How to capture click event in prototype

Question

I want to prevent default link click behavior. I want that it should not redirect to that link but just show the link in alert box. I have tried this here.

document.on('click', 'a.AjaxLink', function(event, element) {
    alert(element.href);
    return false;
});

Answer 1

this should work

document.on('click', 'a.AjaxLink', function(event, element) {
    event.stop();
    alert(element.href);
});
