Answer 1

<SCRIPT LANGUAGE="JavaScript">
var winWidth=340;
var winHeight=210;
var top = (screen.availHeight/2)-(winHeight/2);
var left = (screen.availWidth/2)-(winWidth/2);
window.open("22.htm","","toolbar=no,menubar=no,scrollbars=no,resizable=no,location=no,status=no,width="+winWidth+",height="+winHeight+",top="+top+",left="+left);
window.close;
</SCRIPT>

Answer 2

if(flag = undefined)
{
var objwin = window.open(window.location,window.name,"fullscreen=0,menubar=0,toolbar=0,location=0,directories=0,status=0,menubar=0,scrollbars=0,resizable=1,top=0,left=0",true);
objwin.flag = "opened";
}
//将窗口的工具栏、菜单栏等去掉，避免用户点击刷新按钮
win.document.oncontextmenu=function(){
return false
}
//屏蔽右键，避免用户使用右键菜单中的刷新
win.document.onkeydown=function(){
   if (win.event.keyCode==116 || (win.event.ctrlKey && win.event.keyCode==82)){
win.event.keyCode=0
win.event.cancelBubble=true
return false
}
}
//不相应F5和Ctrl + R的热键刷新
