How to check header (h1, h2, h3) property of a DOM element?

Question

If I have a reference to a link in Javascript / jQuery, how can I check if it is an <h1>, <h2>, etc.?

Answer 1

I assume you mean inside a heading. You can use :header for that, example:

<h1><a href="#" id="link">link</a></h1>

var isHeading = !!$('#link').closest(':header').length;
