The $$ returns an Array.

I you only want the first <h2>, then access it at index 0.

alert($$('h2')[0].innerHTML);

Or you can iterate over the Array using prototypejs' .each() method.

$$('h2').each(function(el,i) {
    alert(el.innerHTML);
});

$$(el) creates an array. You need to iterate over each value, or if you just want the first h2, then use .first()

alert($$('h2').first().value());

Check out the API http://globalmoxie./bm~doc/prototype-160-api.pdf

Shouldnt you use .html(). jQuery is using this, i think prototype would use something similar.

Try this: alert($('h2').innerHTML);
