How to create a multi dimensional object or array in javascript or jquery

Question

I want to store the data in to multidimensional arrays or object and send the data to the controller. I have defined the object in javascript like

 var dynamicprofile = new Object();
 var certidarry = [];
 var trueorfalse = [];
 dynamicprofile.profilename = "certifications";
 $(".certclass").each(function (index, element) {
 certidarry.push(i);
 if (element.checked == false) {
 trueorfalse.push(false); 
 }
 else if (element.checked == true) {
 trueorfalse.push(true);
 }
 });
 dynamicprofile.idarray = certidarry;
 dynamicprofile.trueorfalse = trueorfalse;
 dynamicprofile.profilename = "projects";
 var projectidarry12 = [];
 var trueorfalsearry12 = [];
 $(".Projectsclass").each(function (index, element) { 
 projectidarry12.push(index); 
 if (element.checked == false) {
 trueorfalsearry12.push(false);
 }
 else if (element.checked == true) {
 trueorfalsearry12.push(true);
 }
 });
 dynamicprofile.idarray = projectidarry12;
 dynamicprofile.trueorfalse = trueorfalsearry12;

If the see the json content then it is displaying only the latest information. but it is not showing the content that is saved earlier. how can i save the content.

The problem is that you are overriding: dynamicprofile.profilename, dynamicprofile.idarray and dynamicprofile.trueorfalse.

Maybe you can try one of these solutions among others:

1.

 var dynamicprofile = new Object();
 var certidarry = [];
 var trueorfalse = [];
 dynamicprofile['certifications'] = {};
 $(".certclass").each(function (index, element) {
 certidarry.push(index);
 if (element.checked == false) {
 trueorfalse.push(false); 
 }
 else if (element.checked == true) {
 trueorfalse.push(true);
 }
 });
 dynamicprofile['certifications'].idarray = certidarry;
 dynamicprofile['certifications'].trueorfalse = trueorfalse;
 dynamicprofile['projects'] = {};
 var projectidarry12 = [];
 var trueorfalsearry12 = [];
 $(".Projectsclass").each(function (index, element) { 
 projectidarry12.push(index); 
 if (element.checked == false) {
 trueorfalsearry12.push(false);
 }
 else if (element.checked == true) {
 trueorfalsearry12.push(true);
 }
 });
 dynamicprofile['projects'].idarray = projectidarry12;
 dynamicprofile['projects'].trueorfalse = trueorfalsearry12;

 var dynamicprofile = [];
 var certidarry = [];
 var trueorfalse = [];
 $(".certclass").each(function (index, element) {
 certidarry.push(index);
 if (element.checked == false) {
 trueorfalse.push(false); 
 }
 else if (element.checked == true) {
 trueorfalse.push(true);
 }
 });
 dynamicprofile.push({ 
 profilename: "certifications",
 idarray: certidarry,
 trueorfalse: trueorfalse
 });
 var projectidarry12 = [];
 var trueorfalsearry12 = [];
 $(".Projectsclass").each(function (index, element) { 
 projectidarry12.push(index); 
 if (element.checked == false) {
 trueorfalsearry12.push(false);
 }
 else if (element.checked == true) {
 trueorfalsearry12.push(true);
 }
 });
 dynamicprofile.push({ 
 profilename: "projects",
 idarray: projectidarry12,
 trueorfalse: trueorfalsearry12
 });

u can do it in following way

 var a=new Array();
 for(vr i=0;i<10;i++)
 {
 a[i]=new Array();
 a[i][0]='value1';
 a[i][1]='value2';
 }

• Jonathan: yah i have found another way. I have taken another object var objname = {}; and for the first obj objname["cert"] and for the second object objname["projects"]. thanks for the answer
