javascript - Bootstrap 4 输入外部值

问题描述

我正在尝试使用 bootstrap 4 构建一个表单，但就我而言，我从未成功在输入文本客户端中为模态表单设置值，它永远不会工作......

表格是：

$('#contact-modal').on('show.bs.modal', function() {
    alert("prima");
    $("#name").attr({
      "value": 'ëtestí'
    });
  })
<script src="https://code.jquery.com/jquery-3.3.1.slim.min.js" integrity="sha384-q8i/X+965DzO0rT7abK41JStQIAqVgRVzpbzo5smXKp4YfRvH+8abtTE1Pi6jizo" crossorigin="anonymous"></script>

<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#contact-modal">
  modal
</button>

<div id="contact-modal" class="modal fade" role="dialog">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <a class="close" data-dismiss="modal">◊&lt;/a>
        <h3>Contact Form</h3>
      </div>
      <form id="contactForm" name="contact" role="form">
        <div class="modal-body">
          <div class="form-group">
            <label for="name">Name</label>
            <input type="text" name="name" class="form-control">
          </div>
          <div class="form-group">
            <label for="email">Email</label>
            <input type="email" name="email" class="form-control">
          </div>
          <div class="form-group">
            <label for="message">Message</label>
            <textarea name="message" class="form-control"></textarea>
          </div>
        </div>
        <div class="modal-footer">
          <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
          <input type="submit" class="btn btn-success" id="submit">
        </div>
      </form>
    </div>
  </div>
</div>

永远不起作用的功能是：

  $('#contact-modal').on('show.bs.modal', function() {
    alert("prima");
    $("#name").attr({
      "value": ëtestí
    });
  })

我真的可以使用任何帮助，谢谢！
