[jQuery] Problem with radio/checkboxes on ajax post

[e2e]

Hi,

I use this function to submit my post requests. But now I have a
problem with radio buttons and checkboxes. It sends all button values
to server, so the last radio buttons' (even it's not checked) value
passes as value. checkboxes are same, even it's not checked, it sends
checked value.

$("form#profile_form").submit(function() {
                $("#users_profile h1").after('<div class="loading"></div>');
                $("#users_profile .errors").remove()
                var inputs = [];
                $(':input', this).each(function() {
                inputs.push(this.name + '=' + unescape(this.value));
                });
                $.ajax({
                type : "POST",
                data : inputs.join('&'),
                url : "tasks.php?task=updateprofile",
                success : function(msg) {
                        $("#users_profile .loading").remove();
                        if(msg == "ok") {
                                $("#profile_form").remove();
                                $("#users_profile h1").after('<div 
class="message m_info">Profile
updated!</div>');
                        } else {
                                $("#users_profile h1").after(msg);
                        }
                        }
                });
                return false;
        });
