js如何获得循环内下拉列表中的值

[Tmac柴]

<% Object Shopping = session.getAttribute("ShoppingCar");
if(Shopping != null)
{
Set<Goods> ShoppingCar = (Set<Goods>)Shopping;
Iterator<Goods> it = ShoppingCar.iterator();
while(it.hasNext())
{
Goods itnext = it.next();

%>
<tr>
<td><%=itnext.getName() %></td>
<td><%=itnext.getInstruction() %></td>
<td><%=itnext.getPrice() %></td>
<td>
<select name="<%=itnext.getId() %>" id="<%=itnext.getId()%>" size="1" onchange="return updatenumber('<%=itnext.getId()%>')">
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
<option value="5">5</option>
<option value="6">6</option>
<option value="7">7</option>
</select>
</td>
<td><a href="javascript:void(0)" onclick="return deleteById('<%=itnext.getId()%>');">删除</a></td>
</tr>
<%
}
}

%>

lz,你是要获取循环后的所有下拉框选中的值吗？

var sel=document.getElementById("sel"); alert(sel[sel.selectedIndex].value); ??不明白你的意思

直接用js里的menu多好
