How do I use jQuery’s form.serialize but exclude empty fields

I would like to send all values from fields in a form using ajax without value from field “lastname” – how can I do that? My code:

<script>
    $(document).ready(function () {
        $('#other').click(function () {
            $.post("/Home/About", $("#target").serialize());
        });
    });
</script>

<form id="target" action="/Home/About" method="post">
    First name:
    <input type="text" name="firstname" id="firstname"><br>
    .....other fields.....
    Last name:
    <input type="text" name="lastname" id="lastname"><br>
</form>
<div id="other">Submit</div>

You can use the :not selector:

$.post("/Home/About", $("#target :not(#lastname)").serialize());
