在 JS 中配对来自嵌套组的 JSON 值

Question

I am learning JSON and JavaScript and so far I am able to read the simple values. However, I do not know how to obtain lower level data pairs, such as in:

{ statusCode: 200,
content: '{"X":{"key":"k","name":"n", "nested":[{"nestedValue":"A","value":"111"},{"nestedValue":"B","value":"222"},{"nestedValue":"3","value":"333","bestValue":false}]}}',
 headers: {.....

I tried simple iterating but that does not work. I would like to get pairs such as A:111 and B:222.

Answer 1

 let content = { "X": { "key": "k", "name": "n", "nested": [{ "nestedValue": "A", "value": "111" }, { "nestedValue": "B", "value": "222" }, { "nestedValue": "3", "value": "333", "bestValue": false }] } }; let arr = content.X.nested; Object.entries(arr).forEach((entry) => { console.log(entry[0] + ' - ' + entry[1]); Object.entries(entry[1]).forEach(([key, val]) => { console.log(key + ' / ' + val); }) }) console.log(content.X); //obj console.log(content.X.key); //value console.log(content.X.nested); //array console.log(content.X.nested[0].nestedValue); //value console.log(content.X.nested[1].value); //value

I left the different console.log for you to see
