Instead of going JSON a json string and using $.parseJSON, I need to take my object and store it in a variable as string representing JSON.
(A library I'm dealing with expects a malformed JSON type so I need to mess around with it to get it to work.)
What's the best way to do this?
Most browsers have a native JSON object these days, which includes parse and stringify methods. So just try JSON.stringify({}) and see if you get "{}". You can even pass in parameters to filter out keys or to do pretty-printing, e.g. JSON.stringify({a:1,b:2}, null, 2) puts a newline and 2 spaces in front of each key.
JSON.stringify({a:1,b:2}, null, 2)
gives
"{\n \"a\": 1,\n \"b\": 2\n}"
which prints as
{
"a": 1,
"b": 2
}
As for the messing around part of your question, use the second parameter. From http://www.javascriptkit.com/jsref/json.shtml :
The replacer parameter can either be a function or an array of String/Numbers. It steps through each member within the JSON object to let you decide what value each member should be changed to. As a function it can return:
- A number, string, or Boolean, which replaces the property's original value with the returned one.
- An object, which is serialized then returned. Object methods or functions are not allowed, and are removed instead.
- Null, which causes the property to be removed.
As an array, the values defined inside it corresponds to the names of the properties inside the JSON object that should be retained when converted into a JSON object.
