Prototype equivalent for jQuery live function

Question

I need to bind event listener to all dynamicaly created elements by given css selector.

In jQuery, that would be

$(\".foo\").live(\"click\", function         


        

Answer 1

This is usually done with Event#findElement:

document.observe('click', function(e, el) {
  if (el = e.findElement('.foo')) {
    // there's your `el`
    // might want to stop event at this point - e.stop()
  }
});
