我有一张桌子，我在其中存储项目ID及其说明。现在我将它们显示为来自mysql的下拉菜单。这是桌子
stock_id description
2013_1Mess_Jan Canteen
2013_Mess_August Canteen
2013_Mess_Dec Canteen
2013_Mess_July Canteen
2013_Mess_Nov Canteen
2013_Mess_Oct Canteen
2013_Mess_Sep Canteen
A4_Sheets Stationary
Aloo_Parantha Canteen
BBA11_4th_sem Fine
Biscuit_02 Canteen
Biscuit_05 Canteen
Biscuit_10 c Canteen
Black_White PrintOut
Book_Lost Library
BP_BBA12_2nd FIne
BP_PGDM_11 FIne
BP_PGDM_12 FIne
现在我要是如果我选择stock_id，那么说明将自动显示其说明。在这里库存是唯一的关键。这是我的代码（我知道使用ajax是可能的，但我对此是零）
<?php
$con = mysql_connect("localhost","root","");
$db = mysql_select_db("ex_smartcard2013",$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['stock_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>';
}
?>

您需要使用ajax发布URL ID并从ajax获取结果
var data = 'id='+yourid;
$.post(
'abc.php',
data
success(function(resp){
jsonData = $.parseJSON(resp);
alert(jsonData);
});
abc.php
id = $_POST['id'];
your query
echo json_encode(array(
description => $description
));
