SWFObject (originally FlashObject) is an open-source JavaScript library used to embed Adobe Flash content onto Web pages,〔Todd Perkins, (Search Engine Optimization for Flash ), O'Reilly Media, 2009, p. 87〕 which is supplied as one small JavaScript file.〔Yakov Fain, Victor Rasputnis, Anatole Tartakovsky, (Enterprise Development with Flex ), O'Reilly Media, Inc., 2010, p. 183〕〔(Source Checkout, swfobject - Google Code ), Page Header, overview of SWFObject〕 The library can also detect the installed Adobe Flash Player plug-in in all major web browsers, on all major operating systems (OS), and can redirect the visitor to another webpage or show alternate HTML content if the installed plug-in is not suitable.〔(SWFObject 1.5 Homepage ), deconcept〕 The library is independent, although related external libraries often integrate with it, such as SWFAddress for deep linking and SWFFit for dynamic content scaling. With the multitude of Flash embedding JavaScript libraries, SWFObject has emerged as the most popular being used by over 2,600,000 websites as of 2011,〔(SWFObject Usage Statistics ), BuiltWith〕 including high-profile websites such as Ask.com, Windows.com, Time.com, Skype.com, Discovery.com and YouTube.〔(Who uses SWFObject? ), SWFObject FAQ〕 ==Usage== SWFObject provides a reliable method of embedding Flash content into a webpage〔(Adobe Developer Network )〕〔Roger Braunstein, (ActionScript 3.0 Bible ), John Wiley and Sons, 2010, p. 898〕 by internally handling the various practices that one must follow in order for different web browsers to display Flash content correctly, and isolating them from the web designer. The developer may interface with the library in a standardized manner, the minimum being a single line of JavaScript code.〔(Embedding Adobe Flash Player content using SWFObject 2 - Documentation - Google Code )〕 Therefore, even inexperienced web designers without knowledge of the ideal HTML code to embed Flash content, can easily insert Flash content into web pages, and have them reliably work for the widest possible audience (excepting those with JavaScript disabled).〔Ben Henick, (HTML & CSS: The Good Parts ), O'Reilly Media, Inc., 2009, p. 195〕 Flash content inserted using SWFObject will also work on devices that support JavaScript execution (and Flash Player), such as the Wii, PlayStation 3 and Nokia N800, unlike the PlayStation Portable.〔(Do SWFs embedded with SWFObject 2 display in the Sony PS3 or Nintendo Wii web browsers? ), SWFObject FAQ〕 A disadvantage with SWFObject is that visitors with JavaScript disabled in their web browsers will not be able to view the Flash content,〔Chafic Kazoun, Joey Lott, (Programming Flex 3 ), O'Reilly Media, Inc., 2008, p. 524〕 and will instead see alternate HTML content provided by the web page.〔Eric Enge, Stephan Spencer, Rand Fishkin, Jessie C. Stricchiola, (The Art of SEO ), O'Reilly Media, Inc., 2009, p. 273〕 For websites that aim to reach the widest possible audience an alternate method is available, by using standards-compliant HTML markup to embed the Flash movie (typically using the 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「SWFObject」の詳細全文を読む スポンサード リンク
