Element: getAttribute() method

The getAttribute() method of the Element interface returns the value of a specified attribute on the element.

If the given attribute does not exist, the value returned will either be null or "" (the empty string); see Non-existing attributes for details.




  • attributeName is the name of the attribute whose value you want to get.

Return value

A string containing the value of attributeName.


<!-- example div in an HTML DOC -->
<div id="div1">Hi Champ!</div>
// in a console
const div1 = document.getElementById("div1");
//=> <div id="div1">Hi Champ!</div>

const exampleAttr = div1.getAttribute("id");
//=> "div1"

const align = div1.getAttribute("align");
//=> null


Lower casing

When called on an HTML element in a DOM flagged as an HTML document, getAttribute() lower-cases its argument before proceeding.

Non-existing attributes

All modern web browsers return null when the specified attribute does not exist on the specified element.

Retrieving nonce values

For security reasons, CSP nonces from non-script sources, such as CSS selectors, and .getAttribute("nonce") calls are hidden.

let nonce = script.getAttribute("nonce");
// returns empty string

Instead of retrieving the nonce from the content attribute, use the nonce property:

let nonce = script.nonce;
