在此屏幕上，我需要将购物篮中的产品数量添加到我的购物篮图标中： https://ibb.co/PcvM9Dr

我该怎么做？

请帮助我

Answer 1

您可以使用此代码

其他CSS：

<li class="nav-item position-relative">
    <a class="nav-link" href="#"><img src="img/basket.jpg" class="pl-lg-4 pr-2">
    <span class="badge badge-primary count">5</span >
    <span class="ml-2 d-lg-none d-xl-inline">Koszyk</span></a>
</li>

最后是HTML：

const selectFood = (event, food) => {
    let newSelected = [food.name];
    setSelected(newSelected);
  };

不要忘记在 li.nav-item

中添加类 .position-relative
