Konvertieren von Json-Format in ein anderes Json-Format von AngularJS

Question

Ich versuche, einen Fragebogen mit angularjs zu implementieren, also habe ich die folgende Antwort-Array, muss ich dieses Objekt-Array in JSON-Format wie die folgende Ausgabe konvertieren, So wie kann ich konvertieren Objekt-Array in JSON-Format?

var response=[{"questiongroup":1,"question":1,"response":"response1"}, 
        {"questiongroup":1,"question":2,"response":"response2"}, 
        {"questiongroup":1,"question":3,"response":"response3"}, 
        {"questiongroup":1,"question":4,"response":"response4"}, 
        {"questiongroup":1,"question":5,"response":"response5"}, 
        {"questiongroup":2,"question":6,"response":"response6"}, 
        {"questiongroup":2,"question":7,"response":"response7"}, 
        {"questiongroup":2,"question":8,"response":"response8"}, 
        {"questiongroup":2,"question":9,"response":"response9"}, 
        {"questiongroup":2,"question":10,"response":"response10"}]; 

gewünschter Ausgang

{"questiongroups": [ 
         { 
         "questiongroup": 1, 
         "question": [ 
          { 
          "question": 1, 
          "response":"response1" 
          }, 
          { 
          "question": 2, 
          "response":"response2" 
          }, 
          { 
          "question": 3, 
          "response":"response3" 
          }, 
          { 
          "question": 4, 
          "response":"response4" 
           }, 
          { 
           "question": 5, 
           "response":"response5" 
          }] 
         }, 
         { 
          "questiongroup": 2, 
          "question": [ 
           { 
           "question": 6, 
           "response":"response6" 
           }, 
           { 
           "question": 7, 
           "response":"response7" 
           }, 
           { 
           "question": 8, 
           "response":"response8" 
           }, 
           { 
           "question": 9, 
           "response":"response9" 
            }, 
           { 
            "question": 10, 
            "response":"response10" 
           }] 
          } 
         ] 
        } 

Answer 1

Die schnellste Lösung, die zu mir kam.

Reduziert die Antwort auf ein Objekt, bei dem die Fragengruppe die IDs der Arrays ist. Um dann wie gewünscht zurückzugeben, wurden die Schlüssel zum Generieren des Arrays zugeordnet und das Objekt mit dem Wert der Fragengruppe erstellt.

var response=[{"questiongroup":1,"question":1,"response":"response1"}, 
 
        {"questiongroup":1,"question":2,"response":"response2"}, 
 
        {"questiongroup":1,"question":3,"response":"response3"}, 
 
        {"questiongroup":1,"question":4,"response":"response4"}, 
 
        {"questiongroup":1,"question":5,"response":"response5"}, 
 
        {"questiongroup":2,"question":6,"response":"response6"}, 
 
        {"questiongroup":2,"question":7,"response":"response7"}, 
 
        {"questiongroup":2,"question":8,"response":"response8"}, 
 
        {"questiongroup":2,"question":9,"response":"response9"}, 
 
        {"questiongroup":2,"question":10,"response":"response10"}]; 
 

 
var questiongroups = response.reduce(function(groups, question){ 
 
    var group = groups[question.questiongroup] || []; 
 
    group.push({ 
 
    question: question.question, 
 
    response: question.response 
 
    }); 
 

 
    groups[question.questiongroup] = group; 
 
    
 
    return groups; 
 
}, {}); 
 

 
questiongroups = Object.keys(questiongroups).map(function (key) {return {questiongroup: key, question: questiongroups[key]}}); 
 

 
var object = { 
 
    questiongroups: questiongroups 
 
}; 
 

 
console.log(object);

var response=[{"questiongroup":1,"question":1,"response":"response1"}, 
 
        {"questiongroup":1,"question":2,"response":"response2"}, 
 
        {"questiongroup":1,"question":3,"response":"response3"}, 
 
        {"questiongroup":1,"question":4,"response":"response4"}, 
 
        {"questiongroup":1,"question":5,"response":"response5"}, 
 
        {"questiongroup":2,"question":6,"response":"response6"}, 
 
        {"questiongroup":2,"question":7,"response":"response7"}, 
 
        {"questiongroup":2,"question":8,"response":"response8"}, 
 
        {"questiongroup":2,"question":9,"response":"response9"}, 
 
        {"questiongroup":2,"question":10,"response":"response10"}]; 
 

 
var result = { 
 
\t "questiongroups": [], 
 
} 
 

 
var group = { 
 
\t "questiongroup": 1, 
 
    "question": [] 
 
} 
 

 
for (var i in response) { 
 

 
\t if (response[i].questiongroup != group.questiongroup) { 
 
    \t result.questiongroups.push(group); 
 
    group = { 
 
    "questiongroup" : response[i].questiongroup, 
 
    \t "question": [] 
 
    }; 
 
    } 
 
    
 
    var entry = { 
 
    "question" : { 
 
     "question" : response[i].question, 
 
     "response" : response[i].response 
 
    } 
 
    } 
 
    
 
    group.question.push(entry); 
 
} 
 

 
result.questiongroups.push(group); 
 

 
console.log(result);
