i am newbie in JSON. i just started learning JSON before 30 mins.

i want to print JSON array in jquery. 

 $.ajax({
                url : '/exp/resp.php',
                type : 'POST',
                dataType : 'json',
              //  data : 'uname='+uname+'&pass='+pass,
                success : function (data)
                {
                    alert(data);

                }
            });

now it's printing abc,def,ghi,jkl,mno. so i want to print it separate like abc def ghi etc.. i referred this answer but it didn't help...

data is not a "JSON array". Even though the response is JSON-encoded data, jQuery will have parsed the data already. So data is just a normal JavaScript array. The question/problem itself has nothing to do with JSON. –  Felix Kling Oct 3 at 6:11

if data is an array then

alert(data.join(' '));

@pandit you can use the index to access it.. like data[0], data[1]... data[data.length - 1] –  Arun P Johny Oct 3 at 6:53
 
thanks.... and one more question that if i want to send json object from php file then how send? –  404 Not Found Oct 3 at 6:59
 
@pandit not sure... not a PHP guy... i think there is a json_encode call –  Arun P Johny Oct 3 at 7:08
 
@pandit Arun is right, you can convert an array into a json string with json_encode and you can convert an json string into an array using json_dncode... –  zzlalani Oct 3 at 7:54

Since your data is an array Check the following tutorial

Join the elements of an array into a string:

var fruits = ["Banana", "Orange", "Apple", "Mango"];
var energy = fruits.join();

The result of energy will be:

Banana,Orange,Apple,Mango

Have a look at this http://www.w3schools.com/jsref/jsref_join.asp

For your code use Arun P Johny's solutions

alert(data.join(' '));

Why not print something generic like:

JSON.stringify(data);

This should work with either an object or an array.
