how to convert a JSon object to an array in Javascript

Question

I am returning array as

$array = array {
         'id' => 1,
         'name'=>krishna,
}
echo json_encode($array);
exit;

from an ajax call

How can I convert this json value to java script array?

This is my actual data

var data = [{
   "candidate_notes_id":"1",
    "candidate_id":"38",
    "subject":"test",
    "description":"t‌estestsete\netestes\n\n\nsteetet",
    "private":"0",
    "created_date":"2012-09-14 11:55:13",
    "updated_date":"2012-09-14 11:55:13",
    "updated_by":"admin"
  }] 

 var newArray = jQuery.parseJSON(data); 
 alert(newArray);
 return false;

result :

                      var newArray = JSON.stringify(data);
          var date_split = newArray.substr(1,newArray.length-2);
          var newData = date_split.replace('\n','<br>');
          var newArray = $.parseJSON(newData); 
          alert(newArray.candidate_notes_id);
          alert(newArray.candidate_id);
          alert(newArray.subject);
          alert(newArray.description);

Please be more specific. Do you want to have a Javascript array [1, "krishna"] or a Javascript object {id:1, name: "krishna"} ? — devnull69, Sep 14 '12 at 08:06

If you are using jQuery then you can use jQuery.parseJSON(YOUR_AJAX_RESPONSE_DATA); which will convert json to JS object

This is my actual data var data = [{"candidate_notes_id":"1","candidate_id":"38","subject":"test","description":"testestsete\netestes\n\n\nsteetet","private":"0","created_date":"2012-09-14 11:55:13","updated_date":"2012-09-14 11:55:13","updated_by":"admin"}] var newArray = jQuery.parseJSON(data); alert(newArray);return false; The Return value is null – krishnaraj Sep 14 '12 at 08:07
Control characters like \n need to be escaped. Look at your error console. "Bad control character in string literal". The `\n` have to be `\\n` – devnull69 Sep 14 '12 at 08:18
This is the ajax response? `{"candidate_notes_id":"1","candidate_id":"38","subject":"test","description":"t‌estestsete\netestes\n\n\nsteetet","private":"0","created_date":"2012-09-14 11:55:13","updated_date":"2012-09-14 11:55:13","updated_by":"admin"}` – Muthu Kumaran Sep 14 '12 at 08:19
I think you trying to get as array but they are in object. I modified your code and here it is, http://jsfiddle.net/25sjh/ Also you need to escape `\n` as `\\n`. I think you can do this in PHP side. – Muthu Kumaran Sep 14 '12 at 08:23
Ok. If my answer help you can set it as correct answer and give rep points. – Muthu Kumaran Sep 14 '12 at 10:39

You can parse it using

obj = JSON.parse(responseData); // replace `responseData` with your XHR response variable name

in your success callback function. Then convert it an array as follows

var myArray=[];
myArray[0]=obj.id;
myArray[1]=obj.name;

but first of all your

$array = array {
    'id' => 1,
    'name'=>krishna,
};

should be

$array = array (
    'id' => 1,
    'name'=>'krishna'
);

DEMO.

When i am using JSON.parse() its through the error like SyntaxError: JSON.parse: unexpected character – krishnaraj Sep 14 '12 at 08:17

And 'krishna' should be quotes, assuming it's not a constant. – Sherlock Sep 14 '12 at 08:20
