jquery serialize not working on checkboxes

I have a jquery on some checkboxes and I am trying to serialize the values so I can get multiple selections in a PHP.

Here is my jquery:

<script type="text/javascript">
    jQuery(document).ready(function($) {
        $("input:checkbox").change(function() {
            if($(this).is(':checked')) 
            {
                    var color = $(this).val().serialize;
                    $(".itemMain").hide();
                    $(".indexMain").load('indexMain.php?color='+color);
            }
        });
    });
</script>

And here my PHP:

$color = $_GET['color'];

Before applying th serialize, everything was working fine but I couldn't have multiple selections. Now it just doesn't work at all with the serialize().

Any suggestions? Thanks!

Another solution that worked for me.

Simply specified in the name attribute of your field that you want a multiple value in other terms : an array 

<form action="" method="post" id="filters_form"">
    <input id="fieldNameText" value="value0" name="fieldNameText" type="text">                                  
    <input type="checkbox" name="myFieldName[]" id="myFieldName" value="value1"/>
    <input type="checkbox" name="myFieldName[]" id="myFieldName" value="value2"/>
</form>

The serialize() method var dataString = $("#filters_form").serialize(); will result in

fieldNameText=value0&myFieldName%5B%5D=value1&myFieldName%5B%5D=value2

If you send those data in post with AJAX you'll get this in php :

Ajax 

$.ajax({
    type: "POST",
    url: "yourFormURL",
    data: dataString,
    success: function(response) {
        //do something
    }
});

PHP

print_r($_POST);

/* Output :
Array ( [fieldNameText] => value0 [myFieldName] => Array ( [0] => value1 [1] => value2 )) 
*/

Rough solution can be, on click event of each checkbox you can store/append its value in a variable(or a hidden input field) in a comma separated form, and pass this variable to the color query string.
