Ruby on rails 3 如何使用rails中的标记帮助器在选择标记上添加v-on:change属性

我试图在使用select_标记生成的select元素上添加v-on:change属性

像这样的

 <%= select_tag "worker_id", options_from_collection_for_select(@workers, "id", "name"), prompt: 'Choose', class: 'form-control', data: { "v-on:change" => "getWorker()" } %>

也试过

<%= select_tag "worker_id", options_from_collection_for_select(@workers, "id", "name"), prompt: 'Choose', {}, { class: 'form-control', "v-on:change" => "getWorker()" } %>

还是不走运。

试试：

<%= select_tag "worker_id", options_from_collection_for_select(@workers, "id", "name"), prompt: 'Choose', class: 'form-control', '@change': 'getWorker' %>

或：

正确的版本是使用@change和=>

<%= select_tag "worker_id", options_from_collection_for_select(@workers, "id", "name"), prompt: 'Choose', class: 'form-control', '@change' => 'getWorker' %>

是的，我的印象是，不管有没有，都没什么区别。不过，我还是对答案进行了编辑，使其更为恰当。

<%= select_tag "worker_id", options_from_collection_for_select(@workers, "id", "name"), prompt: 'Choose', class: 'form-control', '@change' => 'getWorker' %>
