The problem you describe above was addressed by Apple in iOS 9.3 and also in 
Safari 9.1 on Mac. That release changed the style of JavaScript alerts so that 
they are less likely to appear to come from Safari, the operating system, or 
Apple. They look more like part of a webpage, and no longer interfere with 
closing a tab or webpage, using the back button to leave the webpage, or using 
the smart search field to enter a new search or website address.

I don’t think that’s the same topic, though, as what this thread was originally 
about.

Hi,

Unlike others on this thread I'm a little more ordinary user of the web.
Came across one such modal just today!

So thank you for reporting this.

I wish to add that this issue is a bit more annoying on mobile: both on
iPad and iPhone. I guess the behavior on Android phones too will also be
the same, but this needs validation.

Once the webpage loads, it goes into a JS invoked confirm/ok modal that
would not relent -- not without seeking credit card info or something else
to let you off the hook. The site that I saw today was somehow phishing a
*.gov url too, using serious/ even scary warnings with quotes from Federal
Law / websites... :-)

The only way out then was to delete the browser from my iPad and reinstall
it clean.


Cheers,

Does 'hover' refer to modal dialog e.g., window.alert?
That is the only way I know that you can block a user to click back button.
Here is a simple page that does this: http://jsbin.com/fuwosaxefa

That behavior is a side-effect of how a browser may decide to implement
modal dialog which is dependent also on the OS. I tested a few browsers on
Linux & Mac and this is what I found:

*Mac*
Firefox, Chrome, Safari: Navigation buttons are usable while modal dialog
is shown.
*Linux*
Chrome: Navigation buttons are block while modal dialog is shown.
Firefox: Navigation buttons remain usable.
*Windows*


Perhaps this is worth a non-normative note in the spec in "user-prompt"

Agree.  

May it be done within the History API spec?  

Just wondering.

Last one I found is already taken down (I always report it to the ISP - 
often Amazon cloud)


What it does is make loud buzzing noises while flashing a message that 
your computer has been infected with a virus and you must call microsoft 
support immediately.


Only thing that works is closing the tab or quitting the browser.

It's effing stupid that anyone ever thought it was a good idea to let
JavaScript disable the standard browser controls. As browsers have done
that, it needs to be specified that JavaScript can't do that.
