根据其他页面中的其他选定值，在模式选择框中选择一个选项

Question

我手风琴在这里是代码：

<div class="accordion">
            <div class="accordion-title accordion-area">
              <a href="#joinus/jr-software-engineer/" id="accordion-link">Junior Software Engineer</a>
            </div>
            <div class="accordion-container">This is the Body <a href="#apply" class="btn btn-hire"> Apply Now</a></div>
            <div class="accordion-title accordion-area">
              <a href="#joinus/sr-software-engineer/" id="accordion-link">Senior Software Engineer</a>
            </div>
            <div class="accordion-container">This is the Body <a href="#apply" class="btn btn-hire"> Apply Now</a></div>
            <div class="accordion-title accordion-area">
              <a href="#joinus/software-engineer-intern/" id="accordion-link">Intern Software Engineer</a>
            </div>
            <div class="accordion-container">This is the Body <a href="#apply" class="btn btn-hire"> Apply Now</a></div>
</div>

单击每个单独的“应用”按钮后，此模式将打开：

<div id="apply" class="modal-holder">
  <a class="base-close" href="#joinus"></a>
  <div class="modal">
    <a class="close-modal" href="#joinus"><i class="fa fa-times"></i></a>
    <div class="modal-header">
      Apply
    </div>
    <div class="modal-body">
      <%= form_for @job_application do |f| %>
        <div class="row" role="list">
          <div class="col-6">
            <div class="form-holder">
              <%= label_tag(:role, 'Job Position *') %>
              <%= f.select :role, options_for_select(['Junior Software Engineer','Senior Software Engineer', 'Intern Software Engineer']), class: 'text-box' %>
            </div>
          </div>  
        </div>
        <%= submit_tag 'Send', class: 'btn btn-primary btn-large' %>
      <% end %>
    </div>
  </div>
</div>

现在发生的事情是选择框中的作业列表与代码中的位置相同，但是我希望每当从单击了该模式的作业链接中打开一个模式时，都将在以下位置预先选择职位这样的“选择”框将出现在列表的第一位，并且默认情况下处于选中状态。我想使用jQuery和Ruby on Rails的简单表单来实现它。

您可以为标签添加类，然后使用javascript进行预选择
