event-map

A module to ease the addition and removal of a mapping of delegated listeners to a view. Inspired by Backbone.View's delegateEvents. A mapping consists of an object where the key is an event and optionally a selector as well and the value is a listener function.

Install

npm install event-map --save

Usage

eventMap([domElement,] map [, useCapture])

On a domElement, append these listeners delegated to the provided selectors:

var removeListeners = eventMap(domElement, {
    'click .btn': function(event){ console.log(event.target + 'clicked'); },
    'mouseover h1, h2, a': onRollover,
    'touchstart': onTouchStart
});


//at a later timer, clean up:
removeListeners();

If no domElement is provided, all events are placed on document:

var removeListeners = eventMap({
    'touchstart': onTouchStart,
    'touchmove': onTouchMove,
    'touchend': onTouchEnd
}, true);
