Javascript converts xml to a json object

Parse XML using JavaScript, and then generate JSON Based on the DOM tree

JavaScript: how to convert a JSON object to a JSON string

1. Returns a string.
Var myObjectInJSON = myObject. toJSONString (); // This method is not available either.
Var jsonStr = JSON. stringify (obj );
Var jsonStr = jQuery. stringifyJSON (obj); // without this method, mislead me

2. Convert to json object
Var bToObj = JSON. parse (B );
JQuery. parseJSON (json );

Var c = '{"name": "Mike", "sex": "female", "age": "29 "}';
Var jsonObj = eval ("(" + c + ")");
