在 bootstrap 弹出框插件中插入一个关闭按钮

Question

我想在右上角的bootstrap popover插件中插入一个关闭按钮，如图所示，我尝试了很多其他人在互联网上提出的方法，但它不起作用，也许我做错了..

Something like the red close button on the top right corner

<nav class="navbar">
    <div class="container navbar-cart">
        <ul class="navbar-nav ml-auto">
            <li>
               <a id="cart-popover" class="btn" data-placement="left" title="Shopping Cart">
                 <i class="fa fa-shopping-cart"></i>
                 <span class="badge"></span>
                 <span class="total_price">RM 0.00</span>
               </a>
            </li>
        </ul>
    </div>
</nav>

<div id="popover_content_wrapper" style="display: none">
   <button type="button" class="close">&times;</button>
    <span id="cart_details"></span>
    <div align="right">
        <a href="#" class="btn btn-primary" id="check_out_cart">
          <i class="fa fa-shopping-cart"></i> Check Out
        </a>
        <a href="#" class="btn btn-danger" id="clear_cart">
          <i class="fa fa-trash"></i> Clear
        </a>
    </div>
</div>

//show cart
     $('#cart-popover').popover({
       html : true,
       content:function(){
          return $('#popover_content_wrapper').html();
       }
    });

$('.close').on('click', function (event) {
        $('#popover_content_wrapper').hide();
    });

这是您的预期输出：

在此处阅读更多内容：http://getbootstrap.com/docs/4.1/components/popovers/#options

$(document).ready(function(){
     $('#cart-popover').popover({
       html : true,
       title:function(){
          return $('.popover_title').html();
       },
       content:function(){
          return $('#popover_content_wrapper').html();
       }
       
    });
      
});    

$(document).on('click','.close-popover',function(){
  $('#cart-popover').popover('hide');
});
