Javascript 无法再次请求全屏显示
我有个问题。全屏请求在Firefox中运行良好，但在Chrome中，当我请求并取消全屏时，我不能再次请求它（F11工作）。此外，当我重新加载页面时，它会取消全屏显示Javascript 无法再次请求全屏显示,javascript,google-chrome,fullscreen,Javascript,Google Chrome,Fullscreen,我有个问题。全屏请求在Firefox中运行良好，但在Chrome中，当我请求并取消全屏时，我不能再次请求它（F11工作）。此外，当我重新加载页面时，它会取消全屏显示 jQuery('.fullScreen').click(function(){ var docElm = document.documentElement; if (docElm.requestFullscreen) { docElm.requestFullscreen(); } else

此外，当我全屏按esc键时，它会最小化，但我无法使用我的按钮返回全屏。好的，有几个想法 首先，当你按下退出按钮时，它不工作的原因。很简单，因为jquery没有被执行。要解决刷新问题，您可以放置一个cookie，说明浏览器是否处于全屏状态，如果处于全屏状态，您可以在page ready事件中将其设置为全屏状态。我想为你提出一个新的想法 下面是一个完全复制粘贴的全屏api演示 我想强调一个片段
fsElement.addEventListener(fullScreenApi.fullScreenEventName, function() {
if (fullScreenApi.isFullScreen()) {
fsStatus.innerHTML = 'Whoa, you went fullscreen';
} else {
fsStatus.innerHTML = 'Back to normal';
}
}, true);

FullScreenChanged事件–W3C和Webkit会在全屏显示的元素上触发FullScreenChanged事件，但Mozilla会在document对象上触发该事件。它在my Chrome（v 20）中正常工作。你能得到更多关于浏览器版本和你的工具如何最小化的信息吗（如果你不在F11前退出的话）？我在第一篇文章中添加了这个功能。我使用的是Chrome v22.0.1229.94 m。规格已更改
