get all elements with onclick in them?

Question

I am looking for a way to list all elements that have onclick event on a page.

Answer 1

Answer from @Josh the Goods didn't work for me, I had to slightly modify it.

var allElements = document.getElementsByTagName('*');
for (var i = 0; i < allElements.length; i++) {
    if ($._data(allElements[i])['events'] != undefined 
        && $._data(allElements[i])['events']['click'] != undefined) {
        console.log(allElements[i]);
        for (var ii = 0; ii < $._data(allElements[i])['events']['click'].length; ii++) {
            console.log($._data(allElements[i])['events']['click'][ii].handler);
        }
    }
}
