Why eval() isn't working here to deserialize such a simple JSON object?

Question

Hi,

I am trying to use eval() function to deserialize this JSON text by using eval function.

  var personJSON = {"FirstName":"Burak","LastName":"Ozdogan","Id":"001"
,"Department":"Information Technologies"};

  var personBurakOzdogan = eval('(' + personJSON + ')');    

But I am getting this error:

*Microsoft JScript compilation error: Expected ']'*

Is there something that I skip which I cannot catch?

Thanks

Answer 1

What you have is not JSON text. It is already a JSON object. So you don't need to use eval at all. You can directly access and manipulate its properties:

alert(personJSON.FirstName);

Answer 2

you are not dealing with a string, but with a json object. You are trying to evaluate a json object as string to create a json object.

var personJSON = 
'{"FirstName":"Burak","LastName":"Ozdogan","Id":"001","Department":"Information Technologies"}';

var personBurakOzdogan = eval('(' + personJSON + ')');   

this should work, although it doesn't make to much sense. this makes more sense:

  var personBurakOzdogan = {"FirstName":"Burak","LastName":"Ozdogan","Id":"001","Department":"Information Technologies"};
