Element.getAttributeNames

Element.getAttributeNames returns the attribute names of the element as an Array of strings. If the element has no attributes it returns an empty array.

Using getAttributeNames along with Element.getAttribute, is a memory efficient and performant alternative to accessing Element.attributes.

Syntax

let attributeNames = element.getAttributeNames();

Example

// Iterate over element's attributes
for(let name of element.getAttributeNames())
{
	let value = element.getAttribute(name);
	console.log(name, value);
}
