急，二级连动怎样让所选择的经过连动查询后还处于被选状态。分不够可再加。

没人理我？

[nothingall]

谁来帮我？

[chjpeng]

...就是下面这段代码。。。

if (citys[i][2]==citysvalue)
{
document.all.area2.options[document.all.City.length] = new Option(citys[i][1], citys[i][2],false,true);
}
else
{
document.all.area2.options[document.all.City.length] = new Option(citys[i][1], citys[i][2],false,false);
}

[chjpeng]

应该是：
if (citys[i][2]==citysvalue)
{
document.all.City.options[document.all.City.length] = new Option(citys[i][1], citys[i][2],false,true);
}
else
{
document.all.City.options[document.all.City.length] = new Option(citys[i][1], citys[i][2],false,false);
}

选择后写入COOKIE。

[nothingall]

选择后我用了两个变量接过来值，省份的简单在Option做个判断即可
<%if rs1("locationid")=cint(biglocation_c) then%>selected<%end if%>
而城市的是且javascript的数组我应在哪里做判断输出selected?应怎样改写?

~~~~~~~~~
写入COOKIE，这个我更昏。本人实在有点菜，希望大家帮助一下。。谢谢。。
