如何去掉ie里面的关闭按钮,和屏蔽ALT+F4

去掉关闭按钮 可以使用无边框窗口设计,不过IE6中已经不支持了。。。
< script  language =javascript >
minimizebar
="ftp/minimize.gif"; '最小化图片路径
minimizebar2
="ftp/minimize2.gif"; '点击最小化图片路径
closebar
="ftp/close.gif"; '关闭图片路径 
closebar2
="ftp/close2.gif"; '点击关闭图片路径 
icon
="ftp/icon.gif"; '右边icon图片路径

你在您的link中要这样写
onclick="noBorderWin('xxx.asp','宽','高','#000000','#333333','#CCCCCC','名字','yes')"


屏蔽Alt+F4等快捷键:
< script >
function KeyDown()//屏蔽鼠标右键、Ctrl+n、shift+F10、F5刷新、退格键
 //alert("ASCII代码是:"+event.keyCode);
  if ((window.event.altKey)&&
      ((window.event.keyCode
==37)||   //屏蔽 Alt+ 方向键 ←
       (window.event.keyCode==39))){  //屏蔽 Alt+ 方向键 →
     alert("不准你使用ALT+方向键前进或后退网页!");
     event.returnValue
=false;
     }

  
if ((event.keyCode==8)  ||                 //屏蔽退格删除键
      (event.keyCode==116)||                 //屏蔽 F5 刷新键
      (event.keyCode==112)||                 //屏蔽 F1 刷新键
      (event.ctrlKey && event.keyCode==82))//Ctrl + R
     event.keyCode=0;
     event.returnValue
=false;
     }

  
if ((event.ctrlKey)&&(event.keyCode==78))   //屏蔽 Ctrl+n
     event.returnValue=false;
  
if ((event.shiftKey)&&(event.keyCode==121)) //屏蔽 shift+F10
     event.returnValue=false;
  
if (window.event.srcElement.tagName == "A" && window.event.shiftKey) 
      window.event.returnValue 
= false;  //屏蔽 shift 加鼠标左键新开一网页
  if ((window.event.altKey)&&(window.event.keyCode==115))//屏蔽Alt+F4
      window.showModelessDialog("about:blank","","dialogWidth:1px;dialogheight:1px");
      
return false;}

}

function Showhelp(){
 alert(
"Wrong!");
 
return false;
}

无边框窗口代码

closebar="close.gif"//视窗右上角关闭「按钮」的图片 
closebar2="close2.gif"//滑鼠悬停时关闭「按钮」的图片 
icon="icon.gif"//视窗左上角的小图标 

function noBorderWin(fileName,w,h,titleBg,moveBg,titleColor,titleWord,scr) //定义一个弹出无边视窗的函数,能数意义见下面「参数说明」,实际使用见最後的实例。 
/* 
------------------参数说明------------------- 
fileName :无边视窗中显示的文件。 
w     :视窗的宽度。 
h     :视窗的高度。 
titleBg :视窗「标题栏」的背景色以及视窗边框颜色。 
moveBg :视窗拖动时「标题栏」的背景色以及视窗边框颜色。 
titleColor :视窗「标题栏」文字的颜色。 
titleWord :视窗「标题栏」的文字。
