Beside other stuff the main reason for this change is the circumstance that Firefox triggers the "Toggle RTL mode" shortcut if the user press F11 to switch Firefox into the fullscreen mode. Each browser sends keycodes that are used by different other keys on the keyboard for the function keys. Firefox is the only browser which sends the onkeypress event for the function keys. The used keyboard event properties event.keyCode and event.which are already marked as deprecated and has been removed from the Web standards. The "DOM Level 3 Events" standard specifies event.key as their successor. Right now event.key is only available for Firefox 29+ and Internet Explorer 9+. Webkit based browser have support for the former specified event.keyIdentifier. The implementation of event.keyIdentifier isn't the same across different webkit based browsers and buggy: - the value for the z key is F11 (Chrome - Windows, Linux) - the value for the F11 key is F11 as well on (Chrome - Windows, Linux) - the value for latin keys is always the value of the capital letter (Chrome) - the value for cyrillic keys depends on the shift modifier (Chrome) - the value for the keypress event is always an empty string (Safari - Mac OS) - the value for the keydown event matches the keyboard layout dependent character (Safari - Mac OS) - the value for the keydown event does NOT matches the keyboard layout dependent character (Chrome - Windows, Linux) Instead of workaround the problems, the event.which is used for every browser that doesn't support event.key. |
