jQuery--添加与获取cookie

当网站需要记住密码时，当然最好的情况就是将账号密码存在本地，cookie信息是一个不错的选择，以下为jQuery操作cookie：

1、添加cookie：

      function addCookie(name, value, expiresHours) {

            var cookieString = name + "=" + escape(value);

            //判断是否设置过期时间 

            if (expiresHours > 0) {

                  var date = new Date();

                 date.setTime(date.getTime + expiresHours * 3600 * 1000);

                 cookieString = cookieString + "; expires=" + date.toGMTString();

             }

             document.cookie = cookieString;

         }

2、获取cookie：

    function getCookie(name) {

         var strCookie = document.cookie;

         var arrCookie = strCookie.split("; ");

         for (var i = 0; i < arrCookie.length; i++) {

                var arr = arrCookie[i].split("=");

                if (arr[0] == name) return arr[1];

          }

          return "";

     }

3、应用举例：

     1）HTML：

     <div>

         <p>账号：<input class="user_name" type="text" /></p>

         <p>密码：<input class="user_pwd" type="text" /></p>

         <p><input id="Button1" type="button" class="butLogin" value="登录" /></p>

     </div>

     2）jQuery：

     $(".user_name").bind("keyup click focus blur", function () {

            var username = $(this).val().toString();

            var userpwd = getCookie(username);

            $(".user_pwd").val(userpwd);

      });
