想实现的 功能是：选择跟菜单1时显示listFunc里的内容。选择跟菜单2时显示listFunc1里的内容.

Answer 1

这个很好弄呀!在listview1的onchange事件里做判断,如果选择的是g1项则设置一下listFunc否则就设置listFunc1的状态......

Answer 2

function show()
{
    var view=document.getElementById("listview1");
    var frm=document.getElementById("listFunc");
    var frm1=document.getElementById("listFunc1")
    if(view.selectedIndex>=5)
      {
      frm.style.display="inline";
      frm1.style.display="none";
      }
    else
      {
      frm.style.display="none";
      frm1.style.display="inline";
      }    
}<select  name="listview1"  size="10" onchange="show();">  
                                                  <option  value="00">--可选择菜单-- </option>  
                                                  <option  value="g1">根菜单1 </option>  
                                                  <option  value="g1z1">-枝菜单1 </option>  
                                                  <option  value="g1z2">-枝菜单2 </option>  
                                                  <option  value="g1z2y1">--叶菜单1 </option>  
                                                  <option  value="g1z2y2">--叶菜单2 </option>  
                                                  <option  value="g2">根菜单2 </option>  
  </select>  
  //这里是fieldset

Answer 3

 还 是有点不 行啊！  
实现的功能是：选择跟菜单1时显示listFunc里的内容不显示listFunc1里的内容。选择跟菜单2时显示listFunc1里的内容不显示listFunc里的内容。
