function pri_addOnchangeEvent()
{
var local_columns = pub_table_getColumns();
var len = tb.table.rows.length;
for (var row = 0; row < len; row++)
{
pub_table_setRowValue("0", tb.table.rows[row], FlagColumnName);
var province=pub_table_getRowCell(tb.table.rows[row],'province');
var city=pub_table_getRowCell(tb.table.rows[row],'city');
pub_object_addEvent(province.children[0], "onchange", change1);
pub_object_addEvent(city.children[0], "onchange", change1);
for (var col = 0; col < local_columns.length; col++)
{
var cell = pub_table_getRowCell(tb.table.rows[row], col);
if (cell.children.length > 0)
{
pub_object_addEvent(cell.children[0], "onchange", change);
}
}
}
}怎么写change1让province和city产生连动效果。最好把省份的名字和城市的名字也列出来，感激不尽！！

</script><select name="province" id="province"></select><select name="city" id="city">
</select>测试通过
<select name="province" id="province">
</select> <select name="city" id="city">
</select>
这些都不能写
只能pub_table_getRowCell来获得某一列的值
<script type="text/javascript">
var citys=[
["西安","咸阳","宝鸡","渭南","汉中"],
