I want to close the screen when I press the button on asp.net (VB).

I opened the screen I created on asp.net(VB) in safari on my iPhone.
I would like to delete the tab when I press the "Exit" button."
"When I press the button, a window appears and says ""Exit"" but
" "When I press ""Close"", the tab does not disappear, and I just return to the original screen."

Designer side programs

<div>
<asp:Button ID="btn_terminate" runat="server" Text="Exit" CssClass="button_shared_preference"/>
</div>

Code Side Programs

Protected Subbtn_terminate_Click (sender As Object, eAs EventArgs) Handles btn_terminate.Click
        ClientScript.RegisterClientScriptBlock(Me.GetType(), "key", "window.alert('Exit''); window.close(), True)
    End Sub

Here is the general flow of the work.
1. Access the site by loading QR with URL with iPhone camera
　　No special action is taken when loading the site
2. Check and input within the site
　　*It's not important, so I'll skip the details.
3. Press the "Exit" button to export the contents to the server and close the displayed window
　　The window you see is a site that you accessed with "1" and you ran through with "2".
"The problem is the ""Close Window"" part.
Export to the server has been implemented.

Don't you know what will happen with iPhone Safari or something like that, but don't you usually close it with a browser like that kind of script? JavaScript should only be able to close windows open in JavaScript.

I understand that it is probably the same as entering the URL of the page in question in the address bar of the browser and making a GET request.If that's the case, in the article introduced by Kunif in the question section,

window.open('about:blank','_self').close();

There seems to be no other way, but whether or not it can be closed as expected depends on the browser.I don't know what will happen with iPhone Safari because I don't have that environment.Why don't you give it a try?

By the way, I tried it in my environment, but only IE11, Firefox 97.0.1 was closed.

Chrome 98.0.4758.102, Edge 98.0.1108.56, Opera 84.0.4316.14 seem to ignore the close, leaving open about:blank.

If you can't use the above script in Safari on your iPhone, I recommend that you give up such a back-to-back approach and think about it in a direct way so that users can manipulate and close it themselves.
