A <100 SLOC mangling of a JavaScript eventing system.
- Delegate to it from your own constructed objects!
pwn your objects using obj.prototype = Object.create(pwn);
That's right - don't even worry about your constructor - that's
some pseudo-classical garbage. You pwned it.
- Register new event listeners
// obj.on(event, callback, context)
obj.on('change', func, this); // register listener with this context
obj.on('change', func); // register listener with obj's context- Unregister old event listeners
// obj.off(event, callback, context)
obj.off('change', func, this); // remove like callbacks with like context
obj.off('change', func); // remove like callbacks with any context
obj.off('change'); // remove all registered listeners to 'change'
obj.off(); // remove all registered listeners to all events- Set properties
// obj.set(property, value)
obj.set('frequency', 440) // returns 440
/**
* Triggers callbacks registered to 'change'
* as callback(obj, {
* p: property,
* w: wornValue, // (oldValue)
* n, value
* })
*/- Get properties
// obj.get(property, value)
obj.get('frequency') // returns 440- Trigger events yourself
//obj.trigger(event, options)
obj.trigger('change', 'p', 'w', 'n', 'e', 'd');
/**
* Triggers callbacks registered to 'change'
* as callback(obj, 'p', 'w', 'n', 'e', 'd');
*/They're even chainable (on, off, and trigger)!
