点击使浏览器全屏

javascript/jquery onClick make browser go Fullscreen

本文关键字：浏览器更新时间：2023-09-26

我正在寻找一种创建按钮的方法，当单击它时浏览器应该全屏显示。*这应该是按钮。

请，有什么想法吗?

我发现了这个类似的帖子，我想这是解决方案!但我会回来以后这个问题，希望有人有一个新的解决方案!

你不能。没有办法自动切换到全屏。相反，你可以指示/请求你的用户按F11手动全屏，但它应该是可选的。

好吧，这是我发现的，它工作，但不确定跨浏览器支持!

<div id="specialstuff" style="display: none;">
    </p><p>Status: <span id="fsstatus" class="fullScreenSupported">Back to normal</span></p>
</div>
<input type="button" value="Go Fullscreen" id="fsbutton">
