JS Cookie存取值

JS Cookie存取值

代码附上：

 <script type="text/javascript"> //Cookie取值 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; } //Cookie设置值 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; } //调用设置 writeCookie ("myCookie", "my name", 24); //调用取值 alert (readCookie ("myCookie")); </script>
