How to fetch Dynamic keys from JavaScript Associative array?

Question

I have a JSON string which I then convert into JSON Object by using jQuery. The string in question given below:

  var json = [
      {
        "1240": [
          "Order1",
          "user1"
        ]
      }
    ]

Here key 1240 is Dynamic and I can't do something like json[0]["1240"] When I do something like:

for(var f in json )
      {
          alert(f);
      }

Then it returns "0"

How do I fetch 1240 here?

Of course it's 0 since it's json[0]. If you want to reach "1024", you need for(var i in json[0]) — Passerby

Because it's an array of objects.

Try this

    var json = [
      {
        "1240": [
          "Order1",
          "user1"
        ]
      }
];

for (var i = 0; i < json.length; i++)
{
  for(var f in json[i])
      {
          alert(f);
      }
}

try this also.

var json = [
      {
        "1240": [
          "Order1",
          "user1"
        ]
      }
];

for (var i in json)
{
  for(var f in json[i])
      {
          alert(f);
      }
}
