TimelineLite建⽴立⼀一系列的動畫效果 (animation sequences)
使⽤用 TimelineLite 的實例來儲存多個動畫 ( thousands of animations)
將多個動畫群組化 (group)
並視為 single tween 來控制
可將 playback control 使⽤用於 Timeline 群組

技術⾯面有對基礎的 element 做 reset
➡ html, body, div, span ...
沒有對不同的瀏覽器與裝置做 “base”
➡ 請參考第⼀一堂課介紹
➡ Cross browser and cross devices
使⽤用 “px” 較不合適
➡ 請參考第⼀一堂課介紹
➡ 改⽤用 “rem” 等較合適的單位

總結使⽤用 Media Query 做為⼋八屏的基本技術
不需從新寫起,但要了解其原理 (第⼀一堂課)
使⽤用現有的 UI Framework (如 Less Framework 4)
以 Less Framework 4 為例,有些⼋八屏 (cross devices) 的技術細節未考慮到

改⽤用 jQuery Media Query
➡ 取代 CSS Media Query
➡ 以克服課堂所提的問題

總結“reset” + “base” 將成為 cross device 的重要技術
⼤大部份 UI Framework 都會進⾏行 “reset”
“base” 部份⺫⽬目前仍需由開發者⾃自⾏行處理

Prototype 的技術⾯面基於 JavaScript 的 Prototype 觀念
➡ JavaScript OO
直接在瀏覽器與 HTML DOM 裡⾯面加⼊入功能 (methods)
擴充 element 的原貌 (prototype)
與 jQuery pattern 有何不同?
➡ 延續第⼀一堂課

JavaScript 的 Prototype每個 JavaScript 物件都有⼀一個 “prototype” 屬性
JavaScript 引擎的實作並不提供 class 觀念
➡ 延續第⼀一堂課的觀念
➡ 使⽤用 function() 來表⽰示 class,再使⽤用 “new” 來取得 instance
➡ Constructor pattern 與 Factory method pattern
➡ 上述做法,class 並不具備 OOP (C++/Java) 的必要特性
因此,使⽤用 JavaScript 的 “prototype” 來模擬 class 的 OO 特性

Class 宣告 & Instance
function Person(name, job) { this.name = name; this.job = job; this.queryJob = function() { alert(this.job); };} var person = new Person("Jollen", "Software Developer");person.queryJob();

定義 Functional Object
var Person = function (name, job) { this.name = name; this.job = job; this.queryJob = function() { alert(this.job); };}; var jollen = new Person("Jollen", "Software Developer");
jollen.queryJob();

動態加⼊入新的 Methodvar Person = function (name, job) { this.name = name; this.job = job; this.queryJob = function() { alert(this.job); };};
Person.prototype.getName = function () { return this.name;}
var jollen = new Person("Jollen", "Software Developer");
jollen.queryJob(); // “Software Developer”jollen.getName(); // “Jollen”

改變的是 Prototype (Class)var Person = function (name, job) { this.name = name; this.job = job; this.queryJob = function() { alert(this.job); };};
var jollen = new Person("Jollen", "Software Developer");
// 順序交換不改變其結果Person.prototype.getName = function () { return this.name;}
jollen.queryJob(); // “Software Developer”jollen.getName(); // “Jollen”

什麼要學 JavaScript PrototypePrototype 改變的是 “base object”
DOM 裡有許多 Function Object (class)
➡ 如何改變其 base object ?
使⽤用 JavaScript “prototype” 屬性
更簡單 “extend DOM’ 的⽅方式
➡ 使⽤用 prototype.js

關於 Prototype.jsPrototype provides functions to make HTML DOM programming easier
Like jQuery, Prototype has its $() function
The $() function accepts HTML DOM element id values (or DOM elements), and adds new functionality to DOM objects
Unlike jQuery, Prototype has no ready() method to take the place of window.onload(). Instead, Prototype adds extensions to the browser and the HTML DOM

Prototype.js 範例<div id="watch"></div><script>var w = document.getElementById("watch");w.setAttribute(); // OK. DOM Element 裡的 method
// Prototype.js 的官方範例var MyUtils = { truncate: function(element, length){ element = $(element); return element.update(element.innerHTML.truncate(length)); }, updateAndMark: function(element, html){ return $(element).update(html).addClassName('updated'); }}; Element.addMethods(MyUtils); // Prototype.js 擴充 DOM
$('watch').truncate(100); // OK. 使用 Prototype 擴充了 Element$('watch').helloWorld(); // OK.w.helloWorld(); // OK. 呼叫 DOM</script>

關於 Drag and DropHTML5 的正式標準
可⽀支援任何的 Element
直接實作
或使⽤用 jQuery UI 更為⽅方便
➡ 可將任何 Element 設定為 Draggable

實作 Taget 的 onDrop() 事件<script>function allowDrop(ev){ ev.preventDefault();}
function drag(ev){ ev.dataTransfer.setData("Text",ev.target.id);}
function drop(ev){ ev.preventDefault(); var data=ev.dataTransfer.getData("Text"); ev.target.appendChild(document.getElementById(data));}</script>
Source: http://www.w3schools.com/html/html5_draganddrop.asp
prevent the browser default handling of the data (default is open as link on drop)(任何的 event callbacks 都有其 default 處理方式)

JavaScript UI FrameworkWhat’s the different between…
jQuery
- Is a way to find stuff on a page and work with that stuff.
- Write less, do more, a JavaScript library.
jQuery UI
- Is a UI library that works with jQuery. (need jQuery)
jQuery Mobile
- Is a UI library for Mobile devices that works with jQuery as well. (need jQuery)

Zepto (not fully support IE)
Xui
jqmobi / jqui
Use Cases :
jQuery + jQuery UI
jQuery + jQuery Mobile
Zepto/jQuery + jQTouch
jQuery/Zepto/Xui + Custom UI
Sencha Touch (commercial)
How about use all of these…
