隐藏的弹出事件不能在bootstrap模式上工作

Question

我试图在bootstrap关闭时触发回调函数。但它没有用。我用过的代码：

<div class="modal" id="overlayyy" role="dialog" aria-labelledby="exampleModalCenterTitle" aria-hidden="true">
  <div class="custom-modal modal-dialog modal-dialog-centered" role="document">
    <div class="container">
      <div class="modal-content">
        <div class="modal-body text-center">
          <iframe class="custom-iframe" id="myModalll" src="<?php echo $link; ?>"></iframe>
        </div>
      </div>
    </div>
  </div>
</div>

JS使用：

$('#overlayyy').on('hidden.bs.modal', function ()
{
    alert('hide event fired!');
});

Answer 1

请务必查看以下几点：

1）你是否以正确的方式包括了图书馆：Bootstrap Starter Guide

2）删除模态中的container类，以防万一。

3）检查你的custom-modal类与Bootstrap Modal没有冲突。

您可以使用代码作为基础检查下一个工作示例。

$('#overlayyy').on('hidden.bs.modal', function()
{
    alert('hide event fired!');
});

<!-- Button to trigger modal -->
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#overlayyy">
  Open Modal
</button>

<!-- Modal -->
<div class="modal" id="overlayyy" tabindex="-1" role="dialog" aria-labelledby="exampleModalCenterTitle" aria-hidden="true">
