Is there a way to retrieve the initial value from the second element within the JSON data?

Exploring JSON Data Collections

In my JSON data, I have two collections: FailedCount and SucceededCount.

{
 "FailedCount": [{
    "FailedCount_DATE_CURRENT_CHECK": "2016-11-30 10:40:09.0",
    "FailedCount_DATE__CURRENT__CHECK": "10:40:09",
    "FailedCount_MEAS_VALUE": 0
  }, {
    "FailedCount_DATE_CURRENT_CHECK": "2016-11-30 10:45:09.0",
    "FailedCount_DATE__CURRENT__CHECK": "10:45:09",
    "FailedCount_MEAS_VALUE": 0
  }, {
    "FailedCount_DATE_CURRENT_CHECK": "2016-11-30 10:50:09.0",
    "FailedCount_DATE__CURRENT__CHECK": "10:50:09",
    "FailedCount_MEAS_VALUE": 1
  }],
  "SucceededCount": [{
    "SucceededCount_MEAS_VALUE": 555
  }, {
    "SucceededCount_MEAS_VALUE": 547
  }, {
    "SucceededCount_MEAS_VALUE": 339
  }]
}

I am interested in retrieving the first value from the SucceededCount collection.

My attempt:

jsonObj.SucceededCount[0];

However, the result returned is not as expected: [object Object].

Answer №1

Give this a shot: 

jsonObject.CountOfSuccess[0].Count_MEAS_VALUE;

Let me know if you need more assistance.

Answer №2

Retrieve the property SucceededCount from your object and convert it into an array. Access the first element in this array SucceededCount[0] and then retrieve the specific property you are interested in 

SucceededCount[0].SucceededCount_MEAS_VALUE

var data = {
  "FailedCount": [{
    "FailedCount_DATE_CURRENT_CHECK": "2016-11-30 10:40:09.0",
    "FailedCount_DATE__CURRENT__CHECK": "10:40:09",
    "FailedCount_MEAS_VALUE": 0
  }, {
    "FailedCount_DATE_CURRENT_CHECK": "2016-11-30 10:45:09.0",
    "FailedCount_DATE__CURRENT__CHECK": "10:45:09",
    "FailedCount_MEAS_VALUE": 0
  }, {
    "FailedCount_DATE_CURRENT_CHECK": "2016-11-30 10:50:09.0",
    "FailedCount_DATE__CURRENT__CHECK": "10:50:09",
    "FailedCount_MEAS_VALUE": 1
  }],
  "SucceededCount": [{
    "SucceededCount_MEAS_VALUE": 555
  }, {
    "SucceededCount_MEAS_VALUE": 547
  }, {
    "SucceededCount_MEAS_VALUE": 339
  }]
};

console.log(data.SucceededCount[0].SucceededCount_MEAS_VALUE);
