Answer 1

默认情况下隐藏输入时，

autofocus无法正常工作。你必须在JS中这样做：

$('#myModal').on('shown.bs.modal', function() {
    $(this).find('textarea[name="YYY"]').focus();
});

Answer 2

使用Textarea中的自动对焦检查示例

Answer 3

隐藏输入后，

自动对焦功能不起作用。使用显示的事件进行焦点$('#myModal').on('shown', function() { })

＆＃13;

$(document).ready(function(){
 $('#myModal').modal('show');
    $('#myModal').on('shown', function() {
        $("#remark").focus();
    })
 
})

＆＃13;

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.2.0/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/>

<!-- Modal -->
<div id="myModal" class="modal fade" role="dialog">
  <div class="modal-dialog">

    <!-- Modal content-->
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal">&times;</button>
        <h4 class="modal-title">Modal Header</h4>
      </div>
      <div class="modal-body">
        <p>Some text in the modal.</p>
        <textarea id="remark" autofocus></textarea>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
      </div>
    </div>

  </div>
</div>
