JSON.parse Uncaught SyntaxError: Unexpected token o [duplicate]

Question

I have this JSON :

var data =  [{
    "ID":1,"Name":"Test",
    "subitem": [
        {"idenID":1,"Code":"254630"},
        {"idenID":2,"Code":"4566"},
        {"idenID":3,"Code":"4566"}
    ]
}];

console.log(JSON.parse(data)); //Uncaught SyntaxError: Unexpected token o 

How to de-serialize data to javascript object.

Answer 1

It already is an object ... of type Array. To access the Object:

var foo = data[0];

alert(foo.ID);

JSON.parse takes a String and parses it into an equivalent JavaScript value.

Answer 2

This is usable in Javascript. You need to parse JSON when your data is in String format and you get it from server side.

The purpose of JSON.parse is to convert to Javascipt Object Notation to use it. For example,

var str = "{"a":1,"b":2}";
var obj = JSON.parse(str); //obj = {a:1, b:2}
