//document.cookie="name=Nicholas;domain=nczonline.net;path=/";
<script type="text/javascript">
        var cookie = document.cookie;
        // cookie 默认的有效期是 会话时间 session 关闭浏览器就失效
        var date = new Date();
        var timeStamp = date.getTime() + 60*60*1000;
        date.setTime(timeStamp)
        // 毫秒 +  14 * 24 * 60 * 60 * 1000
        console.log("expiresDate:",date);
        document.cookie ="name=david; expires="+date.toUTCString();
        console.log(cookie);
        document.write(document.cookie);
