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]--> ...
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?
