用javascript连接对象数组

我接受用户的提问，并使用Lawnchair将其保存在DOM中。声明的第一步

var dbQuestions = new Lawnchair({name:'questions'}, function(obj) { consol('questions initialized'); }); 

用户可以输入

问题文本

，

选项

，

NextQuestionID

，然后单击保存。然后每个问题转换为以下格式

var survey= {   
"name": "Internet Based survey",
"sortOrder":10,
"questions" : [
    { "QuestionID": "1", "SurveyID":1, "QuestionText":"Excuse me Sir/Madame, do you have 60 seconds to answer a few questions today?", "SortOrder":"10", "Choices": [{ "ChoiceID":"1", "Choice":"Yes", "NextQuestionID":"3", "InitiateSurvey":"true" }, 
                      { "ChoiceID":"2", "Choice":"No", "NextQuestionID":"1" }, 
                      { "ChoiceID":"3", "Choice":"What is it About?", "NextQuestionID":"2" }] 
    }]};

和保存

dbQuestions.save({key:'Q',value:survey},function(obj) {
    consol('Question Saved successfully');

});

保存第一个问题后，用户将输入下一个问题。上面的方法很好，但我需要以另一种方式保存。假设用户保存了3个问题，我想以下面的格式存储，这样我就可以轻松地访问这些问题

var survey = {  
"name": "Internet Based survey",
"sortOrder":10,
"questions" : [
    { "QuestionID": "1", "SurveyID":1, "QuestionText":"Excuse me Sir/Madame, do you have 60 seconds to answer a few questions today?", "SortOrder":"10", "Choices": [{ "ChoiceID":"1", "Choice":"Yes", "NextQuestionID":"3", "InitiateSurvey":"true" }, 
                      { "ChoiceID":"2", "Choice":"No", "NextQuestionID":"1" }, 
                      { "ChoiceID":"3", "Choice":"What is it About?", "NextQuestionID":"2" }] 
    }, 
    { "QuestionID": "2", "SurveyID":1, "QuestionText":"It is about a way to earn a little extra money with a side business", "SortOrder":"15", "Choices":[{ "ChoiceID":"1", "Choice":"Yes", "NextQuestionID":"3", "InitiateSurvey":"true" }, 
               { "ChoiceID":"2", "Choice":"No", "NextQuestionID":"1" }] 
    }, 
    { "QuestionID": "3", "SurveyID":1, "QuestionText":"Are you on the internet?", "SortOrder":"10", 
        "Choices":[{ "ChoiceID":"4", "Choice":"Yes", "NextQuestionID":"4" }, 
                   { "ChoiceID":"5", "Choice":"No", "NextQuestionID":"1" }] 
    }]};

所以我的问题是如何保存问题，每个问题将保存在“问题”属性下

提前谢谢。

你可以试试这个

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
