What throws DOMErrors

Question

Introduction

DOMError is an interface defined by the DOM.

I would like to check if the browser supports it. Naive check

window.DOMError !== undefined

A better check would be to use an action that throws a DOMError and checks that

err instanceof DOMError === true

Question

What actions throw DOMErrors?

Answer 1

A DOMErroris the condition for an exception-based error. It will never be thrown, except that an object that implements both DOMErrorand DOMExceptioncan be dropped as DOMException.

Answer 3

DOMErrors occur when trying to create an invalid DOM element or pass a nonexistent node as an argument to node manipulation methods. In other words, an exception occurs when the operation cannot be completed.

Example:

document.querySelectorAll("div:foo");

This raises a DOMError when div: foo does not exist.
