Need Help With Json Array Print

I have a db query and a ajax script. my db query echo's out an array using json_encode and using ajax i am successful in catching that array but cannot print out the array materials. every time i attempt to print out the array objectOBJECT gets printed. Please help me.

Code snippets given below

This is my php code which echo the array

$sub_array_cat = array();
$id = $_POST['id'];
$check_if_sub_cat_exist = "SELECT sub_cat_name FROM sub_cat_table WHERE main_id='{$id}'";
$check_if_sub_cat_exist_query = mysql_query($check_if_sub_cat_exist,$connect);
if(!$check_if_sub_cat_exist_query){die('error '.mysql_error());}
if(mysql_num_rows($check_if_sub_cat_exist_query)>0)
{
while($out_d = mysql_fetch_assoc($check_if_sub_cat_exist_query))
{
$sub_array_cat[] = $out_d;
}
echo json_encode($sub_array_cat);

exit();
}//if(mysql_num_rows($check_if_sub_cat_exist_query)>0)
else{
echo "not found";
exit();
}

And this is my ajax script

function check_sub_cat(c){
var x = c;
$.ajax({
type: "POST",
url: "userpanel.php",
dataType:"JSON",
data: { id: c }
}).done(function(jjj)
{

var h = jjj
var lngth_of_array = jjj.length;
alert(h) // this gives out [object,Object]

});
}

I want to print the data. help needed

 

i hope this will help your problem
$.ajax({
type: "POST",
url: "userpanel.php",
dataType:"JSON",
data: { id: c }
}).done(function(jjj)
{

//var h = jjj
var lngth_of_array = jjj.length;
for(i=0;i<lngth_of_array;i++)
{
var h=jjj;
alert(h.YOUR_FIELD_NAME);
}
//alert(h) // this gives out [object,Object]

});

 

i guess this is because u use mysql_fetch_assoc. Try mysql_fetch_row.
When u encode associative array to json then u will get object in javascript.
