Lightweight event delegation.
You can get it on npm.
npm install delegate --save
If you're not into package management, just download a ZIP file.
var delegate = require('delegate');<script src="dist/delegate.js"></script>delegate('.btn', 'click', function(e) {
console.log(e.delegateTarget);
}, false);delegate(document.body, '.btn', 'click', function(e) {
console.log(e.delegateTarget);
}, false);delegate('.container', '.btn', 'click', function(e) {
console.log(e.delegateTarget);
}, false);delegate(document.querySelectorAll('.container'), '.btn', 'click', function(e) {
console.log(e.delegateTarget);
}, false);var delegation = delegate(document.body, '.btn', 'click', function(e) {
console.log(e.delegateTarget);
}, false);
delegation.destroy();Note: selectors are always treated as multiple elements, even if one or none are matched. delegate() will return an array.
var delegations = delegate('.container', '.btn', 'click', function(e) {
console.log(e.delegateTarget);
}, false);
delegations.forEach(function (delegation) {
delegation.destroy();
