在 onClick 事件中取数组 Index 值

Question

如何在我的 React 应用程序中编写一个 onClick 事件以获取此代码中的数组索引？我只想获取数组索引作为输出

这是我在 JSON 文件中的数组。

{
        "Women": [
            {
                "id"  : 1,
                "name"  : "See All",
                "children" : [""]
            },
            {
                "id"  : 2,
                "name"  : "Clothes",
                "children" : [ "Coats & jackets" , "Suits & blazers" , "Skirts"]
            },
            {
                "id"  : 3,
                "name"  : "Shoes",
                "children" : [ "Boots" , "Flats" , "Ankle boots"]
            },
            {
                "id"  : 4,
                "name"  : "Bags",
                "children" : [ "Handbags" , "Backpacks" , "Clutches"]
            },
            {
                "id"  : 5,
                "name"  : "Accessories",
                "children" : [ "Jewelry" , "Belts" , "Scarves & Shawls"]
            },
            {
                "id"  : 6,
                "name"  : "Beauty",
                "children" : [ "Make Up" , "Face Care" , "Hand Care"]
            }
        ]
}

这是我的数组导入

const Women = AdminCatData.Women.map ((data) => {
    
  return(
    { 
      ...data,
    }
  )
  }

)

这是女性数组输出

{/*Women Tab*/}
            <Tab.Panel
              className={({ selected }) =>
              classNames(

                'focus:outline-none focus:ring-2 ring-offset-2 ring-offset-red-400 ring-white ring-opacity-60', 
                selected ? 'bg-white shadow' : 'text-white hover:bg-white/[0.12] hover:text-white'
              )
            }

            </Tab.Panel>
{/* End Women Tab */

}

女性标签输出目前我得到这样的输出。

女性标签期待输出我需要这样的输出

Answer 1

是这样的吗？

const Women = () => (
  {AdminCatData.Women.map((item, index) => <button key={item.id} onClick={() => console.log(index)}>{item.name}</button>)}
)

Answer 2

您可以尝试这样的操作：

const AdminCatData = {
  "Women": [
    {
      "id"  : 1,
      "name"  : "See All",
      "children" : [""]
    },
    {
      "id"  : 2,
      "name"  : "Clothes",
      "children" : [ "Coats & jackets" , "Suits & blazers" , "Skirts"]
    },
    {
      "id"  : 3,
      "name"  : "Shoes",
      "children" : [ "Boots" , "Flats" , "Ankle boots"]
    },
    {
      "id"  : 4,
      "name"  : "Bags",
      "children" : [ "Handbags" , "Backpacks" , "Clutches"]
    },
    {
      "id"  : 5,
      "name"  : "Accessories",
      "children" : [ "Jewelry" , "Belts" , "Scarves & Shawls"]
    },
    {
      "id"  : 6,
      "name"  : "Beauty",
      "children" : [ "Make Up" , "Face Care" , "Hand Care"]
    }
  ]
};

function App() {
  return (
    <div>
      {AdminCatData.Women.map((woman, index) => {
        return <p onClick={() => console.log(index)}>{woman.name}</p>
      })}
    </div>
  );
}

ReactDOM.render(<App/>, document.getElementById("root"));
