如何使用 for 循环访问数组中的每个 json 对象？

  • 772
{
  "item1" : [{"index":"1"},{"id":"1","name":"npm","result":"expected text1"},{"id":"2","name":"yarn","result":"expected text2"},{"id":"3","name":"pnpm","result":"expected text3"}],
  "item2":  [{"index":"2"},{"id":"1","name":"npm","result":"expected text1 for item2"},{"id":"2","name":"yarn","result":"expected text2 for item 2"},{"id":"3","name":"pnpm","result":"expected text3 for item 2"}]

}

我想使用 for 循环访问 item1 和 item2？我该怎么做？

    const data = {
  "item1": [
    { "index": "1" },
    { "id": "1", "name": "npm", "result": "expected text1" },
    { "id": "2", "name": "yarn", "result": "expected text2" },
    { "id": "3", "name": "pnpm", "result": "expected text3" }
  ],
  "item2": [
    { "index": "2" },
    { "id": "1", "name": "npm", "result": "expected text1 for item2" },
    { "id": "2", "name": "yarn", "result": "expected text2 for item 2" },
    { "id": "3", "name": "pnpm", "result": "expected text3 for item 2" }
  ]
};

for (const key in data) {
  for (const obj of data[key]) {
    console.log(obj);
  }
}
