Add JSON object to multidimensional array in javascript

Question

My aim is to add a JSON object based on certain conditions to an array which is then to be used to construct a WINJSList. I'm really struggling with accessing the elements of the list OR array after I have used the array.push method. I wanted to access these elements to ensure I am doing the addition right. Any help would be greatly appreciated. I have the following code

var names_Array = new Array;                
var names_List = new WinJS.Binding.List(names_Array);

if (condition) {
  if (condition) {
    names_List.push({ 
      name: "Joe Dowling", 
      image: "image/Joe Dowling.png", 
      ClientID: "1234" 
    });
  } else if (condition) {
    names_List.push({
      name: "Esteban Flamenco ", 
      image: "image/Esteban Flamenco.png", 
      ClientID: "6666" 
    });
  } else if (condition) {
    names_List.push({ 
      name: "Plain Jane ", 
      image: "image/Plain Jane.png", 
      ClientID: "0000" 
    });
                        }
console.log(names_Array);
console.log(names_Array[0]);
console.log(names_List);
console.log(names_List[0]);

I also tried:

var names_Array = new Array; 
if (condition) { 
  if (condition) {
    names_Array.push({
      name: "Joe Dowling", 
      image: "image/Joe Dowling.png", 
      ClientID: "1234" 
    });
  } else if (condition) {
    names_Array.push({
      name: "Esteban Flamenco ", 
      image: "image/Esteban Flamenco.png", 
      ClientID: "6666" 
    });
  } else if (condition) {
    names_Array.push({ 
      name: "Plain Jane ", 
      image: "image/Plain Jane.png", 
      ClientID: "0000" 
    });
  }

  var names_List = new WinJS.Binding.List(names_Array);

In the console I either get undefined or [object object]

For WinJS.Binding.List, refer documention here.

There are couple of issues with code:

• WinJS List initializes itself with the array passed to the constructor. After that if the array is modified, changes do not propogate to the winjs list.
• To access element at index, use list.getAt(index)

this code should work:

var data = []; 
data.push({
    name: "Joe Dowling",
    image: "image/Joe Dowling.png",
    ClientID: "1234"
});
data.push({
    name: "Esteban Flamenco ",
    image: "image/Esteban Flamenco.png",
    ClientID: "6666"
        });
data.push({
    name: "Plain Jane ",
    image: "image/Plain Jane.png",
    ClientID: "0000"
});

var list = new WinJS.Binding.List(data);
var item = list.getAt(0);
console.info(JSON.stringify(item))
