What is the equivalent of jQuery function in Prototypejs?

Question

What is the equivalent of jQuery's

closest() function in prototypeJS?

and html() function in prototypeJS?

Answer 1

I think the .html() function looks like this in prototype

To retrieve the html

$('fruits').innerHTML;
// -> '<ul id="favorite"><li>kiwi</li><li>banana</li><li>apple</li></ul>'

To change the html

$('fruits').update('kiwi, banana and apple');
// -> HTMLElement
