How to add ucwords and strtolower to this form

Question

I want "s.value" to be turned all to lowercase and then ucwords to it but I don't know how to do it since it's inside a form.

Basically I want to do something like this: ucwords(strtolower( s.value here ));

This is the form:

   <form role="search" method="get" id="searchform" action="http://chusmix.com/?s=" onsubmit="if (document.getElementById('s2').value.length > 5) window.location = action + '<php echo $city; ?>++++' + s.value; return false;" >

Thanks

<script type="text/javascript">

function ucwords (str) {
    return (str + '').replace(/^([a-z])|\s+([a-z])/g, function ($1) {
        return $1.toUpperCase();
    });
}

function strtolower (str) {
    return (str+'').toLowerCase();
}

</script>

<form role="search" method="get" id="searchform" action="http://chusmix.com/?s="  onsubmit="if (document.getElementById('s2').value.length > 5) window.location = action + '<?php echo $city; ?>++++' + ucwords(strtolower(s.value)); return false;" >

The javascript functions are from PHP.JS
