jQuery ajax serialize only 2 fields

Question

I know how to serialize the whole form like in example below or one specific field of the form by just changing the line:

data: $('form').serialize(),

to

data: $('#input-field').serialize(),

.

$(document).on('input paste', '#soap', function () {
  $.ajax({
     type:'POST',
     url:'/soap',
     headers: {'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')},
     data: $('form').serialize(),
         success:function(data){
            $('input[id=msg]').val(data.msg);
         }
    });
});

But i want to serialize 2 input fields that have an id....how to do that?

Answer 1

Way 1: By comma separated selector you can serialize two fields together using following code

var seializedTwoFields = $('#input-field1,#input-field2').serialize();

Way 2: When you use the jQuery serialize() function, it simply turns your field into a string in the format a=1. So you can certainly apply this function to two fields and concatenate the result, with an & between them.

Please try this snippet.

var formfield1 = $('#input-field1').serialize();
var formfield2 = $('#input-field2').serialize();

var seializedTwoFields = formfield1+'&'+formfield2;

Answer 2

You can have a complete object from the serialized data like below:

var obj = {};
$('form').serializeArray().map(function (x) { obj[x.name] = x.value; });
