object.className or object.getAttribute(“className/class”)?

Question

Between both those :

Javascript

function setCss(object, css) {
    return (object.className = css);
}
function getCss(object, css) {
    return ob         


        

Answer 1

getAttribute("class") is more universal, because it can be used in different types of documents. In XML documents, most importantly. Including SVG.

element.className works only in HTML. It is described in the DOM level 2 HTML specs.
