There are two javascript ways to view web site in full screen mode in IE:
1. window.open('http://www.sina.com.cn','','fullscreen')
Note: If view the page remotely, this way will ineffective, and you can use the second one instead.
2. var wsh=new ActiveXObject("wscript.shell");
wsh.run("iexplore -k http://www.google.com");
