Question

我想在单击按钮时显示模态，但是模态不显示。

我将模式指定为按钮的数据目标，但我什么也没得到，控制台上也没有错误。

<button type="submit" data-toggle="modal" data- 
 target="#someModal">Test</button>
  <!-- Modal -->
 <div class="modal fade" id="someModal" role="dialog">
 <div class="modal-dialog">

  <div class="modal-content">
    <div class="modal-header">
      <button type="button" class="close" data-dismiss="modal">&times; 
    </button>
    </div>
    <div class="modal-body">
      <p>Modal text</p>
    </div>
    <div class="modal-footer">
      <button type="button" class="btn btn-default" data- 
      dismiss="modal">Close</button>
    </div>
  </div>

 </div>
 </div>

此代码在我的component.html页面中。

Answer 1

您在data-之后和target之前有一些空格。只需将它们放在同一行上即可。 data-dismiss的关闭按钮也是如此。另外，我将删除type="submit"，因为官方文档Modal - Bootstrap并不需要。

这是工作代码：

<button data-toggle="modal" data-target="#someModal">Test</button>
<!-- Modal -->
<div class="modal fade" id="someModal" role="dialog">
   <div class="modal-dialog">
     <div class="modal-content">
       <div class="modal-header">
         <button type="button" class="close" data-dismiss="modal">&times;</button>
       </div>
       <div class="modal-body">
         <p>Modal text</p>
       </div>
       <div class="modal-footer">
         <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
       </div>
     </div>
   </div>
</div>

我认为您尚未添加JQuery。因此，我通过添加bootstrap JQuery及其工作来获得代码。

<html>
  <head>
  <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" integrity="sha384-ggOyR0iXCbMQv3Xipma34MD+dH/1fQ784/j6cY/iJTQUOhcWr7x9JvoRxT2MZw1T" crossorigin="anonymous">

</head>
  <body>

  <button type="submit" data-toggle="modal" data-target="#someModal" class="btn btn-danger">Test</button>
  <!-- Modal -->
 <div class="modal fade" id="someModal" role="dialog">
 <div class="modal-dialog">

  <div class="modal-content">
    <div class="modal-header">
      <button type="button" class="close" data-dismiss="modal">&times; 
    </button>
    </div>
    <div class="modal-body">
      <p>Modal text</p>
    </div>
    <div class="modal-footer">
      <button type="button" class="btn btn-default" data- 
      dismiss="modal">Close</button>
    </div>
  </div>

 </div>
 </div>
 </body>
</html>
