querySelector

Why wouldn't the querySelector method work? For instance, instead of document.getElementByID('headline'), use document.querySelector('headline') ?

1 Answer

document.getElementById('headline') is equivalent to document.querySelector('#headline'). The # specifies that 'headline' is an id. document.querySelector('headline') selects the first element with a <headline> tag, which is not a standard html tag. If the element with the id 'headline' has an <h1> tag and is the first h1 element on the page, you could select it using document.querySelector('h1').
