Javascript To Asp need help with theme code

this is the code that i have to change my style sheets, but i was wondering if it is easily ported to asp, since my pages are all .aspx

<script type="text/javascript"><script type="text/javascript" ><!--var style_cookie_name = "style" ;var style_cookie_duration = 30 ;function switch_style ( css_title ){  var i, link_tag;  for (i = 0, link_tag = document.getElementsByTagName("link");    i < link_tag.length ; i++ ) {    if ((link_tag[i].rel.indexOf( "stylesheet" ) != -1) &&      link_tag[i].title) {      link_tag[i].disabled = true;      if (link_tag[i].title == css_title) {        link_tag[i].disabled = false;      }    }    set_cookie( style_cookie_name, css_title,      style_cookie_duration );  }}function set_style_from_cookie(){  var css_title = get_cookie( style_cookie_name );  if (css_title.length) {    switch_style( css_title );  }}function set_cookie ( cookie_name, cookie_value,    lifespan_in_days, valid_domain ){    var domain_string = valid_domain ?                       ("; domain=" + valid_domain) : '';    document.cookie = cookie_name +                       "=" + encodeURIComponent( cookie_value ) +                       "; max-age=" + 60 * 60 *                       24 * lifespan_in_days +                       "; path=/" + domain_string;}function get_cookie ( cookie_name ){    var cookie_string = document.cookie;    if (cookie_string.length != 0) {        var cookie_value = cookie_string.match (                        '(^|[\s]*' +                        cookie_name +                        '=([^;]*)' );        return decodeURIComponent ( cookie_value[2] );    }    return '';}//--></script>

no clues?
