jQuery var function to pass into a $(query).each() loop. In the stripped instance here, HTML5 data-* tags can control multiple events and types within one each call. "desk" here is a constructor with prototyped functions, but really the typeof test could be replaced with an eval on the value in the data-* attribute.

genericHandler.js

iconFunctions = function() {
    $(this).click(function (e) {
        var f = (e.target.attributes['data-function'] || {}).textContent;
        if (typeof desk[f] === 'function') {
            desk[f](e);
        }
    });
};
