Is there any way to convert javascript object into JSON.

I can not use

JSON.stringify(<obj>)

Because there is no stringify method in the JSON object in the following link.

Link

Example:

var obj = {'x':1,'y':2}

Now if I'll run

console.log(JSON.stringify(obj));

Then I'm getting this error.

error: TypeError: Object # has no method 'stringify'

Well, the website overrides the actual JSON object with their own.

> JSON
> Object {toStr: function, quote: function}

Try using JSON.toStr(object)

It appears that some code/library has overridden the global JSON object. JSON.toStr is fine but if you want the original JSON objet back you can always create an invisible frame and use its global objects

OriginalJSON = (function() {
  var e = document.createElement('frame');
  e.style.display = 'none';
  var f = document.body.appendChild(e);
  return f.contentWindow.JSON;
})()

OriginalJSON.stringify({a: 1})

This is a technique that works for all global objects that has been overridden for some reason. As an alternative you can always copy only the stringify method

JSON.stringify = (function() {
  var e = document.createElement('frame');
  e.style.display = 'none';
  var f = document.body.appendChild(e);
  return f.contentWindow.JSON.stringify;
})()

// Now JSON.stringify is back
JSON.stringify({a: 1})

stringify method depends on your browser.

So if you cannot find JSON.stringify(), maybe the browser you're using is not patible to JSON API, you could include this library to make it there:

json2.js

Consider using external library, for example JSON 3 is a good choice.
