把frame的可见属性改为hidden就行了。yourframeid.style.visibility="hidden"

Answer 1

<frameset rows="100,*">
<frame src=about:top>
<frameset cols="100,*" id=frmMain>
<frame src='about:<input type=button value=x onclick=top.frmMain.cols="0,*">'>
<frame src=about:right>
</frameset>
</frameset>

Answer 2

用层了<div id="leftFrame" style="position:absolute; width:200px; height:300px; z-index:1; left: 100px; top: 120px; visibility: visible; background-color: #DDDDFF; border: 1px none #000000">
<table>
<tr>
<td width="95%">&nbsp;</td>
<td align="right">
<input type="button" name="clo" value="X" onClick="leftFrame.style.visibility='hidden'">
</td></tr>
</table>
</div>
