Evt

Javascript Event delegation. Supposed to be better than Gator, because it has namespaces 😎. Weights about 2.3kb when minified and 930 bytes when gzipped.

Api

// create a new instance
var evt = new Evt('#mydiv');

// Works like a Factory too
var evt2 = Evt('#mydiv');

// Instances are recycled
evt === evt2 // true

// Attach an event
evt.on('click', function (e) {
  // Do stuff
});

// Attach a namespaced event
evt.on('click.open', function (e) {
  e.namespace === 'open' // true
});

// Attach a delegated event
evt.on('click', 'a', function (e) {
  // Do stuff
});

// Chain an event
evt.on('click', 'a', function (e) {
  // Do stuff
}).on('dblclick', function (e) {
  // Do more stuff
});

// Remov all events
evt.off();

// Remove a specific event
evt.off('click');

// Remove all events with a matching namespace
evt.off('.open');

// Remove a specific handler for an event
evt.off('click', func);

// Remove a specific delegated event
evt.off('click', 'a');

// Remove a specific handler for a delegated event
evt.off('click', 'a', func);

Compatibility

Evt should work in recent browsers (IE >= 9). It requires W3C Events (addEventHandler/removeEventHandler), as well as Node.matches
