JQuery ослабление функций без использования плагина

Я ищу в Интернете список пользовательских функций замедления, которые я могу использовать с jQuery.

Я не заинтересован в использовании плагина для этого, и при этом я не использую jQuery UI.

Я нашел один ниже, который делает хороший маленький отскок, но я ищу несколько других только для того, чтобы у меня были некоторые варианты.

Вместо других функций было бы замечательно краткое объяснение того, как эта функция работает и может быть изменена. Спасибо!

Пример:

$.easing.custom = function (x, t, b, c, d) {
    var s = 1.70158; 
    if ((t/=d/2) < 1) return c/2*(t*t*(((s*=(1.525))+1)*t - s)) + b;
    return c/2*((t-=2)*t*(((s*=(1.525))+1)*t + s) + 2) + b;
}

РЕДАКТИРОВАНИЕ № 1:

Вот онлайн-демонстрация всех функций JQuery UI. Функции источника из пользовательского интерфейса опубликованы ниже в правильном ответе от Джейка.

http://api.jqueryui.com/easings/


Правка № 2:

Оказывается, что приведенная выше примерная функция замедления точно такая же, как и "easeInOutBack" из пользовательского интерфейса jQuery.


Правка № 3:

Вот еще несколько независимых уравнений, которые можно скачать бесплатно ...

При условии, что вы следуете лицензионным положениям BSD, вы можете выбрать нужные функции замедления непосредственно из исходного кода jQuery UI. Обратите внимание, что некоторые из этих функций зависят от других функций в списке.

Чтобы просмотреть и сравнить эти функции замедления в действии, см .: http://api.jqueryui.com/easings/

Для тех, кто использует упаковщик, такой как Webpack, для объединения ресурсов, отображаемых на сервере, я столкнулся с ошибкой Error: TypeError: _jquery2.default.extend is not a function ( reference ). Я смог обойти это, используя Object.assign() вместо $.extend:

import $ from 'jquery'

// Extend jQuery easings with easeOutCubic
$.easing = Object.assign({}, $.easing, {
  easeOutCubic: (x, t, b, c, d) => {

    return c * ((t = t / d - 1) * t * t + 1) + b

  },
})

Существует плагин bez для jquery ( http://github.com/rdallasgray/bez ), который позволяет создавать пользовательские функции замедления Безье.

Если вы хотите поиграть с четырьмя параметрами Безье, вот онлайн-инструмент, в котором вы можете легко получить нужные параметры: http://cubic-bezier.com

Вот код
