wiretap.js

Put a wiretap on javascript element events

Use before adding events using jQuery or pure javascript.

Usage:

new Wiretap({
    add: function() {
        //fire when an event is bound to element
    },
    before: function() {
        //fire just before an event executes, arguments are automatic
    },
    after: function() {
        //fire just after an event executes, arguments are automatic
    }
});
