Portability of nextElementSibling/nextSibling

Question

I\'m currently writing an accordion and running into the same problem as described in nextSibling difference between IE and FF? - specifically differences between Microsoft\

Answer 1

nextSibling will see HTML code comments, so be sure to keep them out.

Other than that you should be alright since you won't have any text nodes between your tr elements.

The only other issue I could think of would be in Firefox 3 where nextElementSibling hadn't yet been implemented. So if you're supporting that browser, you'll need to manually emulate nextElementSibling. (Pretty sure they had it implemented in FF3.5 though.)

You'll be safer to create a nextElementSibling() function:

tr = tr.nextElementSibling || nextElementSibling(tr);

function nextElementSibling( el ) {
    do { el = el.nextSibling } while ( el && el.nodeType !== 1 );
    return el;
}
