Javascript 如何在Cascader Ant Design中显示子对象？

我在如何在console.log下面显示categorySubResponses和categorySubChildResponses中的数据时遇到问题

像这样的梦境来自虚拟数据

现在没有孩子了

我使用ant设计

https://ant.design/components/cascader/

我将代码放入

codesanbox.io

和链接中

https://codesandbox.io/embed/q-56619059-so-8dk0z

您需要

.map（）

categorySubResponses

和

categorySubResponses

为每个数组创建值和标签

const options = this.state.allCategory.map(category => ({
  value: category.id,
  label: category.name,
  children: category.categorySubResponses && category.categorySubResponses.map(child => ({
    value: child.id,
    label: child.name,
    children: child.categorySubChildResponses && child.categorySubChildResponses.map(innerChild => ({
      value: innerChild.id,
      label: innerChild.name
    })) || []
  })) || []
}));

代码清理

createSubChildren = (children = []) => {
  return (
    (children &&
      children.map(child => ({
        value: child.id,
        label: child.name
      }))) ||
    []
  );
};

createChildren = (children = []) => {
  return (
    children &&
    children.map(child => ({
      value: child.id,
      label: child.name,
      children: this.createSubChildren(child.categorySubChildResponses)
    }))
  ) || [];
};

const options = this.state.allCategory.map(category => ({
  value: category.id,
  label: category.name,
  children: this.createChildren(category.categorySubResponses)
}));
