evtify

Eventify any object, Node and browsers.

npm install evtify

Setup:

var obj = {}, anotherObj = {};
evtify(obj, anotherObj, ...);
...

Or:

function Person() {};
Person.prototype = new evtify();
var obj = new Person();
...

Register handler for one or more events with optional context:

obj.on('evt1 evt2', function(eventName, params...) {
		// 'this' will be 'window'
	})
   	.on('evt3', function(eventName, params...) { 
   		// 'this' will be 'context'
   	}, context);

Trigger one or more events:

obj.trigger('evt1 evt2 evt3', args...);

Remove all handlers:

obj.off(); 

Remove handlers of specific events:

obj.off('evt1 evt2'); 

Remove a specific handler of specific events:

obj.off('evt1 evt2', handler); 

Aliases:

• on: addEventListener
• off: removeEventListener
• trigger: fire
