IE8 pop-up window cannot mask the underlying link, what should I do? _html/css

When making a web page, I created a pop-up window. IE9/Chrome/Firefox can mask the underlying link, but IE6/7/8 cannot. What should I do?
The specific code is as follows:

<!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>

Place mask at the front of shadow

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

Copy after login

Just set a z-index large enough for shadow, and other z-indexes are not needed;

If the shadow is placed at the end of the body, without using other z-index, there is no need to set the z-index for the shadow

On the 3rd floor, using a mask is redundant, you only need to set the shadow Just add the CSS specific to the lower version of IE

To neorobin:

The code on floor 5 passed under IE8, thank you very much! Let me ask you again, what should I do under IE6?

Demo: http://a7d.net46.net/dark_mask_for_IE.php
IE 6: height: 100%; Not supported; a>b selector is not supported.

The following The code IE6 has been tested and passed. IE7 has not been installed and has not been tested

<!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 is awesome! IE6/8 are all successful! Although IE7 has some problems, it basically doesn't affect it. By the way, please tell me, I used ieTester to test, is that okay?

I have never used IETESTER. After searching, Microsoft itself also provides one https://www.modern.ie/zh-cn, and there is also a BrowserStack that cooperates with it. There is a fee. , I think you can use these virtual browser software or services before the development is completed. In the end, it is most guaranteed to run on a real browser on a real machine
