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').val(); var phone     = $('#phoneNumber').val(); var address   = $('#address').val(); 

So far I have the code below but it will not validate or work. Im new to this, please help! Changing var to this:

var jsonObject =                  {                  firstName: firstName,                   lastName: lastName,                  phoneNumber:phoneNumber,                  address:address                 } 

in JSONlint i am getting this error:

Parse error on line 1: varjsonObject={
^ Expecting '{', '['

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);

It's called on Object Literal

I'm not sure what you want your structure to be, but according to what you have above, where you put the values in variables try this.

var formObject =  {"formObject": [                 {"firstName": firstName, "lastName": lastName},                 {"phoneNumber": phone},                 {"address": address},                 ]} 

Although this seems to make more sense (Why do you have an array in the above literal?):

var formObject = {    firstName: firstName    ... }
