Question

我编写了一个python-cgi脚本（raspberry），它在浏览器中显示了一些带有一些数据的页面。我将从浏览器中输入常用地址（//localhost/cgi-bin/myscript.py）的其他PC（linux，mac等）进入此页面。该页面将以全屏模式显示。我会在页面上有一个按钮，按下该按钮，页面将关闭并退出浏览器。我尝试使用pygame按钮并使用提交（发布或获取方法）按钮但没有成功（我不是真的很专业！）。有人可以帮帮我吗？感谢

你的问题不是Python的问题，它是一个JavaScript问题，就像@rob所说的那样，它与这个问题重复：stackoverflow.com/questions/2076299/...

并为你总结一下;你需要JavaScript来关闭窗口，但是当它发生时，JavaScript会被沙盒化，以防止它关闭页面上没有被同一个脚本打开的窗口，所以如果你打开一个标签或窗口浏览器并导航到一个页面，该页面不能自杀也不能杀死浏览器，它只能关闭并杀死它通过JavaScript启动的任何窗口。

您唯一能做的就是导航到不同的页面，例如在JavaScript中执行window.location = 'A DIFFERENT URL';您甚至可以导航到about:blank，在大多数浏览器上显示空白页。

怎么退出cgi？
