Why trigger F11 press event doesn't work?

Question

I just read this question: Full Screen Page by pressing button instead of F11
The op asked to replace F11 with other hot keys, so I\'m wondering that maybe I

Answer 1

You won't be able to override the browser's built-in hotkeys from within a web page.

You might be able to do it in a browser extension, but that's would surely be serious overkill just to change the application's hotkeys.

In any case, why would you even want to override the standard keyboard shortcuts? I don't get that. They've been standard for a long time; most users will be familiar with them, and will find it very odd if they've been changed to something else.

Answer 2

Don't look at is as a question of "How do I trigger F11?" - look at is as "How do I trigger or simulate full-screen?"

With older versions of IE you can open a new window straight into full-screen:

window.open(someURLorOther, '', 'fullscreen=yes, scrollbars=auto');

Or you can use window.open to open a new window of a specific size.

Or you can try to resize the current window to fill the screen:

moveTo(0,0);
resizeTo(screen.availWidth,screen.availHeight);

However just because you can doesn't mean you should. You should never resize the current window - this annoys practically everyone. Opening a new window to a size you choose is more reasonable, though if it's too big it can be annoying, and on a normal web page (where by "normal" I probably mean not some kind of browser-based data-entry app) it is nicer not to open new windows.

Answer 3

You can not do this. The linked answer in that question provides a way with jQuery to simulate key-presses, within the jQuery event framework.

You simply can not trigger or fake keypresses. So the answer of this question is:

No, this is impossible

Answer 4

I think this is the one :) to detect it ...

$(document).keyup(function(e){
   if(e.which==122){
       e.preventDefault();//kill anything that browser may have assigned to it by default
       //do what ever you wish here :) 
       alert('F11 pressed');
       return false;
   }
});

but triggering it (NOT POSSIBLE)

But you will not prevent the browser from full screen :) ... Reson given is that , lets say I have full screened it somehow, and wish to toggle out of it using F11 but u are preventing me, I would have to restart PC, [computer illiterates] which poses security risk as you are preventing a user from doing something he is expecting to do, and they may think PC is broken or something :) so ...there you are.
