jquery实现界面无刷新加载登陆注册

官网的登陆注册每次要跳转到另一个界面，能不能做一个简单的，在界面弹出一个框框登陆，我想了想做了这么一个案例，大家来看看成不成

贴上代码，实现了在同一个弹出窗上加载了登陆注册功能！可自由点击！当然样式丑了一些！还请见谅！demo在下面

后面更上js，记得要把jquery给加上哦！红色区域的代码负责登陆注册点击切换的事件，在代码点击方法加上黄色代码可在点击后加载到当前界面！

<script type="text/javascript">
 $(function () {
 H_login = {};
 H_login.openLogin = function () {
 $('.login-header a').click(function () {
 switchTag('_xka', '_xka_list', 1, 2, 'conxk1', 'conxk2');
 $('.js_login').show();
 $('.login-bg').show();
 });
 $('.login-header1 a').click(function () {
 switchTag('_xka', '_xka_list', 2, 2, 'conxk1', 'conxk2');
 $('.js_login').show();
 $('.login-bg').show();
 });
 };
 H_login.closeLogin = function () {
 $('.close-login').click(function () {
 $('.js_login').hide();
 $('.login-bg').hide();
 });
 };
 H_login.loginForm = function () {
 };
 H_login.run = function () {
 this.closeLogin();
 this.openLogin();
 this.loginForm();
 };
 H_login.run();
 });
 function switchTag(tag, content, k, n, stylea, styleb) {
 for (i = 1; i <= n; i++) {
 if (i == k) {
 document.getElementById(tag + i).className = stylea;
 document.getElementById(content + i).className = "showbox"

 } else {
 document.getElementById(tag + i).className = styleb;
 document.getElementById(content + i).className = "hidden"
 }
 }
 };

 function ajaxlogin() {
 var username = $("#logusername");
 var usernameValue = $("#logusername").val();
 var password = $("#logpassword");
 var passwordValue = $("#logpassword").val();
 alert(usernameValue + passwordValue);
　　　　 window.location.reload();
 }

 function ajaxzhuce() {
 var usernameValue = $("#UserName").val();
 var passwordValue = $("#Password").val();
 var realNameValue = $("#RealName").val();
 var telephoneValue = $("#Telephone").val();
 var emailValue = $("#Mail").val();
 alert(usernameValue + passwordValue + realNameValue + telephoneValue + emailValue);
　　　　 window.location.reload();
 }
</script>
