Question

所以我有这个

{% for producto in reparto_martes %}
       <div class="col-md-3">
        <div class="card mb-4 box-shadow product-box">
          <img class="card-img-top product-photo" data-src="holder.js/100px225?theme=thumb&amp;bg=55595c&amp;fg=eceeef&amp;text=Thumbnail" alt="Thumbnail [100%x225]" style="height: 225px; width: 100%; display: block;" src={{ producto.foto }} data-holder-rendered="true">
          <div class="card-body">
            <h4 class="card-text producto_precio">${{ producto.precio }}</h4>
            <h5 class="card-text producto_nombre">{{ producto.nombre }}</h5>
            <div class="d-flex justify-content-between align-items-center">
              <button type="button" class="btn btn-success anadir_button">Añadir</button>
              <small class="text-muted"></small>
            </div>
          </div>
        </div>
      </div>
{% endfor %}

它看起来像这样：https://gyazo.com/0b329d87af9372250a53ae25347b59b0

当用户单击anadir_button时，我需要选择项目名称。

$(document).ready(function(){
    $(".anadir_button").click(function(){
        $('.producto_precio').clone().appendTo('#list_pedidos');
    });
});

^这只是选择了所有三个项目（香蕉，bolson frutal，almendras）

$('.producto_precio').last()clone().appendTo('#list_pedidos');

^而这个只是选择'almendras'。

您需要从当前单击的按钮开始，然后导航到最近的 .card-body 祖先。现在您可以找到相应的产品。

这里是一个例子：

$(".anadir_button").click(function(e){
  console.log($(this).closest('.card-body').find('.producto_nombre').text());
                   //^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
});
