javascript - javascript从json中的嵌套数组中打印一个值

问题描述

有人可以帮我从下面的 json 解析 action.keyword 的值。我只能解析到“命中”。

const rsp = `{ "took": 10, "hits": { "total": { "value": 520 } }, "aggregations": { "2": { "buckets": [{ "1": { "hits": { "total": { "value": 2 }, "hits": [{ "type": "doc", "score": null, "fields": { "action.keyword": [ "Start" ] }, "key": "TEST2", "doc_count": 4566 }] } } }, { "1": { "hits": { "total": { "value": 10 }, "hits": [{ "type": "doc", "score": null, "fields": { "action.keyword": [ "End" ] }, "key": "TEST3", "doc_count": 454 }] } } } ] } } }`

const obj = JSON.parse(rsp);
const recEvents = obj['aggregations']['2']['buckets'];
const act_key = recEvents['1']['hits']['hits'];
console.log(act_key);

解决方案

像这样

const act_key = recEvents[0]['1']['hits']['hits'][0]['fields']['action.keyword'];

const rsp = `{ "took": 10, "hits": { "total": { "value": 520 } }, "aggregations": { "2": { "buckets": [{ "1": { "hits": { "total": { "value": 2 }, "hits": [{ "type": "doc", "score": null, "fields": { "action.keyword": [ "Start" ] }, "key": "TEST2", "doc_count": 4566 }] } } }, { "1": { "hits": { "total": { "value": 10 }, "hits": [{ "type": "doc", "score": null, "fields": { "action.keyword": [ "End" ] }, "key": "TEST3", "doc_count": 454 }] } } } ] } } }`

const obj = JSON.parse(rsp);
const recEvents = obj['aggregations']['2']['buckets'];
const act_key = recEvents[0]['1']['hits']['hits'][0]['fields']['action.keyword'];
console.log(act_key);
