  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));

  {alert("No cookies found!");}
  else
  {alert("cookie变量:"+name+" 的值是 :"+value);}
