creating json object with variables

Question

I am trying to create a json object from variables that I am getting in a form.

var firstName = $(\'#firstName\').val();
var lastName  = $(\'#lastName\').va         


        

Answer 1

if you need double quoted JSON use JSON.stringify( object)

var $items = $('#firstName, #lastName,#phoneNumber,#address ')
var obj = {}
$items.each(function() {
    obj[this.id] = $(this).val();
})

var json= JSON.stringify( obj);
