Question

Is there a better/faster way to find all elements with a class name in browsers that don’t support document.getElementsByClassName?

var elements = document.getElementsByTagName('*'),
    results = [];

for (var i=0; i < elements.length; i++) {
  (elements[i].className === selector) ? results.push(elements[i]) : null;
}
return results;

And no I don’t want to use jQuery 🙂

I would check out John Resig’s comparison on methods for simulating document.getElementsByClassName.
