After the data is saved, the webpage is not closed_html/css_WEB-ITnose

The process is like this: after the data is saved, refresh and close actions are performed

Now the data has been saved
but the web page is not closed

window.opener.location = window.opener. location;
window.close();

Is it possible that window.opener.location = window.opener.location; is problematic? ?
Normally it is ok
The error occurred because multiple different page windows were opened. Could this be the reason?

Thank you

Can any expert help me analyze the possible reasons?

The error is open Multiple different page windows

What does this mean?

Is there any error in js?

The normal situation is correct

Occasionally the window does not close
In addition, there are many other pages opened

Could it be related to this?

Is there any error in js?

Because this happens occasionally,
so I can’t debug it, and I don’t know if JS reports an error.

Occasionally, the window is not closed.
In addition, many other windows have been opened. Could the page
have something to do with this?

Does anyone know?
