我想在我的Symfony表单中启用select 2搜索到目前为止我尝试过:
在我的表单类中,我有这个:
->add('parent', EntityType::class, [
'class' => Category::class,
'choice_label' => 'title',
'attr' => [
'class' => 'select2'
]
])
在我的twig文件中:
<head>
<link href="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.2-rc.1/css/select2.min.css" rel="stylesheet" />
<!-- Loading jquery here--><script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.0/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.2-rc.1/js/select2.min.js"></script>
</head>
{{ form_start(form) }}
<script type="text/javascript">
$('select').select2();
</script>
{{ form_widget(form) }}
{{ form_end(form) }}
但是我没有得到搜索栏的下拉菜单.只是Symfony的默认下拉菜单.我究竟做错了什么
