前言
JavaScript 自 1995 年推出至今，已從 Netsccape 瀏覽器裡的小程式，一路演變為高效
能的 JIT 解譯引擎。猶記得五年前，當 Ajax 與其獨樹一幟的黃褪技術（yellow fade
technique）甫推出時，還曾撼動整個 JavaScript 程式設計界。而如今，大夥早已對動輒
數千行的複雜 JavaScript 程式見怪不怪了。
到了去年，又誕生了一種嶄新概念的 JavaScript 網頁應用程式，雖說許多概念和操作模
式是沿襲自大眾熟習的桌面型應用程式，但對於網頁應用程式的使用者而言，這可說
是一種前所未見的操作體驗。過去操作網頁時一直要不斷等待載入新網頁的情景已不復
見。如今威力強大的 JavaScript 引擎，已大幅提昇用戶端程式的能力，不僅使得網頁提
供更即時的回應，也帶給了使用者更佳的操作體驗。
除了 JavaScript 引擎有長足的進步之外，CSS3 和 HTML5 規格也不斷納入許多新功能，
雖說 CSS3 和 HTML5 的規格至今仍未完全拍板定案，但大多數主流的瀏覽器都已經開
