<div class="listmenuclass" style=" top:60px" onclick="JavaScript:naviToUrl('onlyforzhou','UBSC/OtherForChangAn/StrategyReport/BPO_REP_DayAnalysis.aspx','周分析','周分析')">

</div>
.listmenuclass
{
height:60px;
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 )
