Native API

once()

happen.once(element, options) fires an event once. The element must be a DOM element. options must have a type for event type, then can have options:

Keyboard Events

• keyCode
• charCode
• shiftKey
• metaKey
• ctrlKey
• altKey

Mouse Events

• detail
• screenX
• screenY
• clientX
• clientY
• ctrlKey
• altKey
• shiftKey
• metaKey
• button

Touch Events

• touchstart
• touchmove
• touchend

var element = document.getElementById('map');

// click shortcut
happen.click(element);

// dblclick shortcut
happen.dblclick(element);

// custom options
happen.dblclick(element, { shift: true });

// any other event type under MouseEvents
happen.once(element, {
    type: 'mousewheel',
    detail: -100
});

// The once api takes
happen.once(
    // element
    element, {
        // event type (e.type)
        type: 'mousewheel',
        // any other options
        detail: -100
    });

// touch events
happen.once(element, {
        type : 'touchstart',
        touches : [{
                pageX : 800,
                pageY : 800
            },
            {
                pageX : 400,
                pageY : 400
            }]
    });

jQuery Plugin

// Shortcut - 'click' is shorthand for { type: 'click' }
$('.foo').happen('click');

// Longhand - specify any sort of properties
$('.foo').happen({ type: 'keyup', keyCode: 50 });

// Works on any jQuery selection
$('.foo, .bar').happen('dblclick');

Shortcuts:

• happen.click
• happen.dblclick
• happen.mousedown
• happen.mouseup
• happen.mousemove
• happen.keydown
• happen.keyup
• happen.keypress

Use it with a testing framework, like Jasmine or Mocha.

(IE tests failing due to Chai)
