How to read data from nested JSON structure in protractor - json

Question

Below is my code and I want to extract data under "specs" part like description, status etc. however I'm getting undefined when I capture the data and print it in the console. I have tried
let web = JSON.parse(jsondata);
let TestSuite = web["suite1"]["description"]
and this is providing data in console however, when I use this,
let id = web["suite1"]["specs"]["id"]
its gives undefined. Please help!
{
"suite1": {
"id": "suite1",
"description": "Login",
"fullName": "Login",
"failedExpectations": [],
"status": "finished",
"specs": [
{
"id": "spec0",
"description": "Should able to login into the Distribution management Webpage",
"fullName": "Login Should able to login into the Distribution management Webpage",
"failedExpectations": [
{
"matcherName": "",
"message": "",
"stack": "",
"passed": false,
"expected": "",
"actual": ""
}
],
"passedExpectations": [],
"pendingReason": "",
"started": "2018-09-06T06:57:42.740Z",
"status": "failed",
"duration": "7 secs",
"stopped": "2018-09-06T06:57:49.255Z",
"browserLogs": []
}
]
} }

Answer 1

JSON.parse(JSON.stringify(json)).suite1.specs[0].id

Answer 2

specs contains an array of objects. First, you need to get the object from the array and then get a value of the object.
Try this:
let id = web["suite1"]["specs"][0]["id"]
OR
let id = web.suite1.specs[0].id
Hope this will work.

Answer 3

When you do ["suite1"]["specs"], you select array. You need an index, which is the 0-th one in this case.
You can check that by typing Object.prototype.toString.call( data["suite1"]["specs"]).
You can try with:
data["suite1"]["specs"][0]["id"]
Or use the object property notation
data["suite1"]["specs"][0].id
