Jquery stores username and password in cookie

Need to import jquery.js and jquery.cookie.js

<html>
<head>
<title>test cookie</title>
<script src="Scripts/jquery-1.4.1.min.js" type="text/javascript"></script>
<script src="Scripts/jquery.cookie.js" type="text/javascript"></script>
<script type="text/javascript">

  $(document).ready(function () {
    if ($.cookie("rmbUser") == "true") {
    $("#ck_rmbUser").attr("checked", true);
    $("#txt_username").val($.cookie("username"));
    $("#txt_password").val($.cookie("password"));
    }
  });

  //记住用户名密码
  function Save() {
    if ($("#ck_rmbUser").attr("checked")) {
      var str_username = $("#txt_username").val();
      var str_password = $("#txt_password").val();
      $.cookie("rmbUser", "true", { expires: 7 }); //存储一个带7天期限的cookie
      $.cookie("username", str_username, { expires: 7 });
      $.cookie("password", str_password, { expires: 7 });
    }
    else {
      $.cookie("rmbUser", "false", { expire: -1 });
      $.cookie("username", "", { expires: -1 });
      $.cookie("password", "", { expires: -1 });
    }
  };
</script>
</head>
<body>
  <div>
    用户名：<input type="text" id="txt_username"/><br />
    密码：<input type="text" id="txt_password"/><br />
    <input type="checkbox" id="ck_rmbUser"/>记住用户名和密码<br />
    <input type="submit" id="sub" value="登录" onclick="Save()"/>
  </div>

</html>
