javascript - Bootstrap 模式 : only when using the fade class 中的滚动问题

我花了好几个小时调试这个问题。这是我正在做的:

我打开一个 Bootstrap 模式
在该模态中，我打开另一个模态(我使用 data-dismiss 属性确保先关闭现有模态)
如果第二个模态非常大并且需要滚动，那么这将失败。不是滚动模式，而是滚动背景。

用于从现有模态中打开新模态的代码:

<button type="button" class="btn btn-secondary" data-toggle="modal" data-dismiss="modal" data-target="#modal2">Open modal 2</button>

我发现当我将“模态淡入淡出”类应用于模态时会出现问题。如果我删除“淡入淡出”类，那么它一切正常!但我真的很想使用淡入淡出类。这应该是这样的吗？或者有解决方法吗？下面是一个完整的工作示例:

.modal-body {
      height: 1000px
    }

<body>

  <button data-toggle="modal" data-target="#modal1">Open modal</button>

  <div class="modal fade" tabindex="-1" role="dialog" id="modal1">
    <div class="modal-dialog" role="document">
      <div class="modal-content">
        <div class="modal-header">

          <button type="button" class="close" data-dismiss="modal" aria-label="Close">
                <span aria-hidden="true">&times;</span>
              </button>
        </div>
        <div class="modal-body">
          <p>Modal body text goes here.</p>
        </div>
        <div class="modal-footer">
          <button type="button" class="btn btn-secondary" data-toggle="modal" data-dismiss="modal" data-target="#modal2">Open modal 2</button>

        </div>
      </div>
    </div>
  </div>

</body>

</html>

最佳答案

.modal-body {
      height: 1000px
    }
    #modal2{
      overflow-y:auto;
    }

<button data-toggle="modal" data-target="#modal1">Open modal</button>

  <div class="modal fade" tabindex="-1" role="dialog" id="modal1">
    <div class="modal-dialog" role="document">
      <div class="modal-content">
        <div class="modal-header">
          <h5 class="modal-title">Modal 1</h5>
          <button type="button" class="close" data-dismiss="modal" aria-label="Close">
                <span aria-hidden="true">&times;</span>
              </button>
        </div>
        <div class="modal-body">
          <p>Modal body text goes here.</p>
        </div>
        <div class="modal-footer">
          <button type="button" class="btn btn-secondary" data-toggle="modal" data-dismiss="modal" data-target="#modal2">Open modal 2</button>
        </div>
      </div>
    </div>
  </div>
  <div class="modal fade" tabindex="-1" role="dialog" id="modal2">
    <div class="modal-dialog" role="document">
      <div class="modal-content">
        <div class="modal-header">
          <h5 class="modal-title">Modal 2</h5>
          <button type="button" class="close" data-dismiss="modal" aria-label="Close">
                <span aria-hidden="true">&times;</span>
              </button>
        </div>
        <div class="modal-body">
          <p>Modal body text goes here.</p>
        </div>
        <div class="modal-footer">
          <button type="button" class="btn btn-secondary" data-toggle="modal" data-dismiss="modal" data-target="#modal1">Open modal 1</button>
        </div>
      </div>
    </div>
  </div>

如果你在这里谈论解决方法，那么你可以做这样的事情

#modal2{
  overflow-y:auto;
}

这是工作 JSFiddle
