JSON array parsing using jquery

Question

I have following JSON:

{
"category": {
    "category_identification": "1",
    "category_name": "C1",
    "image_one": "1.PNG",
    "image_two": "1_.PNG",
    "logo": "LOGO_1.PNG",
    "category_description": "DESCRIPTION"
},
"responseCode": "1"
}

I have to check if responseCode is 1 then have to display information from category (category_description, logo, etc.). I tried following code:

              $.each(data1, function(key, value) {
                    if (data1.responseCode == '1') {
                        alert(value.category_name)  
                    }
                });

where data1 is a JSON. I am getting undefined result.

Maybe just change value to data1.category? Like this:

$.each(data1, function(key, value) {
    if (data1.responseCode == '1') {
        alert(data1.category.category_name)  
    }
});

I wrote this answer because I don't see an array of JSONs, but only one JSON object. If that's the case, we can make it even simpler:

if (data1.responseCode == '1') {
    alert(data1.category.category_name)  
}

Yes you are right no need of each. I used your login but still getting undefined result. – sandipchandanshive Jan 30 '16 at 16:14
@Little tilli Is there any chance that you are missing `data1 = JSON.parse(data1)` before your code? – grabantot Jan 30 '16 at 16:34
Actually I am fetching JSON from ajax. – sandipchandanshive Jan 30 '16 at 16:36
@Littletilli but you have to use `JSON.parse()`, because even from AJAX you are returning plain text, not an object, so you have to parse it. – Nomce Jan 30 '16 at 16:39
So I suppose data1 is a string. You should convert it to object through JSON.parse(). – grabantot Jan 30 '16 at 16:39
here is my code : $.getJSON(value.URL + "/getCategory", {category_identification : catID}, function(data1) { if (data1.responseCode == '1') { alert(data1.category.category_name) } }); – sandipchandanshive Jan 30 '16 at 16:41
After adding data1 = JSON.parse(data1) I get: Uncaught SyntaxError: Unexpected token o – sandipchandanshive Jan 30 '16 at 16:46
