制作网页时,做了一个弹出窗口,IE9+/Chrome/Firefox都能将底层链接遮罩,但IE6/7/8不能遮罩,请问怎么办?
具体代码如下:

<!DOCTYPE html><html>  <head>	<style>	* {font-family:宋体; font-size:12px; border:0;}	</style>  	<script type="text/javascript">		function edit()		{						document.getElementById("shadow").style.visibility = 'visible';		}  	</script>  </head>  <body>  	<div id="shadow" style="text-align:center; visibility:hidden; position:absolute; left:0; top:0; width:100%; height:100%; background-color: rgba(0,0,0,0.5); z-index:100; border:0; overflow:hidden;">  		<div style="border:1px solid #57667d; background-color:#dfe8f6; top:50%; left:50%; width:502px; height:342px; margin:-171px 0 0 -251px; position: absolute; z-index:101; box-shadow:6px 8px 6px #666;" >  			<div style="float:right; margin-right:7px; margin-top:5px;"><a href="#" title="关闭" onclick="document.getElementById('shadow').style.visibility = 'hidden';">X</a></div>			<div id="editbox" style="width:100%; margin-top:30px;">我是弹出窗口,在IE6/7/8下不能遮罩住上面的超链接。请问怎么办?</div>		</div>  	</div>	<div id="content" style="width:100%; height:300px; top:80px; left:0; border:0; background-color:white; text-align:center; position:absolute; z-index:0;">	<a href="#" onclick="edit()">弹出窗口</a>  <a href="http://www.sina.com.cn">新浪网</a>	</div>  </body></html>

rgba这个透明不兼容,需要用特别的工具来处理掉。

弹窗出现后,仍然没有遮罩住“新浪网”这个链接,请再帮忙看看。(IE8测试)

IE 系仅在 IE8 测试

把 mask 放在 shadow 里最前面位置

    <div id="shadow">        <!--[if lte IE 8]><a id="mask"></a><![endif]-->        ...

只需给 shadow 设置一个足够大的 z-index 就行了, 其他的 z-index 都不需要了;

如果把 shadow 放在 body 的最后部, 在没有用其他 z-index 的情况下, shadow 也不用设置 z-index 了

3楼 用了一个 mask 是多余的, 只需要给 shadow 加上低版本 IE 专用的 CSS 就行了

5楼的代码在IE8下通过了,非常感谢!再请教一下,IE6下怎么办呢?

演示:  http://a7d.net46.net/dark_mask_for_IE.php
IE 6: height: 100%; 不支持;    a>b 选择器不支持.

以下代码 IE6 已测试通过.   IE7 没安装, 没做测试

<!DOCTYPE html><html><head><style>* {    font-family: 宋体;    font-size: 12px;    border: 0;    margin:0;    padding:0;}#shadow {    text-align: center;    visibility: hidden;    position: absolute;    left: 0;    top: 0;    width: 100%;    height: 100%;    _height:expression(document.documentElement.clientHeight+"px"); /* for IE6 */       background-color: rgba(0, 0, 0, 0.5);    border: 0;    overflow: hidden;}#diagbox {    border: 1px solid #57667d;    background-color: #dfe8f6;    top: 50%;    left: 50%;    height: 342px;    width: 502px;    margin: -171px auto auto -251px;    position: absolute;    box-shadow: 6px 8px 6px #666;}#x_btn {    float: right;    margin-right: 7px;    margin-top: 5px;}#editbox {    width: 100%;    margin-top: 30px;}#content {    width: 100%;    height: 300px;    top: 80px;    left: 0;    border: 0;    background-color: white;    text-align: center;    position: absolute;}</style><!--[if lte IE 8]><style>#shadow {    background-color: black;    filter:Alpha(Opacity=50);}</style><![endif]--></head><body>    <div id="content">        <a href="#" onclick="edit()">弹出窗口</a>        <a href="http://www.sina.com.cn">新浪网</a>    </div>    <div id="shadow">        <div id="diagbox">            <div id="x_btn">                <a href="#" title="关闭" onclick="shadow.style.visibility = 'hidden';">X</a>            </div>            <div id="editbox">我是弹出窗口,在IE6/7/8下不能遮罩住上面的超链接。请问怎么办?</div>        </div>    </div></body></html><script type="text/javascript">    function edit() {        shadow.style.visibility = 'visible';    }</script>

neorobin,真牛! IE6/8都成功了!IE7虽然有点问题,但基本不影响了。对了,请教一下,我是用ieTester测试的,可以吗?

我没有用过 IETESTER, 搜了下, 微软自己也提供了一个  https://www.modern.ie/zh-cn,  还有个与它合作的 BrowserStack. 收费的, 我觉得开发完成前可以用下这些虚拟的浏览器软件或者服务, 到最后还是在实机真实浏览器上跑最有保证
