Answer 1

You can just trigger that function in you button’s onclick event..

<script type="text/javascript">
function del_cookie(name)
{
    document.cookie = name + '=; expires=Thu, 01-Jan-70 00:00:01 GMT;';
}
</script>
<INPUT TYPE=BUTTON OnClick="del_cookie('put name of cookie here');" VALUE="Clear Cookie"/>
