问题
I have a script on page that will close the web page but when it does that I am getting this pop up message “the web page you are viewing is trying to close the tab. Do you want to close this tab?”
I want to suppress this message. I am using IE and done following settings In IE Tools/Internet Options/Security/(select) Internet Zone> (click) Default Level.
Or, Internet Options>/Security> (select) Internet Zone> Custom> Scripting> Active scripting> Enable. Both the settings didn’t worked for me and I am still getting the message. How can I prevent this?

The webpage you are viewing is trying to close this window warning in Internet Explorer
This is a old question and in the awnsers also lays your awnser i quote:
"Javascript can close a window if a javascript code opens it."
Otherwise, it can't. It is just a security feature. I hope i helped :)

There are some interesting workarounds on this question, basically revolving around inserting a window.open() somewhere into the sequence.
Bypass IE "The webpage you are viewing..." pop up
