<script language="javascript"> 
  function setcookie(name, value) { //设置名称为name,值为value的cookie 
  document.cookie = name + "=" + value 
  document.location.reload(); 
  } 
  function setCookie() 
  { 
  document.cookie="a=abcd;" 
  document.cookie="b=5678;" 
  document.location.reload(); 
  } 
  var mycookie = document.cookie;  
  function readcookie(name) 
  { 
  var start1 = mycookie.indexOf(name + "="); 
  if (start1== -1) 
  alert("cookies not found"); 
  else 
  { 
  start=mycookie.indexOf("=",start1)+1;  
  var end = mycookie.indexOf(";",start); 
  if (end==-1) 
  { 
  end=mycookie.length;} 
  var value=unescape(mycookie.substring(start,end)); 
  if (value==null) 
  {alert("No cookies found!");} 
  else 
  {alert("cookie变量:"+name+" 的值是 :"+value);} 
  } 
  } 
</script> 
<input type="button" onclick="setCookie()" value="设置a=abcd;b=5678"> 
<input type="button" onclick="setcookie('a','qq')" value="设置a=qq"> 
<input type="button" onclick="readcookie('a');" value="读取a">
