API

event(el, str, callback, capture)

Add an event listener.

var bind = require('event');

bind(document.body, 'click', function(ev, target) {
  //do something
});

The second argument of the callback is the element (cross browser target) that trigerred the event.

Delegate events.

bind(document.body, 'click button.clickable', function() {
  //do something only when buttons with the 
  //class clickable are clicked
});

Filter events.

var input = document.querySelector('input');

bind(input, 'keypress > 13', function() {
  //do something only on enter
});

Returns an array (topic, callback, capture) in case you want to remove the listener.

.off(el, topic, callback, capture)

Remove an event listener.

bind.off(document.body,'click', fn);
