Is there a good way to encode a JavaScript object as JSON?
I have a list of key value pairs...where the name is from a checkbox, and the value is either true or false based on whether the box is checked or not:
var values = {};
$('#checks :checkbox').each(function() { values[this.name]=this.checked; });
I want to pass these values into a JSON object so store into a cookie to render a table (Columns will be added according to what the user checks off).
Does anyone know a solution?

I think you can use JSON.stringify:
// after your each loop
JSON.stringify(values);
All major browsers now include native JSON encoding/decoding.
// To encode an object (This produces a string)
var json_str = JSON.stringify(myobject);
// To decode (This produces an object)
var obj = JSON.parse(json_str);
Note that only valid JSON data will be encoded. For example:
var obj = {'foo': 1, 'bar': (function (x) { return x; })}
JSON.stringify(obj) // --> "{\"foo\":1}"
Valid JSON types are: objects, strings, numbers, arrays, true, false, and null.
