertion.

(parentElement as DesiredType).updateClasses();
