大家帮我看看我这个页面的div里面的display:none无效

document.getElementById("menu1").style.display="";
这句应该改成
document.getElementById("menu1").style.display="block";试试

    把div改成span<%@ page contentType="text/html;charset=gb2312"%>
    <%@ page import="java.util.*,otherbean.MountGuardBean;"%>
    <html>
    <head>
    <title>查询结果</title>
    <link href="js/style_IE.css" rel="stylesheet" type="text/css">
    </head>
    <%Iterator it = (Iterator) request.getAttribute("myit");%><body onload="">

     document.getElementById("menu1").focus();
    }
    function hideMenu(){
     document.getElementById("menu1").style.display="none";
    }
