How to convert string separated by commas to array?

Possible Duplicate:

Store comma separate values into array

I have a string containing values separated with commas:

"1,4,5,11,58,96"

How could I turn it into an object? I need something like this

["1","4","5","11","58","96"]

JSON is *a textual serialization of data*. I have updated the question to reflect needing a *JavaScript array*. If you need the JSON *text representation* of this array, that is an additional step (and is achieved as shown in joeltine's answer). Update or clarify the question as needed. Also, remember to "accept" answers. — , Jan 12 '13 at 00:34

This will convert it into an array (which is the JSON representation you specified):

var array = myString.split(',');

If you need the string version:

var string = JSON.stringify(array);

be aware that `JSON.stringify` is not in IE6 or 7. – Matt Greer Jan 12 '13 at 00:22
it worked only with end_value=JSON.stringify(start_value); [probably because start_value was parsed from json]. thank you very much :) – Mindaugas Jakubauskas Jan 12 '13 at 00:24

wouldn't the string version be `var string = array.join(',');` – Nawlbergs May 30 '19 at 19:48

In JSON, numbers don't need double quotes, so you could just append [ and ] to either end of the string, resulting in the string "[1,4,5,11,58,96]" and you will have a JSON Array of numbers.
