select下拉框遮住div层的解决方法(用iframe解决)

在层里放一个比select级别高的iframe就可以了

 

<div id=”menu” style=”position:absolute; visibility:hidden; top:20px; left:20px; width:100px; height:200px; background-color:#6699cc;”>
  <table>
  <tr><td>item 1</td></tr>
  <tr><td>item 2</td></tr>
  <tr><td>item 3</td></tr>
  <tr><td>item 4</td></tr>
  <tr><td>item 5</td></tr>
  </table>
  <iframe src=”javascript:false” style=”position:absolute; visibility:inherit; top:0px; left:0px; width:100px; height:200px; z-index:-1; filter=’progid:DXImageTransform.Microsoft.Alpha(style=0,opacity=0)’;”></iframe>
</div>



<a href=”#” onclick=”document.getElementById(’menu’).style.visibility=’visible’”>menu</a>
<form>
  <select><option>A form selection list</option></select>
</form>
