Typically you include an <input type="hidden"> in the form, and set the value you want in the event handler before it gets submitted.

<form method="post" action="thing" id="sandwich"><fieldset>
    <input type="text" name="inputbox1" value="This is such a great form!" />
    <input type="hidden" name="jsremark" />
</fieldset></form>

<script type="text/javascript">
    document.getElementById('sandwich').onsubmit= function() {
        this.elements.jsremark.value= 'Secretly it aint that great';
        return true;
    }
</script>
