在Safari 5.1.2中传递Element.ALLOW_KEYBOARD_INPUT时，webkitRequestFullScreen失败

Question

Running into the following problem specifically in Safari 5.1.2 when attempting to use the javascript fullscreen api.

By copy and pasting the following lines into your browser on a loaded page, you can see the effect.

This works in Chrome 15 and Safari 5.1.2:

 javascript:document.querySelector('body').webkitRequestFullScreen();

This works in Chrome 15 but fails silently in Safari 5.1.2:

 javascript:document.querySelector('body').webkitRequestFullScreen(Element.ALLOW_KEYBOARD_INPUT);

ALLOW_KEYBOARD_INPUT seems like it should work in Safari, according to documentation here: http://developer.apple.com/library/safari/#documentation/WebKit/Reference/ElementClassRef/Element/Element.html

Any ideas why this isn't working?

Answer 1

This is known Safari bug. It can be sniffed during full screen switching:

someElement.webkitRequestFullScreen(Element.ALLOW_KEYBOARD_INPUT);
if (!document.webkitCurrentFullScreenElement) {
    // Element.ALLOW_KEYBOARD_INPUT does not work, document is not in full screen mode
}

Use this real time sniffing and thus your code will support future fixing bug in Safari.

Answer 2

someElement.webkitRequestFullScreen(Element.ALLOW_KEYBOARD_INPUT) works in chrome.

And someElement.webkitRequestFullScreen() works in safari 5.1.7

All test base on windows 7.

Answer 3

I just ran into the same issue, and this is most definitely a bug.

This may be a case of the Undetectables . Guess we're gonna have to use good ol' browser sniffing.

...(/Safari/.test(navigator.userAgent) ? undefined : Element.ALLOW_KEYBOARD_INPUT)

[edit] ...in which case keyboard input isn't possible. So I guess it's best to cut out fullscreen mode in Safari for the time being [/edit]

_{Keep in mind that the fullscreen API is in a very early stage at the moment, and should not be used in production}
