Is it possible to close IE in Kiosk Mode without a comfirmation alert?

Question

I can open a Chrome browser window in kiosk mode from the command line...

start chrome --kiosk "http://example.com/"

...and then close the page with a <button> that simply runs window.close(); in a JavaScript event.

But when I start IE in kiosk mode...

start iexplore -k "http://example.com"

...and click the same button, I get the alert:

The webpage you are viewing is trying to close the window. Do you want to close this window? [Yes /No]

Is there some way -- maybe with JavaScript or IE command line options -- to avoid the alert and get IE to act the same as Chrome?

Answer 1

Have your javascript function do this:

window.open('','_self').close()

Explanation: IE won't let you close, without warning, a window you didn't open. This function opens a blank window that overwrites the current window. And since you now own it, the next part of the function closes it without issue.
