第十六章
我們通常會使用下列多重視圖機制之一：
• Tab 導覽（頂部或底部）。
• 用來後退的頂部工具列與∕或後退鍵處理程式，如果可行的話。
• 使用按鍵或觸控分頁來循序檢視（如同投影片）。
版面配置
雖然我們只有使用一種 Web App 平台，仍然需要支援各種不同的螢幕大小、方向模式，
與物理螢幕大小。我們需要決定使用固定或流動設計，或響應式 Web 設計。
輸入方法
我們在設計行動網站時，也會出現這個問題：我們的 Web App 所處的設備具有各式各樣
的輸入方式（觸控、鍵盤、觸控板等等），因此必須以程式碼來支援所有輸入法，或許
也需要在觸控設備上改變版面配置（對於較大的元件）。
One-View Widget
one-view widget 是我們可以創建的 Web App 之中最簡單的一種（有時也是最強大的）。
它通常會有一個資訊畫面，而且可以選擇加入第二個畫面來設置主畫面的內容。它適合
用於氣象、金融、社群網路、新聞，與企業指示器（corporate indicator）。
動態應用程式引擎
因為 JavaScript 是一種動態語言，我們可以輕鬆地執行伺服器收到的程式碼（使用
eval()
或 JSONP 請求），因此，可以輕鬆地建立一個只有小型的引擎（如同網頁瀏覽
器）的 Web App，以它來接收伺服器的指令。
你可以從伺服器傳送所有程式碼（包括可在一些平台上存取私用 API 的程式），並且選
擇在本機持久存放區之中快取。因此，我們可以建立一個自行更新的 widget 機制，不需
要使用者介入即可接收最新版的應用程式。 ...
