给楼主一个例子作参考
 程序代码：<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www."> <html xmlns="http://www."> <head> <meta http-equiv="Content-Type" content="text/html; charset=gb2312" /> <title>div弹出层</title> <style type="text/css"> * { margin:0; padding:0;} #x1 {width:100px; height:100px; background-color:Orange;} #x2 {width:100px; height:100px; position:absolute; top : 100px; left:0px; background-color:Red;z-index:99} #x3 { width:100px; height:100px; background-color:Blue; } </style> <script> function cha() { document.getElementById("x2").style.display=""; } function cha1() { document.getElementById("x2").style.display="none"; } </script> </head> <body> <div id="x1" onmouseover="javascript:cha();" onmouseout="javascript:cha1();"> 第一层 </div> <div id="x2" style="display:none">第二层</div> <div id="x3">第三层</div> </body> </html> |
