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);

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

Please look at an answered question ...

You will find how to convert a json to an array.

JSON to javaScript array

var array = [];
$.each(JSONObject, function(i, obj) {
    array.push([obj.id.value, obj.name.value]);
});

Answer 3

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'
);
