I am looping through the following json. I get id and name fine, but when I do json.templates[i].dailyemails.length it always returns 0.

Here is my json:

{
   "templates":[
      {
         "id":"2c1d99d9b6b2fb417601d24c10c9b041a7d6f37b",
         "dailyemails":[
            "[email protected]",
            "[email protected]"
         ],
         "name":"Registration Report"             
      },
      {
         "id":"7d7cc642ca13cc4a998cad364dfe8e623fd95ae3",
         "dailyemails":[
            "[email protected]"
         ],
         "name":"Live Report"
      }

   ]
}

If this is JSON, that is a string, you have to parse it and work with a javascript object :

var obj = JSON.parse(json);

And then you may query obj.templates[i].dailyemails

$.each(data.templates,function(index,item){
    alert(item.dailyemails.length)
});

This should work just fine as seen in this live demo. Make sure that your actual JSON structure is the same as the one you have shown in your question.
