delegate

Lightweight event delegation.

Install

You can get it on npm.

npm install delegate --save

If you're not into package management, just download a ZIP file.

Setup

Node (Browserify)

var delegate = require('delegate');

Browser (Standalone)

<script src="dist/delegate.js"></script>

Usage

Add event delegation

With the default base (`document`)

delegate('.btn', 'click', function(e) {
    console.log(e.delegateTarget);
}, false);

With an element as base

delegate(document.body, '.btn', 'click', function(e) {
    console.log(e.delegateTarget);
}, false);

With a selector (of existing elements) as base

delegate('.container', '.btn', 'click', function(e) {
    console.log(e.delegateTarget);
}, false);

With an array/array-like of elements as base

delegate(document.querySelectorAll('.container'), '.btn', 'click', function(e) {
    console.log(e.delegateTarget);
}, false);

Remove event delegation

With a single base element (default or specified)

var delegation = delegate(document.body, '.btn', 'click', function(e) {
    console.log(e.delegateTarget);
}, false);

delegation.destroy();

With multiple elements (via selector or array)

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();
});
