If You want to iterate over this object , You can use nested loop
angular.forEach(your_object.preAuthDiagnosisVOs, function(value, key) {
if (angular.isObject(value)) {
angular.forEach(value, function(value1, key) {
if (angular.isObject(value1)) {
angular.forEach(value1, function(value2, key) {
if (angular.isObject(value2)) {
angular.forEach(value2, function(value3, key) {
console.log(key + " : " + value3);
});
} else {
console.log(key + " : " + value2);
}
});
} else {
console.log(key + " : " + value1);
}
});
} else {
console.log(key + " : " + value);
}
});
And if you want just that active value just use
yourObject.preAuthDiagnosisVOs[0].active or yourObject.preAuthDiagnosisVOs[1].active
Hope this helps you . Thanks

I just validate your json format it has some syntactical issue. I have corrected this.
{
"preAuthDiagnosisVOs": [{
"preauthDiagnosisId": 165,
"diagnosisVO": {
"diagnosisId": 171,
"diagnosisCode": "Provisional",
"icdCode": {
"icdCodeId": 1,
"description": "OtherintestinalEscherichiacoliinfections",
"icdCode": "OtherintestinalEscherichiacoliinfections",
"icdCodeChapter": "Certaininfectiousandparasiticdiseases",
"icdCodeCode": "A04.4"
},
"active": false
},
"active": true
}, {
"preauthDiagnosisId": 166,
"diagnosisVO": {
"diagnosisId": 172,
"diagnosisCode": "Provisional",
"icdCode": {
"icdCodeId": 2,
"description": "Otherviralenteritis",
"icdCode": "Otherviralenteritis",
"icdCodeChapter": "Certaininfectiousandparasiticdiseases",
"icdCodeCode": "A08.3"
},
"active": false
},
"active": true
}]
}
Now to access active key . preAuthDiagnosisVOs is array to access this you have to iterate with angular forEach loop. For access active key of each index just iterate and get it or to get directly use object.preAuthDiagnosisVOs[0].active and object.preAuthDiagnosisVOs[1].active.
I think it might be help you. Thank you
