私は2つの選択リストの次のコードを持っています.2番目のものは最初のものの選択に応じて情報を表示しています:
<head>
<script type="text/javascript" src="include-js/jquery-1.8.3.js"></script>
<script type="text/javascript" src="include-js/functions.js"></script>
</head>
<body>
<table border='1'>
<tr>
<td>
<select class="standing_countries" name="standing_countries">
<option class="country_element" id='1'>Ingiltere</option>
<option class="country_element" id='2'>Türkiye</option>
<option class="country_element" id='3'>Almanya</option>
<option class="country_element" id='4'>Ispanya</option>
<option class="country_element" id='5'>Italya</option>
<option class="country_element" id='6'>Fransa</option>
</select>

<td class='leagues' id='leagues'>

functions.js:
$(document).ready(function(){
$('.standing_countries').on('change',function(){
var select_id = $(this).children(":selected").attr("id");
if(select_id == 1)
{

2番目のリストオプションが選択されたときに警告するjQueryコードをいくつか書きましたが、最初のリスト(デフォルトリスト)でのみ機能しましたが、最初のリストからオプションを選択し、情報が2番目のリストに読み込まれると、選択しようとします2 番目のリストのオプションですが、アラートはトリガーされません。
誰でも私を助けることができますか?リストを使った jQuery は初めてですが、何が起こっているのですか?
