  • ¶

    Given an element, an object of events, a pool of selectors, and a scope, this function binds those events within the provided scope.

    For example:

    mapEvents(window, { resize: method }, {}, obj)
mapEvents(document.boyd, { 'click {items}': method }, { items: '.class' }, obj);

    var delegate   = require('./delegate');
var tokenize   = require('./tokenize');
var template   = require('./template');
var isFunction = require('./isFunction');

function bindEvent (el, name, method, selectors, scope) {
  var items  = name.split(',');
  var toCall = (isFunction(method) ? method : scope[method]).bind(scope);

  while (items.length) {
    var tokens = tokenize(template(items.pop(), selectors));

    delegate(el, tokens[0], tokens[1], toCall);
  }
}

module.exports = function(el, events, selectors, scope) {
  for (var name in events) {
    bindEvent(el, name, events[name], selectors, scope);
  }
};
