jQuery serialize does not register checkboxes

To build on azatoth’s genius answer, I have slightly extended it for my scenario:

    /* Get input values from form */
    values = jQuery("#myform").serializeArray();

    /* Because serializeArray() ignores unset checkboxes and radio buttons: */
    values = values.concat(
            jQuery('#myform input[type=checkbox]:not(:checked)').map(
                    function() {
                        return {"name": this.name, "value": false}
                    }).get()
    );
