被遮盖的div 下面的代码
<!--列表菜单-->
<div id="opreationmenu" style="position: absolute; left: 0px; top: 0px; width: 200px;
height: 240px; background: #ffffff; display: none;">
<iframe frameborder='1' style='-moz-opacity: 0; -webkit-opacity: 0; opacity: 0; position: absolute;
visibility: inherit; top: 0px; left: 0px; height: 240px; width: 200px; z-index: 10;
background: none'></iframe>
<div class="listmenuclass" style=" top:0px" onclick="JavaScript:naviToUrl('onlyforri','UBSC/BusiPLAN/ReportModel/BPO_REP_DayReport.aspx','日分析','日分析')">
日</div>
<div class="listmenuclass" style=" top:60px" onclick="JavaScript:naviToUrl('onlyforzhou','UBSC/OtherForChangAn/StrategyReport/BPO_REP_DayAnalysis.aspx','周分析','周分析')">
周</div>
<div class="listmenuclass" style=" top:120px" onclick="JavaScript:naviToUrl('onlyforyue','UBSC/OtherForChangAn/StrategyReport/BPO_REP_KPIORG.aspx','月分析','月分析')">
月</div>
<div class="listmenuclass" style=" top:180px" onclick="JavaScript:naviToUrl('onlyforji','UBSC/Strategy/BPO_StrategyMonitoring.aspx?StrategyLevel=0','季分析','季分析')">
季</div>
</div>
.listmenuclass
{
height:60px;
width:200px;
border:solid 1px;
font-size:18px !important;
text-align:center;
line-height:60px;
border-top:none;
cursor:pointer;
position:absolute;
z-index:999999999;
}
1.解决方法在div同层上加一个iframe 并设置 绝对位置 和z-index 的大小
2.在div上 设置绝对位置 和z-index （大于iframe 的z-index ）
