ASP.NET----实现点击按钮或链接弹出登录对话框

主要是利用遮罩的原理：

<!--默认让登陆窗体不显示-->
    <style type="text/css">
        #login
        {
            position: relative;
        }
    </style>
<!--窗体不显示执行结束-->

上述主要实现默认让id=“login”登录窗体隐藏

<!--点击登陆时弹出隐藏的登陆窗体-->
    <script type="text/javascript">
        $(document).ready(function () { $("#yz").click(function () { $("div#login").show(); }); });
    </script>
<!--脚本执行结束-->

以上主要是利用Jquery实现隐藏窗体的显示,具体标签大家自行命名,此处只为大概原理，当然还有很多好的方法代码。

以下为收集而来的例子：
