Lightweight event delegation
Install
npm install delegate-it
Setup
const delegate = require('delegate-it');
import delegate from 'delegate-it';
Usage
Add event delegation
With the default base (document
)
delegate('.btn', 'click', event => { console.log(event.delegateTarget); });
With an element as base
delegate(document.body, '.btn', 'click', event => { console.log(event.delegateTarget); });
With a selector (of existing elements) as base
delegate('.container', '.btn', 'click', event => { console.log(event.delegateTarget); });
With an array/array-like of elements as base
delegate(document.querySelectorAll('.container'), '.btn', 'click', event => { console.log(event.delegateTarget); });
Remove event delegation
With a single base element (default or specified)
const delegation = delegate(document.body, '.btn', 'click', event => { console.log(event.delegateTarget); }); 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.
const delegations = delegate('.container', '.btn', 'click', event => { console.log(event.delegateTarget); }); delegations.forEach(function (delegation) { delegation.destroy(); });
