关闭在 web 浏览器上运行的脚本后如何关闭命令行 window？

Question

I am running a dash application through cmd and after closing the web browser (https//127.0.0.1/8050) on which the dash application is running, I want to close the command line window from where the program was initially run. Any idea how to do that?

You will need to write a small javascript function for this. So first when the application is started from your command line, get process id of the process that gets started, and pass this to a variable in dash. There are many ways of retrieving this process id.

Then an event listerner in javascript like so:

window.addEventListener('beforeunload', function (e) {
    e.preventDefault();
    e.returnValue = '';
});

Finally in add a kill event using the process id you have collected at the start

GetObject("winmgmts:").Get("Win32_Process.Handle='" + pid + "'").Terminate();

Here is the documentation for adding extra js to the dash application.
