                    }
                ]
            },
            {
                "category_name": "fountain",
                "image": "images/0001.jpg",
                "type": [
                    {
                        "type": "small"
                    },
                    {
                        "type": "large"
                    }
                ]
            }
        ]
    }
]

If once the name is matched to Thums Up , is it possible to retrieve the category_name

can , bottle and fountain in my case ??

I have tried below , but could't able to continue once the name is matched ??

Could you please help me retriving the category_name for Thumps Up .

var result = JSON.stringify(retdata);



for(var i=0;i<result.length;i++)
        {
            if(i.name="Thums Up")
            {

            }
        }

You want `JSON.parse` not `JSON.stringify`. `.parse` will turn you JSON (string) into a javascript object. — Matt Burland, May 28 '14 at 18:28

you have array and then in array item there is another array, you need to do like this:

$.each(retdata,function(index,item){

$.each(item,function(index1,item1){

    console.log(item1);
});
    console.log(item);

});

so again do i need to use $.each on item1 to get the cateory names of ThumpsuP ?? – user3674364 May 28 '14 at 18:38
@user3674364: `category` contains an array. You have to iterate over it explicitly or use something like http://api.jquery.com/jquery.map/, depending on what exactly you want to do. – Felix Kling May 28 '14 at 18:39
yes @FelixKling is right in Category there is another array – Ehsan Sajjad May 28 '14 at 18:41
so you will have to write another each or use map inside second each – Ehsan Sajjad May 28 '14 at 18:43
