Answer 1

<script language="JavaScript" type="text/javascript">
//ChangeSelect(上一级的值,下一级Select控件的ID值,下一级Select控件要选中的值(即value而非text),数据源数组名,默认显示字符(如:请选择...如果不写的话会用默认值填充))，第一级的上级值为0
function ChangeSelect(ParentValue, NextId, NextSelectedValue, ArrObj,DefaultStr)
{
StrObj = eval(document.getElementById(NextId));
StrObj.length = 0;
//判断它是二级数据源，还是三级
if (ArrObj.length > 0)
{
if (ArrObj[0].length == 2)
{ArrNum = 0;}
else
{ArrNum = 2;}
}
//显示所有列表
for (i = 0; i < ArrObj.length; i++)
{
if (i == 0)
{
if (DefaultStr == undefined ) DefaultStr="==请选择==";
StrObj.options[StrObj.length] = new Option(DefaultStr, "");
}
if (ArrObj[i][1] == ParentValue)
{
StrObj.options[StrObj.length] = new Option(ArrObj[i][0],ArrObj[i][ArrNum]);
}
}
//选中列表内某一项
for (i = 0; i < StrObj.length; i++)
{
if (StrObj.options[i].value == NextSelectedValue)
{
StrObj.options[i].selected = true;
}
}
//激发下一级的onchange事件以实现多级级联
StrObj.onchange();
}

获取不到你就传参数好了
var 要的值=document.getelementbyid("该属性id的名字").value
把这个要的值传过去不就好了
