efs框架表现层获取页面传送值

前一个页面中
<IMG SRC="images/tunel/main.gif" WIDTH="1143" HEIGHT="529" BORDER="0" ALT="">
 <div style="z-index:100; position:absolute; left:23px; top:490px; cursor: hand;" id="1#">
     <table border="0" width="86" >
                <tr>
                    <td height="21" nowrap align="right" background="images/tunel/a_1.gif" ext:qtip="1#断面" id="duanmian1" OnClick="window.open('viewdetail.aspx?method=duanmian1','newwindow','height=800,width=800,top=0,left=0,toolbar=no,menubar=no,scrollbars=no, resizable=no,location=no, status=no')">&nbsp;</td>
                </tr>
     </table>然后在'viewdetail.aspx页面中如何取得上面'viewdetail.aspx?method=duanmian1'method的值？并关联viewdetail.aspx页面中的treepanel中duanmian1的node选中打开？注：我是用efs框架的表现层
