Package Exports

enot

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 (enot) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Enot

Enot is an event notation system. Rules are similar to CSS, but for events.

Inspired by xtags events, backbone events and component/events notations.

Examples

click - call on click

click:after(100) - call 100ms after click happens

click:throttle(200) - fire not more often than 200ms

click:one - fire once

keypress:pass(ctrl + alt + del) - catch windows task manager call

keypress:pass(/y/i) + keypress:pass(/e/i) + keypress:pass(/s/i) - catch user’s consent.

touch - normalized crossbrowser gesture

window message - call on window gets message

document unload - call on user is going to leave

.bad-link click - elements matching selector click

document click:delegate(.bad-link) - the same as above but in a better way

this.parentNode click:delegate(this.childNodes) - hang click on parent, delegate to children

this.childNodes click - catch click on every children

.element click, document keypress:pass(enter) - bind two callbacks

all - call on any event

Usage

1. Install

npm install enot

2. Use

var evtObj = enot.parse(target, 'document click:pass(right_mouse_button)', callback);

/*
evtObj === [{
    target: document,
    handler: fn,
    event: 'click'
}]
*/

evtObj.target.addEventListener( evtObj.event, evtObj.handler[0] );

Targets

.some-valid-selector > .inner-element
parent
document
window
body
this.property — reference to target properties

- SHIFT: 16
- SPACE: 32

- RIGHT_MOUSE: 3
- MIDDLE_MOUSE:
:defer(100) — invoke callback 100 ms after

Modifiers can be combined, e.g. click:delegate(.inner-tag):pass(right_mouse)
