This module is a set of additional events and properties to handle user interaction. Use this module in your components to work with UI events universally.

Installation

Usage

var touch = require('touch');

API

1. events (object) - is an object containing a set of read-only keys. The values of these properties are the names of user events depending on the device the script is running on.

   Properties:

   * `start` - mousedown | touchstart
   * `move` - mousemove | touchmove
   * `end` - mouseup | touchend

2. isTouch (boolean) - true if the script is running on mobile device, otherwise - false.

3. getOriginalEvent(event) - returns event object bound to a specific finger (event.changedTouches[0]), in case the script is running on mobile device or event object itself.

   Example:

   document.addEventListener(touch.events.start, function(event){
       event = touch.getOriginalEvent(event);
       console.log(event.pageX);
   });

   events.start property is used in this example to handle mousedown and touchstart events simultaneously, depending on the platform. getOriginalEvent function is called in the event handler to work with the actual event object.

4. init(root) - emulates events dispatching for root elements and all of it's children. root - root element for events dispatching.
