A generic EventTarget
Proxy wrapper to chain and/or group common operations, used to showcase this blog post code.
This module is 450 bytes once minified (plus brotli).
Single
$('css'[, parent])
to query the document and handle a single reference$(target)
to wrap directly an EventTarget implemented interface$(t).on(type, ...rest)
to add a listener and chain the proxy$(t).emit(type, ...rest)
to dispatch an event and chain the proxy$(t).field
to get the field value$(t).field = value
to set a field value$(t).method(...args)
to invoke a (bound) method and chain the proxy$(t).valueOf()
to retrieve the wrapped reference
List
$$('css'[, parent])
to query the document and handle a list of references$$([target1, target2, ...targetN])
to wrap directly more EventTarget implemented interfaces$$([...t]).on(type, ...rest)
to add a listener to all targets and chain the proxy$$([...t]).emit(type, ...rest)
to dispatch many events and chain the proxy$$([...t]).field
to get all fields values as array$$([...t]).field = value
to set all fields values$$([...t]).method(...args)
to invoke all (bound) methods and chain the proxy$$([...t]).valueOf()
to retrieve the list of references$$([...t]).length
to retrieve thelength
of the list
Plugins
This module exports a plugins
Map to enhance the utilities as needed.
// import {$, $$, plugins} from 'https://unpkg.com/handy-wrap';
import {$, $$, plugins} from 'handy-wrap';
const html = Symbol('html');
plugins.set(html, (value, name, proxy) => {
const output = [];
for (const node of (value instanceof NodeList ? value : [value]))
output.push(node.outerHTML);
return output.join('');
});
// returns the document.body HTML
$('body')[html];
// returns all <LI> as HTML
$$('li')[html];
