请问如下网站的效果（可以挡住一切的层），怎么作的（直接说，就要是代码）。重金１００分重金１００分

麻烦高手了。我新人，help me

这个效果以前在CSDN上也有人问过
搞一DIV 整屏的点击按钮后设置 DIV可见再设置透时度属性再试试

就是这个方法啦
function showLoginBox(urlvalue) {
var lp = document.getElementById("layerpoint");
var lpt = document.getElementById("layertable");
var mask = document.getElementById("mask");
var url = document.getElementById("url");
url.value = urlvalue;
lpt.style.top=document.body.scrollTop+ (browserHeight()-360)/2;
lpt.style.left=(browserWidth()-660)/2;
mask.style.display='';
mask.style.width = document.body.scrollWidth;
mask.style.height = document.body.scrollHeight;
lpt.style.display='';
lp.style.display = '';
}

.ContextMenu{
    height:160px;
    width:120px;
    background-color:#f6f6f6;
    font-family:Trebuchet MS,Verdana,Arial,sans-serif;
    font-size:8pt;
}
.ContextMenuItem{
    height:16px;
}
.ContextMenuItemHover{
    background-color:#e1e1e1;
    background-image:url(../../styles/office2007black/webmenu/igmenuitemhover.jpg);
    cursor:pointer;
}  function ShowContextMenu(evt){
        //Firefox passes event arg as parameter (evt).  If that is null, we'll use window.event (Internet Explorer proprietary)
        var e=evt?evt:window.event;

        //Call show menu with menuID
        //specify clientX and clientY to get more accurate positioning for this particular layout
         igmenu_showMenu("<%=this.CopyPasteMenu.ClientID %>",null,(e.clientX+document.documentElement.scrollLeft)+"px",(e.clientY+document.documentElement.scrollTop)+"px");

        //Firefox (W3C) - cancel event
        if(typeof(e.preventDefault)=="function")e.preventDefault();
        //InternetExplorer (Proprietary) - cancel event
        e.returnValue=false;
        return false;
    }

昨天发现一个可能的挡住的。在这个基础上再实现个人的作法比较好

</div>这是我们网站上实现的代码  你可以参考一下~  效果和那个一样~

要盖住 select ActiveX 之类的，需要使用 iframe 或者 window.popup 之类的

根本不可能，有挡住任何东西的层，一般如ＤｒｏｐＤｏｗｎＬｉｓｔ等控件都是挡不了。========================================谁说挡不住?我的就可以挡住.^_^

主要是在弹出的div层下面生成一个iframe托住div，这样div下面就算有炸弹，也能挡住了

这个应该可以满足LS的要求。你可自己看里面的源码。我前段时间也研究了哈。

我还以为是什么呢，用的是div作弹出登陆页面，背景是用样式中的透明色控制的

ＤｒｏｐＤｏｗｎＬｉｓｔ是遮不了的.
// JScript 文件
    //激活层
    function Show()
    {
document.getElementById("divmain").style.display='';
NGShieldDIV();
    }//屏蔽操作
function NGShieldDIV()
    {
    if(document.body.clientHeight>screen.height-120)
    {
    DIVheight=document.body.clientHeight;
    DIVwidth=document.body.offsetWidth;
    }
else
    {
    DIVheight=screen.height;
    DIVwidth=document.body.offsetWidth;
    }
        var str="<div id='LoginWinDIV2' oncontextmenu='event.returnValue=false' class='ShieldWinDIV' style='width:"+DIVwidth+";height:"+DIVheight+";'></div>";
    ShieldWinDIV.innerHTML=str;
    }CSS
.ShieldWinDIV {
position:absolute;
left:0px;
top:0px;
background-color: #0D1426;
filter:progid:DXImageTransform.Microsoft.Alpha(opacity=70);
z-index:98;
}

HTML
<span id="divmain" style="DISPLAY: none">
<div class="LoginWinDIV" id="LoginWinDIV" style="PADDING-RIGHT: 1px; PADDING-LEFT: 1px; Z-INDEX: 99; LEFT: 300px; PADDING-BOTTOM: 1px; WIDTH: 456px; PADDING-TOP: 1px; POSITION: absolute; TOP: 150px; HEIGHT: 446px"></DIV></SPAN>
<span id="ShieldWinDIV"></span>

只有octverve(生命无色，命运多彩……) ( ) 信誉：100 是真能遮挡住的虽然背景颜色不好看，不知道在哪里改。

楼主给我100分哦,呵呵,直接把我的代码复制粘贴成html文件就可以了
我是从你给的网页上分析、精炼出来的<html>
<head>
<title>用内嵌框架遮住整个页面演示</title>
<script language="JavaScript" type="text/JavaScript">

</script>
</head>
<body>
<p>
<input id="B1" type="button" value="点我遮住整个页面" onclick="javascript:Mask(); alert('点 [确定] 恢复页面'); Unmask();">
