jquery 代码：
<script type="text/javascript" src="js/jquery-1.8.3.min.js"></script>
<script type="text/javascript" src="js/jquery.cookie.js"></script>
<script type="text/javascript">
$(function(){
//记住密码
if ($.cookie("rememberme") == "true") {
$("#rememberme").prop("checked", true);
$("#username").val($.cookie("username"));
$("#password").val($.cookie("password"));
}
$("#login").click(function(){
var username = $("#username").val();
var password = $("#password").val();
//设置cookie记住密码
if ($("#rememberme").prop("checked") == true) {
$.cookie("rememberme", "true", { expires: 7 }); // 存储一个带7天期限的 cookie
$.cookie("username", username, { expires: 7 });
$.cookie("password", password, { expires: 7 });
}else {
$.cookie("rememberme", "false", { expires: -1 }); // 删除 cookie
$.cookie("username", '', { expires: -1 });
$.cookie("password", '', { expires: -1 });
}
});
});

UserName:<input type="text" id="username" name="username" ><br>
PassWord:<input type="password" id="password" name="password"><br>
<input type="checkbox" name="rememberme" id="rememberme"> 记住密码一个周（<font color="red">公共场合慎用</font>）<br>
<input type="button" id="login" value="login"> <br>
<a href="regist.do">注册</a>
