Convert JS object to JSON string

Question

If I defined an object in JS with:

var j={\"name\":\"binchen\"};

How can I convert the object to JSON? The output string should be:

Answer 1

if you have a json string and it's not wrapped with [] then wrap it up first

var str = '{"city": "Tampa", "state": "Florida"}, {"city": "Charlotte", "state": "North Carolina"}';
str = '[' + str + ']';
var jsonobj = $.parseJSON(str);

OR

var jsonobj = eval('(' + str + ')');
console.log(jsonobj);
