现在我有一个下拉列表框，每次选择一个值以后就要刷新页面，然后所选的值就变为初始状态，有没有什么办法让刷新后所选的值不会改变。
代码如下：
<select id="id" name="nian" size="1" onChange="window.location.href='KHList.asp?id=<%=depid%>&nian='+(this.options[this.selectedIndex].value);">
<option value="" selected>请选择考核年份</option>
<option <%if nian=year(now()) then%>selected<%end if%> value="<%=year(now())%>"><%=year(now())%>年</option>
<option <%if nian=year(now())-1 then%>selected<%end if%> value="<%=year(now())-1%>"><%=year(now())-1%>年</option>
<option <%if nian=year(now())-2 then%>selected<%end if%> value="<%=year(now())-2%>"><%=year(now())-2%>年</option>
<option <%if nian=year(now())-3 then%>selected<%end if%> value="<%=year(now())-3%>"><%=year(now())-3%>年</option>
<option <%if nian=year(now())-4 then%>selected<%end if%> value="<%=year(now())-4%>"><%=year(now())-4%>年</option>
</select>

<%
nian=request("nian")
if not isnumeric(nian) or nian="" then nian=year(date)
nian = cint(nian)
%>
<select id="id" name="nian" size="1" onChange="window.location.href='KHList.asp?id=<%=depid%>&nian='+(this.options[this.selectedIndex].value);">
<option value="" selected>请选择考核年份</option>
<option <%if nian=year(now()) then%>selected<%end if%> value="<%=year(now())%>"><%=year(now())%>年</option>
<option <%if nian=year(now())-1 then%>selected<%end if%> value="<%=year(now())-1%>"><%=year(now())-1%>年</option>
<option <%if nian=year(now())-2 then%>selected<%end if%> value="<%=year(now())-2%>"><%=year(now())-2%>年</option>
<option <%if nian=year(now())-3 then%>selected<%end if%> value="<%=year(now())-3%>"><%=year(now())-3%>年</option>
<option <%if nian=year(now())-4 then%>selected<%end if%> value="<%=year(now())-4%>"><%=year(now())-4%>年</option>
</select>

$("select1").find("option[value=3]").attr("checked",true);

根据楼主的要求，可能cookie是比较好的解决方法，把每次选好的值放到cookie里，等页面刷新完了再重新读取cookie值，赋值给select

基本上就是三种保存上一页面数据的方式的选择，看那种更合适你现在的程序；
1.cookie
2.url
3.hidden表单
