html5叫板flash,革命在即?

2010年4月30日,对it行业来说是一个特别的日子,因为这一天苹果ceo乔布斯宣布iOS弃Flash,在iphone新版设备上将不再对flash提供支持,将用html5技术来代替。ios将全面采用HTML5的消息传出后,微软也力挺乔布斯,称Flash落后。乔布斯封杀Flash的理由是:Flash不适合触摸设备,技术封闭且落后。而HTML5可以通过代码实现Flash视频播放技术,且支持Canvas画布功能。所以就长远的发展来讲。用户会慢慢接受html5技术。

这枚消息无异于重磅炸弹。消息一出,不止震惊了it业界人士,同样还波及到普通用户。根据相关机构调查Flash Player的市场份额将近98%,普及率高,受众广。苹果公司在2010年相继推出iPhone 4与iPad,因外观时尚、灵动、便携而广受欢迎,而iOS封杀Flash的举动,也让用户与开发者重新对HTML5有了初步了解。在iTunes商店中的应用不见Flash,让那些基于Flash技术的游戏编写者不得不更换为HTML5。事实证明,HTML5在iOS平台深受好评,但有些用户还是希望能出现一款具备Flash特色的iOS游戏。


有了苹果、谷歌这2大互联网巨头的力挺,HTML5开始解开它神秘面纱,可谓众星捧月,迅速受到与开发者的垂青。谷歌、苹果都赞其为网络标准新生力军;连一向喜好特立独行的微软,也悄然在Internet Explorer 9 中加入对HTML5的大量支持(IE10的HTML5得分更高于IE9),今年微软的开发者大会上不仅推出了Windows 8,同时还宣布将取消Metro界面下Flash支持。那么Flash是否会被HTML5搞死?或是与HTML5并存而生?处于尴尬位置的Adobe,将采用什么手段与HTML5抗衡?

简单了解一下HTML5:  

根据维基百科上的解释,HTML5的前身是Web Applications1.0,源自于WHATWG。
2007年,它被互联网联盟W3C接纳。HTML 5与HTML 4的不同之处  
增加新的元素:section, video, progress, nav, meter, time, aside, canvas  
input元素的新属性:日期和时间,email, url  
新的通用属性:ping, charset, async  
全域属性:id, tabindex, repeat  
移除元素:center, font, u, strike, s, frameset, frame, applet

HTML 5技术优势  

据一位参与html5标准制定的开发者说,“HTML5与Flash在功能上并不完全重叠的,比如对于摄像头等计算机硬件的调用,仍然只能使用Flash或其他方法实现”。
但HTML5引入了一些足以让Flash致命的元素,最致命的两个标签:canvas与video。  
一旦新网络标准只采纳HTML5的Video,这将导致我们所登录的视频网站统一放弃Flash Video(FLV),对flash的市场占有率形成致命冲击。此举将深刻影响到整个互联网,而Canvas也将网络动画与图片载入速度大大提升。希望这次变革能给广大网民带来前所未有的畅快感受。。。
