请问那位现成的javascript工具条，最好解决了div透明

就是，用javascript实现的：如，
<div id="block1" onmouseout="drag=0" onmouseover="dragObj=block1; drag=1;" style="position:absolute; left:115px; top:555px; width:650px; height:23px; z-index:1; overflow: visible; visibility: visible;cursor: move;"> 
　
    <table width="100%" border="1" cellspacing="0" cellpadding="0" bgcolor=#fofofo style="BORDER-COLLAPSE: collapse" borderColor=#a8a8a8>
      <tr>
        <td class="EXPLAIN" valign=middle> 
          <div align="center">
            <span onclick="rdl_change('0')" style="cursor: hand;" title="旋转该图片并复位">0度</span> 
            <span onclick="rdl_change('1')" style="cursor: hand;" title="将该图片旋转90度">90度</span> 
            <span onclick="rdl_change('2')" style="cursor: hand;" title="将该图片旋转180度">180度</span> 
            <span onclick="rdl_change('3')" style="cursor: hand;" title="将该图片旋转270度">270度</span>&nbsp;︱ 
           </div></td>     
    </table>
 　
</div>
