代码如下: script language=javascript!--function readCookie(name){ var cookieValue = ; var search = name + =; if(document.cookie.length 0) { offset = document.cookie.indexOf(search); if (offset != -1) { offset += search.length; end = docum

代码如下:

<script language="javascript">
<!--
function readCookie(name)
{
  var cookieValue = "";
  var search = name + "=";
  if(document.cookie.length > 0)
  { 
    offset = document.cookie.indexOf(search);
    if (offset != -1)
    { 
      offset += search.length;
      end = document.cookie.indexOf(";", offset);
      if (end == -1) end = document.cookie.length;
      cookieValue = unescape(document.cookie.substring(offset, end))
    }
  }
  return cookieValue;
}
function writeCookie(name, value, hours)
{
  var expire = "";
  if(hours != null)
  {
    expire = new Date((new Date()).getTime() + hours * 3600000);
    expire = "; expires=" + expire.toGMTString();
  }
  document.cookie = name + "=" + escape(value) + expire;
}
if ((readCookie('myCookie')) == "" || (readCookie('myCookie')) == undefined || (readCookie('myCookie')) == null) 
{
 writeCookie("myCookie", "my name", 24);
 window.location.reload();
 }
-->
</script>
