The json format cipher output is not string #53

What steps will reproduce the problem?
1. In the given example:
  var encrypted = CryptoJS.AES.encrypt("Message", "Secret Passphrase", { format: JsonFormatter });

    alert(encrypted); // {"ct":"tZ4MsEnfbcDOwqau68aOrQ==","iv":"8a8c8fd8fe33743d3638737ea4a00698","s":"ba06373c8f57179c"}

    var decrypted = CryptoJS.AES.decrypt(encrypted, "Secret Passphrase", { format: JsonFormatter });

    alert(decrypted.toString(CryptoJS.enc.Utf8)); // Message

The returned encrypted is always an object, though stringify function is right.

2. Seems encrypted in CryptoJS.AES.decrypt(encrypted, "Secret Passphrase", { 
format: JsonFormatter }) could be either json string or object, it works and 
get string output.

What is the expected output? What do you see instead?
CryptoJS.AES.encrypt with format option should return the format I want, for 
example json string.

What version of the product are you using? On what operating system?
The script in the given example.

Please provide any additional information below.
I tested the example in latest chrome.

It's actually expected behavior that "encrypted" will always be an object. More 
specifically, it will always be a CipherParams object. A CipherParams object 
gives you access to all the parameters used during encryption -- key, IV, salt, 
etc. When you use a CipherParams object in a string context, or if you 
explicitly call toString(), then it's converted to a string using your chosen 
format.

Thanks for your reply. I have to call toString() to get the json string. It's 
my mistake. The function alert automatically call toString() but I used 
console.log.
So this issue can be dismissed.
