这个API很有用。 这里顺便发一下我的fullscreen的兼容脚本(window.fullScreen属性和fullscreenchange事件)。 if (!('fullScreen' in window)) Object.defineProperty(window, 'fullScreen', { get: function() { return (screen.width == window.outerWidth && screen.height == window.outerHeight) } }) var _fullScreen = window.fullScreen if (!('onfullscreenchange' in window)) window.addEventListener('resize', function() { var f = window.fullScreen if (f != _fullScreen) { _fullScreen = f fireSimpleEvent('fullscreenchange', document, {bubbles:true}) } }, false) function fireSimpleEvent(type, target, option) { if (!target) target = document if (!option) option = {} var evt = document.createEvent('Event') evt.initEvent(type, !!option.bubbles, !!option.cancelable) return target.dispatchEvent(evt) } fullscreen应用实例:我自己的演讲slides都是用HTML5的,在全屏时进入slides状态。例子见: http://hax.github.com/2011/es5_safety/ ,Chrome/FF中按F11可以看到效果。 2011/8/5 Zi Bin Cheah <zibin@opera.com> > 全屏对HTML5 apps发展应该是很重要的,**apps如果没法控制全屏就没有办法达到native的效果,** > 比方html5游戏还是给人网页的感觉,而非一个game。 > > Mozilla提出了Fullscreen API[1],webkit也会使用它[2]。 > > 比方调用video全屏 > > <video src="pelican.webm" autoplay > onclick="event.target.**requestFullScreen()" > onended="document.**cancelFullScreen()"> > </video> > > 最大的隐忧是全屏是否应该得到用户的允许下才能进行(**explicit permission),而且也存在这其他安全问题。 > > > [1]https://wiki.mozilla.org/**Gecko:FullScreenAPI<https://wiki.mozilla.org/Gecko:FullScreenAPI> > [2]http://lists.whatwg.org/**htdig.cgi/whatwg-whatwg.org/** > 2011-May/031538.html<http://lists.whatwg.org/htdig.cgi/whatwg-whatwg.org/2011-May/031538.html> > > > >
