Bean.js

Bean is a small, fast, cross-platform, framework-agnostic event manager designed for desktop, mobile, and touch-based browsers. In its simplest form – it works like this:

bean.on(element, 'click', function (e) {
console.log('hello');
});

Bean is included in Ender’s starter pack, “The Jeesh”. More details on the Ender interface below.

API

Bean has five main methods, each packing quite a punch.

bean.on()
bean.one()
bean.off()
bean.clone()
bean.fire()

on(element, eventType[, selector], handler[, args ])

bean.on() 

lets you attach event listeners to both elements and objects.

Arguments

element / object (DOM Element or Object) – an HTML DOM element or any JavaScript Object
event type(s) (String) – an event (or multiple events, space separated) to listen to
selector (optional String) – a CSS DOM Element selector string to bind the listener to child elements matching the selector
handler (Function) – the callback function
args (optional) – additional arguments to pas to the callback function when triggered
Optionally, event types and handlers can be passed in an object of the form { ‘eventType’: handler } as the second argument.

Examples

// simple
bean.on(element, 'click', handler);

// optional arguments passed to handler
bean.on(element, 'click', function(e, o1, o2) {
console.log(o1, o2);
}, 'fat', 'ded');

// multiple events
bean.on(element, 'keydown keyup', handler);

// multiple handlers
bean.on(element, {
click: function (e) {},
mouseover: function (e) {},
'focus blur': function (e) {}
});
