Javascript操作Cookie[3]

用戶端操作Cookie主要使用document.cookie

1. 添加Cookie

       <script type="text/javascript">        //添加cookie        var value ="name=www";        var date = new Date();        date.setDate(date.getDay()+5);        document.cookie=value+"; expires="+date.toUTCString();    </script>

2. 讀取Cookie

       <script type="text/javascript">        alert(document.cookie);    </script>

3. 修改Cookie

       <script type="text/javascript">        //修改cookie,代碼與添加cookie一致        var value ="name=wwwLLLLooo";        var date = new Date();        date.setDate(date.getDay()+5);        document.cookie=value+"; expires="+date.toUTCString();    </script>

4. 刪除Cookie

       <script type="text/javascript">        //刪除Cookie.設定到期時間為昨天即可.        var cookieName ="password";        var date = new Date();        date.setDate(date.getDay()-1);        document.cookie=cookieName+"=deleted; expires="+date.toUTCString();    </script>
