Package Exports
- delegate-it
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (delegate-it) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
delegate-it 
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();
});
