unity3d Unity试图使下载的webGL游戏自动全屏[复制]

- 此问题在此处已有答案**：

Javascript request fullscreen is unreliable（5个答案）
14小时前关门了。
我从网上下载了一个Unity webGL游戏。我不知道它是用什么版本的Unity制作的。
它开始在一个小画布上播放与其他东西在页面上，如统一的标志，有一个按钮，使其全屏页面上。我希望它是全屏，只要你加载页面。
我试着在index.html的脚本中添加这一行，以单击全屏按钮。

fullscreenButton.click();

但是我得到了一堆错误。

这是一个完整的index.html，里面有javascript。你可以看到我在底部附近添加的行。我刚刚尝试在unityInstance. SetFullscreen（1）被赋给它的onclick事件（或者其他什么事件（我不知道关于web的任何事情）之后单击按钮。我还尝试调用unityInstance. SetFullscreen（1），但是我得到了同样的错误。那么我怎样才能让它全屏显示呢？
