JavaScript如何实现IE全屏？
window.open(url, name, "fullscreen=yes")
但是 fullscreen 这个Window functionality feature不要用：
Do not use. Not implemented in Mozilla. There are no plans to
implement this feature in Mozilla. This feature no longer works in
MSIE 6 SP2 the way it worked in MSIE 5.x. The Windows taskbar, as well
as the titlebar and the status bar of the window are not visible, nor
accessible when fullscreen is enabled in MSIE 5.x. fullscreen always
upsets users with large monitor screen or with dual monitor screen.
Forcing fullscreen onto other users is also extremely unpopular and is
considered an outright rude attempt to impose web author's viewing
preferences onto users. Note on fullscreen Supported in: Internet
Explorer 5+ fullscreen does not really work in MSIE 6 SP2.
window.open打开当前窗口大小的窗口 可以设置的
查一下window open，不知道行不行
window.open(document.location, 'big', 'fullscreen=yes')
