How to build a json object with a loop?

I'm trying to loop through a number of items, and create a json object. Each loop should be a new item on the object, but I'm having some issues doing it. It seems that only one set of items gets added, instead of multiple ones.

Here is my code:

jsonObj = {}

rows.each(function (index) {

    jsonObj[id] = $this.find('.elementOne').val();

    jsonObj[name] = $this.find('.elementTwo').text();



});

Here is what my json looks like:

{

    id: 3

    name: Stuff

},

Here is what I am trying to do:

{

    id: 1

    name: Stuff

},

{

    id: 2

    name: Stuff

},

{

    id: 3

    name: Stuff

}

There is no JSON here. Please don't confuse:

A JavaScript object (a data structure)

A JavaScript object literal (code to create such a data structure)

JSON (a data format based on a subset of object literal notation)

If you want an ordered list of objects (or any other kind of JavaScript data structure) then use an array. Arrays have a push method.

var myData = [];

rows.each(function (index) {

    var obj = { 

        id: $this.find('.elementOne').val(),

        name: $this.find('.elementTwo').text()

    };

    myData.push(obj);

});
