  • JSON is a string. "JSON Array" is not a thing. What you have is an array of objects, that you want to convert to an array based on a property of those objects. – Niet the Dark Absol Apr 15 '14 at 15:35
  • What's the problem? You don't know how to use a `for` loop? or you don't know how to add items to a new Array? – cookie monster Apr 15 '14 at 15:40

I'd use Array.prototype.map:

var new_array = arr.map(function(e) {
    return e.sw;
});

Don't forget to get the actual JavaScript array from the JSON string with JSON.parse (as an example).
