想要创建多维数组来读取javascript中的数组及其相关选项吗

我想在javascript中创建一个多维数组，在数组中获取问题及其相关选项

demoArray[i] = new Array();
var id=results.rows.item(i).del_ques_id;
demoArray[i]["question"] = results.rows.item(i).question;
demoArray[i]["id"] = results.rows.item(i).del_ques_id;

tx.executeSql('SELECT option,value,del_opt_id FROM delta_option WHERE del_ques_id='+results.rows.item(i).del_ques_id+' order by value desc', [], getOptionDetails, errorCB);

function getOptionDetails(tx,results){
    console.log("option query");
    var lent = results.rows.length;
    console.log("DEMO table: " + lent + " rows found.");
    for(var j=0;j<lent;j++){
        demoArray[i]=new Array();
        demoArray[i]["option"]=results.rows.item(j).option;
        }
}

这应该是我的数组结构 如何编码

var demoArray = [];
var ques = results.rows.item(i).question;
var id = results.rows.item(i).del_ques_id;
var quesObj = {};

var options = [];
var option = {};
//call your query and fill the options. I am assuming that you have multiple options for a question, Loop the next three lines of code for all the options of a particular question
option["option_name"] = "Some name result from your query";
option["option_id"] = "Some id result from your query";
//push this to your options
options.push(option);

//now create the quesObj consisting of ques,id and options
quesObj["question"] = ques;
quesObj["id"] = id;
quesObj["option"] = options;

//now add your quesObj to the demoArray
demoArray.push(quesObj);

现在，您可以循环上面的整个代码，向demoArray添加多个问题

结果是：

[
{
    question:question_string;
    id:question_id;
    option:[
        {
            option_name:option_string;
            option_id:option_id_string;
        },
        {
            option_name:option_string;
            option_id:option_id_string;
        }
        ....
 }
 {
        ..... Other Question Objects 
        ......
 } and so on

]

var questionArray=[]；
var问号=0；
var optionsArray=[]；
函数getQuestionDetails（发送、结果）{
var len=results.rows.length；
log（“演示表：“+len+”找到行”）；
for（var i=0；ii创建对象，但它不提供此多重数组
[
{
    question:question_string;
    id:question_id;
    option:[
        {
            option_name:option_string;
            option_id:option_id_string;
        },
        {
            option_name:option_string;
            option_id:option_id_string;
        }
        ....
 }
 {
        ..... Other Question Objects 
        ......
 } and so on

 var questionArray = [];
 var questionCounter = 0;
 var optionsArray = [];

    var len = results.rows.length;

       //console.log(results.rows.item(i).question);
       questionCounter = i;
       questionArray[i] = new Array();
       //var id = results.rows.item(i).del_ques_id;

      // console.log(questionArray[i]["question"]);

 function getOptionDetails(tx,results){

   var optLength = results.rows.length;

      qOptions[j]['optionValue'] = results.rows.item(j).value;
   } //EOC for
   console.log(questionArray[0]["qOptions"][0]["optionId"]);

   $scope.$apply(function() {
