Universal events binder.

  • Multiple events on(el, 'click touchstart', cb)
  • Event classes on(el, 'click.x', cb), off(el, '.x')
  • Uses native events, if available.
  • Delegate on('.subel', 'click', cb, { target: container })

Usage

npm install emmy

import{on,off,emit}from'emmy'on(el,'evt.foo',e=>{})emit(el,'evt',{x: 1})off(el,'.foo')

API

off = on(target, event, handler, opts?)

Bind event handler to target events.

  • event can be a string or an array, optionally with class suffixes click.tag1.tag2
  • target can be an element, list, or a string to delegate events.
  • opts can provide opts.target for delegate target and listener props.
// draggingon(el,'mousedown touchstart',()=>{// ...init dragon(el,'mousemove.drag touchmove.drag',()=>{// ...handle drag})on(el,'mouseup.drag touchend.drag',()=>{off(el,'.drag')// ...end drag})})// delegateletoff=on('.selector','click',handler,{target: container})// remove listeneroff()

off(target, event?, callback?)

Remove event handler from a target. If callback isn't passed - all registered listeners are removed. If event isn't passed - all registered callbacks for all known events are removed (useful on destroying the target).

// remove handler the standard wayoff(target,'click',handler)// remove handler for all registered eventsoff(target,handler)// remove all events with provided suffix[es]off(target,'.special')

emit(target, event, data?, options?)

Emit an event on a target. event can be a string or an Event instance. If target is an element then data is placed to e.details. options can define triggering params, eg. {bubbles: true}.
