javascript - Bootstrap 4 输入分机值

Question

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

形式是:

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

<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">◊</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>

永远不起作用的函数是:

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

我真的需要任何帮助，谢谢!

您应该按名称定位输入:

<script>
    $('#contact-modal').on('show.bs.modal', function() {
        alert("prima");
        $("input[name='name']").val("ëtestí");
    })
</script>
