嗨，我有一张发票页面，我可以使用jquery添加行。我能够从.js文件添加纯文本框，但我想添加一个文本框的下拉菜单。就像php页面中的默认行一样。
我的网页代码是
<?php
$con = mysql_connect("localhost","root","");
$db = mysql_select_db("inventory_erp",$con);
$getitem=mysql_query("SELECT * FROM 0_stock_master ORDER BY stock_id ASC");
$item = '';
while($row = mysql_fetch_assoc($getitem))
{
$item .= '<option value = "'.$row['id'].'">'.$row['stock_id'].'</option>';
}
$getdescription=mysql_query("SELECT * FROM 0_stock_master ");
$description = '';
while($row2 = mysql_fetch_assoc($getdescription))
{
$description .= '<option value = "'.$row2['description'].'">'.$row2['description'].'</option>';
}
?>

我在exampe.js文件中使用此代码在新行中添加文本框（描述）。但我想从mysql数据库下载菜单。
