jquery - serializeArray() error

Question

im trying to pass an array as a string

$(document).ready(function(){
var args = {};
$('.radio').click(function(){
    var ob = $(this).siblings('select');
    $('#uploader-wrapper').html(pre_load());
    $('.radio').siblings('select').attr('disabled', 'disabled');
    ob.removeAttr('disabled');
    args[ob.attr('name')] = $(':selected', ob).text();
    loader( args.serializeArray() );
})
$('select[name=foo]').change(function(){
    var ob = $(this);
    $('#uploader-wrapper').html(pre_load());
    args[ob.attr('name')] = $(':selected', ob).text();
    loader( args.serializeArray() );
});
});

but i get an error

args.serializeArray is not a function

can anyone see what im doing wrong?

Answer 1

serializeArray is only available on jQuery objects. Since args is a vanilla object, use $.param:

loader($.param(args));

Answer 2

args is a normal javascript object, not a JQuery object.

From the docs,

This method can act on a jQuery object that has selected individual form elements, such as <input>, <textarea>, and <select>.
