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

object.getAttribute("className"); actually does not work.

The difference is that getAttribute gets the value of a HTML attribute as it is written in the HTML code (with some exceptions).

These values are mostly also the initial values of the properties of the DOM element. But accessing them can yield different values, due to pre-/postprocessing.

For example, if you have an element, el.href gives you the complete (absolute) URL, while el.getAttribute('href') gives you the URL as it was written in the HTML.

Most of the time, you want to access the properties of the DOM element, as these reflect the current state of the element.
