javascript - BS Modal - 没有背景，没有覆盖并且能够在显示时聚焦输入字段？

问题描述

我使用没有背景和自定义叠加样式的 BS 模态，因此它们看起来像一个浮动窗口 - 例如用于 cookie 同意（但不仅限于此）。我知道要使button元素可点击，我必须设置

.modal { pointer-events: none }

但是，如果我想input在显示模态时使元素具有焦点（和可写），该怎么办？

如果您愿意，这是我的代码或小提琴。

$("#exampleModal").modal({
  backdrop: false,
  show: true
})
.modal { pointer-events: none; }
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.1.1/js/bootstrap.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.3/umd/popper.min.js"></script>
<script src="https://code.jquery.com/jquery-3.3.1.slim.min.js"></script>
<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.1/css/bootstrap.min.css" rel="stylesheet"/>

<!-- Button trigger modal -->
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal">
  Launch demo modal
</button>

<input type="text" value="Hi">

<!-- Modal -->
<div class="modal fade" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title" id="exampleModalLabel">Modal title</h5>
        <button type="button" class="close" data-dismiss="modal" aria-label="Close">
          <span aria-hidden="true">&times;</span>
        </button>
      </div>
      <div class="modal-body">
        ...
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Save changes</button>
      </div>
    </div>
  </div>
</div>

解决方案

您可以禁用引导程序设置shown的模态焦点侦听器。然后您也可以编辑文本字段。

$("#exampleModal").modal({
  backdrop: false,
  show: true
})

$('#exampleModal').on('shown.bs.modal', function() {
    $(document).off('focusin.modal');
});
.modal { pointer-events: none }
