Parse JSON string into an array

Question

I\'m trying to parse a string from JSON and turn those elements into an array in Javascript. Here\'s the code.

      var data = \"{\"fname\":\"Todd\",\"lname         


        

Answer 1

Most modern browsers have support for JSON.parse(). You would use it thusly:

  var dataJSON = '{"fname":"Todd","lname":"James","cascade":"tjames","loc":"res","place":"home", "day0":"0,1,2,3"}'; // You need to remove the trailing comma
  var data = JSON.parse(dataJSON);
  var getDay = data.day0;
  var getDayArray = getDay.split(",");

However, it might be better to modify whatever is generating the value for dataJSON, to return

  var dataJSON = '{"fname":"Todd","lname":"James","cascade":"tjames","loc":"res","place":"home", "day0":[0,1,2,3]}';
