Convert array to Object by JSON.parse

Question

var arr=[];
arr['first']='val1';
arr['second']='val2';


var json=JSON.stringify(arr);
var obj=JSON.parse(json);  //obj is array

Can I return object {"first":"val1","second":"val2"} ?

PS: I read Convert Array to Object topic

I'm interested in this way of the function

Answer 1

If somebody has abused arrays like that , JSON does not help you. It will only serialize the numeric indices of Array objects, nothing else. Copy the properties by hand:

var obj = {};
for (var prop in arr)
    if (arr.hasOwnProperty(prop)) // don't copy enumerables from Array.prototype
        obj[prop] = arr[prop];

console.log(obj); // {"first":"val1","second":"val2"}

Answer 2

You shouldn't use an array to represent this:

Do this instead:

var obj = {first:"val1",second:"val2"};

Just define the object directly . Stringify and parsing is not necessary
