Основной пример Select2 не работает

Я пытаюсь получить select2 библиотека, работающая со скриптом symfony2.

Я пытаюсь реализовать базовый пример предоставленной https://select2.github.io/examples.html страницы.

Таким образом я добавил в заголовок своей страницы:

<!-- SELECT 2-->
                            <link href="//cdnjs.cloudflare.com/ajax/libs/select2/4.0.0/css/select2.min.css" rel="stylesheet" />
                            <script src="//cdnjs.cloudflare.com/ajax/libs/select2/4.0.0/js/select2.min.js"></script>
                            <!-- /SELECT2 -->

и следуя этому коду, представленному в примере:

<script type="text/javascript">
     $(document).ready(function() {
$(".js-example-basic-single").select2();
});
</script>

<select id="appbundle_items_accountdebet" name="appbundle_items[accountdebet]" class="js-example-basic-single"><option value="1">001 - Środki trwałe x</option><option value="2">001-001 - Środek trwały 1 </option><option value="3">001-002 - Środek trwały 2 </option><option value="4">002 - Kasa</option><option value="7">04-33 - test</option><option value="10">05 - dff</option></select>

К сожалению, кажется, что я делаю что-то не так, потому что никаких визуальных изменений не происходит.

Решение

В вашем полном примере кода исправьте селектор класса, добавив "." перед именем класса измените:

 <SCRIPT type="text/javascript">
     $(document).ready(function() {
$("js-example-basic-single").select2();
});
</SCRIPT>

чтобы:

<script type="text/javascript">
     $(document).ready(function() {
$(".js-example-basic-single").select2();
});
</script>
  1. Вы включили JQuery на своей странице, прежде чем DOM готов код?

  2. предоставьте нам журнал консоли JS

  3. проверьте с помощью отладчика js, достигает ли парсер:

    $ ("JS-пример основного-сингл.") Select2().

кажется, ваш код работает нормально, по крайней мере, здесь: http://jsfiddle.net/8349tck1/

<link href="//cdnjs.cloudflare.com/ajax/libs/select2/4.0.0/css/select2.min.css" rel="stylesheet" />
<script src="//cdnjs.cloudflare.com/ajax/libs/select2/4.0.0/js/select2.min.js"></script>

<select id="appbundle_items_accountdebet" name="appbundle_items[accountdebet]" class="js-example-basic-single"><option value="1">001 - Środki trwałe x</option><option value="2">001-001 - Środek trwały 1 </option><option value="3">001-002 - Środek trwały 2 </option><option value="4">002 - Kasa</option><option value="7">04-33 - test</option><option value="10">05 - dff</option></select>
