如何用ID映射JSON文件

Question

如何使用包含每个记录ID的JSON文件映射和返回React中的值"Title“？例如：

{

"id001": {
      "Title": "Title-1",
      "Year": "1990",
      "Rated": "PG-13"
      },

"id002": {
      "Title": "Title-2",
      "Year": "1999",
      "Rated": "PG-13"
      },
      
...

}

太谢谢你了！

Answer 1

您需要先导入json文件。一些references

​

const a = {

"id001": {
      "Title": "Title-1",
      "Year": "1990",
      "Rated": "PG-13"
      },

"id002": {
      "Title": "Title-2",
      "Year": "1999",
      "Rated": "PG-13"
      },
      

}

const titleArr = Object.keys(a).map(function(key, index) {
  return a[key].Title;
});

console.log(titleArr)
