add-view-events

Adds delegated event listeners to an element, optionally binding the callbacks to a context, allows for easy removal of event listeners on cleanup

npm install add-view-events

Usage

var addEvents = require('./add-view-events')

function SomeView() {
  this.el = document.createElement('div')
  this.removeEvents = addEvents(this.el, {
      'click button.some-class': this.shout
  }, this)
}

SomeView.prototype.shout = function() {
  alert(this.msg)
}

SomeView.prototype.remove = function() {
  this.removeEvents()
  this.el.remove()
}

API

addEvents(el, events[, context])

Attach event listeners and returns a cleanup function. el should be an element, events should be an object with 'event elem.selector' keys and function properties.

The context argument is optional and will ensure callbacks are called with their context bound to context
