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 ;
}

</ script >


无边框窗口代码
//第一步:把如下代码加入
< head ></ head > 区域中
< script language =javascript >
minimizebar
= " minimize.gif " ; // 视窗右上角最小化「按钮」的图片
minimizebar2 = " minimize2.gif " ; // 滑鼠悬停时最小化「按钮」的图片
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。
scr:是否出现卷轴。取值yes/no或者1/0。
