模式显示onclick jQuery

Question

我想在按钮单击时显示模式。我遵循了引导程序文档，但是由于某种原因，该模式没有弹出。这是我的代码：

模式：

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

                </button>
            </div>
            <div class="modal-body">
                <p>.............</p>
            </div>
            <div class="modal-footer">
                ..........
            </div>
        </div>
    </div>
</div>

按钮：

 <button type="button" class="btn btn-secondary btn-view-details"
data-toggle="modal"> View Details</button>

Jquery：

  $(document).ready(function(){
            $('button.btn-view-details').on('click', function () {
                $('#commonModal').modal('show');
            })
 })

Answer 1

在按钮上，您可以添加data-target属性，不需要通过jQuery触发弹出窗口：

<button type="button" class="btn btn-secondary btn-view-details"
data-toggle="modal" data-target="#commonModal"> View Details</button>

Answer 2

您只需添加bootstrap CDNs

$(document).ready(function() {
  $('button.btn-view-details').on('click', function() {
    $('#commonModal').modal('show');
  })
})

        </button>
      </div>
      <div class="modal-body">
        <p>.............</p>
      </div>
      <div class="modal-footer">
        ..........
      </div>

Button:

<button type="button" class="btn btn-secondary btn-view-details" data-toggle="modal"> View Details</button>
