示范效果的是用 JS 把 Select 中的 value 填入 Textbox 中.
要读出数据库中的数据到下拉框中只要用php生成 下面这段就OK了<?php
$Citys = mysql_fetch_array($res); //先取出城市
.
.
.$Sections = mysql_fetch_array($res); //然后取出区
?>
where[0]= new comefrom("请选择省份名","请选择城市名");
where[1] = new comefrom("<?php echo $city[0]; ?>","
<?php
foreach($section as $c)
{
echo "|".$c;
}
?>
");

这句话有问题，javascript和PHP之间不能传数组，只能传字符串，你需要转换一下！
