我抓住列表框中的值並將它傳遞給另一個列表框,我已經使用一個值$ Lid工作,但現在我需要兩個$ Lid和$ Cid,這是正確的方式做這個?抓取兩個值Javascript
$(document).ready(function()
{
$(".Doggie").change(function()
{
var LocationString = $(this).find(":selected").val();
var CityString = $(this).find(":selected").val();
$.ajax({
type: "POST",
url: "ajax_city.php",
data: {Lid : LocationString, Cid : CityString},
cache: false,
success: function (html) {
$(".Kitty").html(html);
}
});
});
$('.Kitty').live("change",function(){
var LocationString = $(this).find(":selected").val();
var CityString = $(this).find(":selected").val();
$.ajax({
type: "POST",
url: "ajax_area.php",
data: {Lid : LocationString, Cid : CityString},
cache: false,
success: function (html) {
$(".Pig").html(html);
}
});
});
});
</script>
</head>
<body>
<div id="frame1">
<label>Place :</label>
<select name="Doggie" class="Doggie" id="Doggie">
<option selected="selected">--Select Place--</option>
<?php
$sql = mysql_query("SELECT tblLocations.RestID as Lid, tblLocations.CityID as Cid, tblRestaurants.RestName as name
FROM tblRestaurants INNER JOIN tblLocations ON tblRestaurants.RestID = tblLocations.RestID
GROUP BY tblLocations.RestID, tblRestaurants.RestName
ORDER BY tblRestaurants.RestName ASC");
while($row=mysql_fetch_array($sql))
{
echo '<option value="'.$row['Lid'].''.$row['Cid'].'">'.$row['name'].'</option>';
} ?>
</select>
<label>City :</label>
<select name="Kitty" class="Kitty" id="Kitty">
<option selected="selected">--Select City--</option>
</select>
<label>Area: :</label>
<select name="Pig" class="Pig" id="Pig">
<option selected="selected">--Select Area--</option>
</select>
</div>
</body>
</html>
而且......
<?php
require ('config.php');
if ($_POST['Lid']) {
$Lid = $_POST['Lid'];
$sql = mysql_query("SELECT tblLocations.RestId as Lid, tblLocations.CityID as Cid, tblCities.CityName as name
FROM tblLocations INNER JOIN tblCities ON tblLocations.CityID = tblCities.CityID
WHERE tblLocations.RestID = $Lid
GROUP BY tblLocations.RestID, tblCities.CityName
ORDER BY tblCities.CityName ASC");
echo '<option selected="selected">--Select City--</option>';
while ($row = mysql_fetch_array($sql)) {
echo '<option value="' . $row['Lid'] . '' . $row['Cid'] . '">' . $row['name'] . '</option>';
}
}
?>
眼下它不返回任何東西,所以我必須承擔其錯誤。謝謝。
然而,我做了改變;仍然沒有收到任何數據。這部分是否正確的第二個代碼片段?如果($ _POST ['Lid']){ $ Lid = $ _POST ['Lid']; –
@ ME-dia您需要像我在我的回答中那樣更改LocationString和CityString的值。 – marteljn
@ ME-dia你做了一些不必要的事情,看看更新。你的php看起來不錯。 –
