我正在尝试使用 javscript 获得全屏模式。所以我找到了this回答并处理它。但我发现，当我使用此代码 触发全屏时，滚动条消失并且滚动被禁用。但是，如果我使用 F11 触发相同的操作，则会出现滚动条并且可以滚动。
我曾尝试将 overflow:auto 提供给正文，但它没有任何效果。 Here是重现同一问题的 fiddle 。当您运行 fiddle 时，您将能够看到所有段落都不可见。
注意:我使用的是 Firefox 45。
HTML :
<body>
<input type="button" value="click to go fullscreen" onclick="requestFullScreen()">
<p>
1 some text to make screnn bigger

Javascript:
function requestFullScreen() {
var el = document.body;
// Supports most browsers and their versions.
var requestMethod = el.requestFullScreen || el.webkitRequestFullScreen || el.mozRequestFullScreen || el.msRequestFullScreen;
if (requestMethod) {
// Native full screen.
requestMethod.call(el);
} else if (typeof window.ActiveXObject !== "undefined") {
// Older IE.
var wscript = new ActiveXObject("WScript.Shell");
if (wscript !== null) {
wscript.SendKeys("{F11}");
}
}
}
最佳答案
将 el 更改为 document.documentElement 滚动将在 Firefox 中工作。
var el = document.documentElement;
它会在使用 Chrome 时在 JSFiddle 中中断(我猜是因为 iframe 策略)，但我认为这不是主要用途。
