I want to loop through

• each object within lists and then
• each list within lists and count the number of objects within list
• if the number of objects within list = 3, I want to alert the value of each object

JSON

{
   "lists":[
    {
        "list":[
         {
            "value": "List 1 Value A"
         },
         {
            "value": "List 1 Value B"
         },
         {
            "value": "List 1 Value C"
         }
       ]
    },
    {
         "list":[
          {
             "value": "List 2 Value A"
          },
          {

   alert(list.value);
}

Try using:

$.each(response.lists, function (i, list) {
    if (list.list.length === 3) {
        $.each(list.list, function (j, item) {
            alert(item.value);
        });
    }
});
