Question

我正在尝试使用Bootstrap 4 Modal代码修复我的代码中的奇怪错误。我只是从这里复制并粘贴了代码：https://getbootstrap.com/docs/4.0/components/modal/#events

这是针对汽车网站的，Im尝试根据要求通过data属性传递库存和VIN。问题是这如何与foreach循环一起使用。它可以在单个Wordpress页面或Post上运行，但不会从循环的每个部分提取数据。

<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal" data-stock="<?php echo $vehicle['stock_number'];?>">Check Availability</button>

    <div class="modal-dialog" role="document">
        <div class="modal-content">
            <div class="modal-header">
                <h5 class="modal-title" id="exampleModalLabel">Stock</h5>
                <button type="button" class="close" data-dismiss="modal" aria-label="Close">
                    <span aria-hidden="true">&times;</span>
                </button>
            </div>

            <div class="modal-body">
                <form>
                    <div class="form-group">
                        <label for="recipient-name" class="col-form-label">Recipient:</label>
                        <input type="text" class="form-control" id="recipient-name">
                    </div>
                    <div class="form-group">
                        <label for="message-text" class="col-form-label">Message:</label>
                        <textarea class="form-control" id="message-text"></textarea>
                    </div>
                </form>
            </div>

            <div class="modal-footer">
                <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
                <button type="button" class="btn btn-primary">Send message</button>
            </div>
        </div>
    </div>
</div>

还有我的Jquery代码（函数（$）{

$('#exampleModal').on('modal.fade.show', function (event) {
    alert( "clicked" );
  var button = $(event.relatedTarget) // Button that triggered the modal
  var recipient = button.data('stock') // Extract info from data-* attributes
  // If necessary, you could initiate an AJAX request here (and then do the updating in a callback).
  // Update the modal's content. We'll use $ here, but you could use a data binding library or other methods instead.
  var modal = $(this)
  modal.find('.modal-title').text('New message to ' + recipient)
  modal.find('.modal-body input').val(recipient)
})})( jQuery );```

从功能上来说，这是可行的，只是不在foreach循环中生成的动态页面内。这些按钮已应用了适当的数据属性，但数据似乎没有从循环传递到模式。我有一个开发页面，您可以在此处进行实时查看，有问题的按钮是“检查可用性” http://windsor.sixomedia.ca/inventory/New/

尝试一下

var recipient = button.data('data-stock');

希望有帮助。
