string getPageNumber()
getPageId
string getPageId()
goToPage
boolean goToPage(pageNumber)
參數：
string, number pageNumber - 要轉到的頁面編號。
goToPageId
boolean goToPageId(pageId)
參數：
string pageId - 要轉到的網頁專屬 ID。
isLoaded
boolean isLoaded()
如果使用 load 成功以指定書籍初始化檢視器，則傳回 true。
影片簡介
highlight(opt_string)
參數：
string opt_string - 要醒目顯示的字串。如果是 null 或 undefined，則會關閉醒目顯示功能。
load
load(identifiers, opt_notFoundCallback, opt_successCallback)
參數：
string, Array of strings identifiers - 預覽網址或書籍 ID，例如 ISBN、OCLC 等。請參閱動態連結要求格式。如要為書籍指定多個替代 ID (例如精裝書和平裝書的 ISBN)，請傳遞這些 ID 字串的 Array；觀眾將會載入陣列中的第一本可嵌入的書籍。
Function opt_notFoundCallback - 如果 identifier 是書籍 ID，則在找不到書籍時會呼叫這個回呼。如果傳遞 null 或省略這個參數，系統就不會在失敗時呼叫任何函式。
Function opt_successCallback - 如果檢視器已成功以特定書籍例項化，且已準備好接收 nextPage 等函式呼叫，系統就會執行這個回呼。
