连接两个相同键的json对象

Question

我有两个具有相似键 question 的 json 对象。

var data = {"question":[{
    QuestionID : counter1,
QuestionText: question1, 
    Choices:[{ChoiceID:100,Choice:"Yes",NextQuestionID:counter},
             {ChoiceID:101,Choice:"No",NextQuestionID:counter}],
AnswerType: answer_type
}]};


var data1 = {"question":[{
    QuestionID : counter2,
QuestionText: question2, 
    Choices:[{ChoiceID:103,Choice:"Yes",NextQuestionID:counter},
             {ChoiceID:105,Choice:"No",NextQuestionID:counter}],
AnswerType: answer_type
}]};

我想将它们连接成一个带有“问题”键的 json 对象，值将是如下所示的数组

var final = {"question":[
{
    QuestionID : counter1,
QuestionText: question1, 
    Choices:[{ChoiceID:100,Choice:"Yes",NextQuestionID:counter},
             {ChoiceID:101,Choice:"No",NextQuestionID:counter}],
AnswerType: answer_type
},
{
QuestionID : counter2,
QuestionText: question2, 
    Choices:[{ChoiceID:103,Choice:"Yes",NextQuestionID:counter},
             {ChoiceID:105,Choice:"No",NextQuestionID:counter}],
AnswerType: answer_type
}
]};

我尝试了很多方法，下面的方法接近我的目的地，但它创建了数据数组和 data1 对象

var jsons = new Array();
jsons.push(data);
jsons.push(data1);

如果我可以连接每个索引包含对象的question:Object 和question:Array[2]，我的问题就会解决。最终输出为question:Array[3]

任何帮助将不胜感激。 提前致谢。

Answer 1

我解决了这个问题

var index = 0; // number of question
$.each(previousData.question,function(){
           finalArray[index] = previousData.question[index]; //contain array
           index++; //here index is number of question
 });

 finalArray[index] = data.question;
 data = {'question': finalArray }; // convert array to object

Answer 2

可以通过jquery进行合并

var final = $.merge(data, data1);

Answer 3

好吧，您的代码实际上是将两个对象推入一个列表，因此您可以得到一个对象列表。在您的情况下，第一个元素是数据，第二个元素是 data1。所以你实际上不会得到所需的结果。

既然你想要一个对象试试这个

/* assuming data and data1 are created and both have the key question */
var final = {'question': [data.question, data1.question] };

// or using the concat feature
var final = data.question.concat(data1.question);
