简单的js给页面添加遮罩层
<html>
<head><title>新文件标题</title><script type="text/javascript"> function Ceng() { document.getElementById('ceng').style.display = 'block'; document.getElementById('close').style.display = 'block'; return false; } function closeCeng() { document.getElementById('ceng').style.display = 'none'; document.getElementById('close').style.display = 'none'; return false; } </script></head><body><a href="#" onclick="Ceng()">点击弹出</a><div id="ceng" style="position:absolute;z-index:2;left:0;top:0;right:0;filter:alpha(opacity=50);margin:1px 1px;display:none;width:100%;height:100%;text-align:center;"> </div><div id="close" style="position:absolute !important;left:30%;top:0px;z-index:3;border:1px solid #ff6600;margin:100px auto;padding:0px;display:none;width:400px;height:300px;text-align:right"><a href="#" onclick="closeCeng()">关闭</a><div style="text-align:center;"><br><br> <a href="#">点击查看 >></a></div></div></body></html> 该文转摘出处不详0.0
****************************有时候遮罩层显示不出来,莫捉急,请看下面***********************************
当你的页面中有position:absolute时,咱们的写的position:absolute可能会失效
<div id="ceng" style="position:absolute;z-index:2;left:0;top:0;right:0;filter:alpha(opacity=50);margin:1px 1px;display:none;width:100%;height:100%;text-align:center;">将position:absolute;换成position: fixed;_position: absolute;可能换出现奇迹!!!
ps:第一次写,菜鸟刚入手,如有错误请pass
