登录时简单的记住密码和自动登录功能实现

$(document).ready(function(){            //Login Aciton            $("#login").bind("click", function () {                var username = $("#username").val();                var password = $("#password").val();                if(username == ""){                    alert("请输入用户名！");                    return;                }                if(password == ""){                    alert("请输入密码！");                    return;                }                <%--var s = "";--%>                <%--s += "{";--%>                <%--s += "username:'" + username + "',password:'" + password;--%>                <%--s += "'}";--%>                <%--arr = eval('(' + s + ')');--%>                <%--$.post("<%=request.getContextPath()%>/login.asp", arr, function(data){--%>                    <%--if(data == 1){--%>                        <%--location.replace("<%=path %>/page/index.jsp");--%>                    <%--}else{--%>                        <%--location.replace("<%=path %>/page/fail.jsp");--%>                    <%--}--%>                <%--});--%>                $("#loginForm").submit();   //form表单提交            });            if ($.cookie("automaticLogin") == "true") {                $("#automaticLogin").attr("checked", true);                $("#rememberMe").attr("checked", true);                $("#username").val($.cookie("usernameCookie"));                $("#password").val($.cookie("passwordCookie"));                $("#login").click();            }            if ($.cookie("rememberMe") == "true") {                $("#rememberMe").attr("checked", true);                $("#username").val($.cookie("usernameCookie"));                $("#password").val($.cookie("passwordCookie"));            }            //Automatic Login Checkbox            $("#automaticLogin").bind("click", function () {                if($(this).is(":checked") == true){                    // 存储一个带7天期限的 cookie                    $.cookie("automaticLogin", "true", { expires: 7 });                    $.cookie("rememberMe", "true", { expires: 7 });                    $.cookie("usernameCookie", $("#username").val(),{expires:7});                    $.cookie("passwordCookie", $("#password").val(),{expires:7});                }else{                    $.cookie("automaticLogin", "false", { expires: -1 });                }            });            //Remember Password Checkbox            $("#rememberMe").bind("click", function () {                if($(this).is(":checked") == true){                    // 存储一个带7天期限的 cookie                    $.cookie("rememberMe", "true", { expires: 7 });                    $.cookie("usernameCookie", $("#username").val(),{expires:7});                    $.cookie("passwordCookie", $("#password").val(),{expires:7});                }else{                    $.cookie("automaticLogin", "false", { expires: -1 });                    $.cookie("rememberMe", "false", { expires: -1 });                    $.cookie("usernameCookie", '', { expires: -1 });                    $.cookie("passwordCookie", '', { expires: -1 });                }            });        });

因为用到cookie所以要导入jquery.cookie.js
