[Proto-Scripty] Re: attach one observer for many events to an element

[T.J. Crowder]

Hi,

Just reuse the same handler for multiple events:

    function handler(event) { /* ... */ }

    element
        .observe('change', handler)
        .observe('paste', handler);

If you need to bind, do that first so you're not creating unnecessary
extra functions:

    var Thingy = Class.create((function() {

        function handler(event) { /* ... */ }

        function hookUsUp(element) {
            var boundHandler = handler.bind(this);
            element
                .observe('change', boundHandler)
                .observe('paste', boundHandler);
        }

        return {hookUsUp: hookUsUp};
    })());

HTH,
