object不能被透明覆盖

Question

我现在能够把object通过div+iframe来覆盖上,但却不能实现完全透明覆盖.倘若完全透明,就会使得div+iframe不能覆盖在object之上.因此,在此寻求各位指点.
<div class="article_bj" style="top: 5px; z-index: 0">
            <object id="XXXX" codebase="XXXX.cab#Version=1,0,0,1" classid="clsid:7807DFC6-A228-402E-952C-DDFDF709FB22">
                <param name="wmode" value="Transparent" />
                <param name="_Version" value="65536">
                <param name="_ExtentX" value="9155">
                <param name="_ExtentY" value="6800">
                <param name="_StockProps" value="0">
            </object>
        </div>
        <div style="z-index: 2; position: absolute; top: 248px; left: 180px; background: url(../../Images2q/icok2.gif);
            display: block; width: 60%; height: 60px; filter: alpha(opacity=0);" name="DivStatus" id="DivStatus">
        </div>
        <iframe style="z-index: 1; position: absolute; top: 248px; left: 180px; width: 60%;
            height: 60px; filter: alpha(opacity=99);" src="EmptyJK.aspx"
            name="ifmStatus" id="ifmStatus" frameborder="0"></iframe>
