A simple implementation of custom event

In the other words, it could be a demo ofcomponents communication.

Start

Get an instance of EasyEvent.

    var emitter = new EasyEvent();

Then bind your event.

    function callback(data){
        console.log('the data is', data);
    }
    emitter.on('your-event', callback);

    function callback(data){
        console.log('the data is', data);
    }
    // bind with once
    emitter.once('your-event', callback);

Finally, trigger your event.

    emitter.emit('your-event', {data : 'test'});

Remove event.

    emitter.off('your-event');
