如何从量角器中的嵌套JSON结构读取数据

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
