javascript - 如何使用javascript将对象放入另一个对象中

Question

var noOfChild=document.getElementById('btnInput').value;

            for(var i=1;i<=noOfChild;i++){
            createJSON();

            function createJSON() {
                alert('working')
                var jsonObj =[];
               var startId=1;
                $("span[id=childNo]").each(function() {
                    var idChildName='childName'+startId;
                    var childName=document.getElementById(idChildName).value;

                    var idDobChild='dobChild'+startId;
                    var dobChild=document.getElementById(idDobChild).value;

                    var idSchoolName='schoolName'+startId;
                    var schoolName=document.getElementById(idSchoolName).value;

                    var idClassSection='classSection'+startId;
                    var classSection=document.getElementById(idClassSection).value;
                    alert(childName);
                    var item = {};
                    item ["child_name"] = childName;
                    item ["child_DOB"] = dobChild;
                    item ["child_class"] = classSection;
                    item ["child_school_name"] = "KV_32";

                   // jsonObj.push("{'"+startId+"':['"+item+"']}");
                    jsonObj.push(item);
                    startId=startId+1;
                });
                var obj={
                    "1":jsonObj
                };
                console.log(obj);

我想要这样的对象:

{"1":{"child_name": "ytfy", "child_DOB": "1993-06-18", "child_class": "d", "child_school_name": "KV_32"}}

但我现在是这样的:

1:{child_name: "ytfy", child_DOB: "1993-06-18", child_class: "d", child_school_name: "KV_32"}

在我看来，这个实现更加简洁、美观。您唯一需要了解的是，通过调用 objectResult["1"] 您还创建了一个字段“1”

var object = {"childName":"foo", "childSurname":"foo"};
var objectResult = {}

objectResult["1"] = object;
console.log(objectResult);
