javascript - 每次点击后的确认模式。第一次有效，然后失败。 (模态上的模态)

Question

我正在使用 Bootstrap 启动选择模式，然后启动表单模式，最后在用户单击发送后启动确认模式。

这第一次工作正常，但是之后，确认模式不会弹出，它只是简单地退出。

这是我的代码:

HTML:

<button type="button" class="btn" data-toggle="modal" data-target="#chooseModal">Open</button>

<!-- Select One Modal -->
<div class="modal fade" id="chooseModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
  <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>
        <h2 class="modal-title" id="myModalLabel">Select An Option</h2>
      </div>
      <div class="modal-body">
        <button type="button" class="btn" data-toggle="modal" data-target="#myForm">Click to Email</button>
        <button type="button" class="btn" data-toggle="modal" data-target="#chooseModal">Click to Do Something Else</button>
      </div>
    </div>
  </div>
</div> 

<!-- Email Form Modal-->
<div class="modal fade" id="myForm" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
  <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>
        <h4 class="modal-title" id="myModalLabel">Email</h4>
      </div>
      <div class="modal-body">

        <div class="row">
            <div class="col-xs-12" id="emailInput">
                <h4>To:</h4>
                <input type="text" name="email" id="email"> 
            </div>
            <div class="col-xs-12">
                <h4>Subject:</h4>
                <input type="text" value="subject" name="emailSubject" id="emailSubject"> 
            </div>
            <div class="col-xs-12">
                <h4>Body:</h4>
                <textarea rows="4" id="emailBody"></textarea>
            </div>
            <div class="col-xs-1">
                <button onclick="confirmAlert()" type="button" class="btn" data-toggle="modal" data-target="#myForm">Send</button>
            </div>
        </div>

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


<!-- Confirmation Modal -->
<div class="modal fade" id="PDFconfirmation" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
  <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>
        <h2 class="modal-title" id="myModalLabel">Thank You!</h2>
      </div>
      <div class="modal-body">
        <h2>Your message has been sent.</h2>
      </div>
    </div>
  </div>
</div>  

Javascript:

function confirmAlert(){ 

    $(".modal, .modal-backdrop").hide();

    $('#PDFconfirmation').modal('show');

    setTimeout(function(){
        $("#PDFconfirmation, .modal, .modal-backdrop").hide();
    }, 2000);

}

Answer 1

您应该将 JS 代码更改为:

function confirmAlert(){ 

  $("#chooseModal").modal('hide');

  $('#PDFconfirmation').modal('show');

  setTimeout(function(){
    $("#PDFconfirmation").modal('hide');
  }, 2000);

}

但是，您可以改进此代码，但现在您可以更好地了解应该如何切换(显示/隐藏)模态以防止此类错误。
