JavaScript: Modal window

application.js

Implement and export as default the function that controls modal windows.

<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal">
  Launch demo modal
</button>
<div class="modal fade" id="exampleModal">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title" id="exampleModalLabel">Modal title 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">
        ...
      </div>
    </div>
  </div>
</div>

• Buttons of modal windows are found using the data-toggle="modal" selector
• The window's ID is stored in the button's data-target attribute
• To make the window pop up, you need to add the show class and set the display style to block in the element with a relevant id in a data-target
• The cross available by the selector data-dismiss="modal" hides the modal window. Clicking it has the opposite effect, the show class is removed, and display is set to none
