Could you post more of the code? From what you've posted so far, it looks like what you're trying to do should work.tcigrand– tcigrand2015-04-07 18:04:30 +00:00Commented Apr 7, 2015 at 18:04

// JSON string returned from the server
var text = '{"items":[{"name":"itemX" ,"price":15},{"name":"itemY","price":25},{"name":"itemZ","price":20}]}';
// Convert the string returned from the server into a JavaScript object.
var object = JSON.parse(text);
// Accessing a specific property value of an item
console.log(object.items[0].name); //itemX
// Extract 'items' in to a separate array
var itemsArray = object.items;
console.log(itemsArray); //[itemObject, itemObject, itemObject]

If you're getting this as a string:
var json = JSON.parse(my_json_string)
Then,
var keys = Object.keys(json);
var values = [];
for(var i = 0; i < keys.length; i++){
values.push(json[keys[i]]);
}
