//添加cookie function addCookie(name,value,expires,path,domain){ var str=name+"="+escape(value); if(expires!=""){ var date=new Date(); date.setTime(date.getTime()+expires*24*3600*1000);//expires单位为天 str+=";expires="+date.toGMTString(); } if(path!=""){ str+=";path="+path;//指定可访问cookie的目录 } if(domain!=""){ str+=";domain="+domain;//指定可访问cookie的域 } document.cookie=str; } //取得cookie function getCookie(name){ var str=document.cookie.split(";") for(var i=0;i<str.length;i++){ var str2=str[i].split(”=”); if(str2[0]==name)return unescape(str2[1]); } } //删除cookie function delCookie(name){ var date=new Date(); date.setTime(date.getTime()-10000); document.cookie=name+”=n;expire=”+date.toGMTString(); }
