Index value of Array

Question

I have a json file with contents like this:

{
     "aaa":{
         "status":"available",
         "classkey":"dotnet"
     },
     "bbb":{
         "ccc":{
             "com":"available",
             "net":"available",
             "info":"available",
             "org":"available"
          }
     }
}

Now I want to fetch the value of array by index (ex., xxx[0] like this not like xxx['aaa']). How do I do that?

Answer 1

You can't. Order is not guaranteed in json and most other key-value data structures. Furthermore you don't have an array, you have an object. Why use name-value pairs at all if you aren't going to use the names to access the values? Therein lies the power of json and other key-value data stores. If you need to access the values by integer indexes, then just use an array to store your data.

Answer 2

Actually you can use int index like an array in JSON, just try that:

var jsonObject = {
     "0":{
         "status":"available",
         "classkey":"dotnet"
     },
     "1":{
         "ccc":{
             "com":"available",
             "net":"available",
             "info":"available",
             "org":"available"
          }
     }
}

alert(jsonObject[0].status)
