如何防止javascript弹出窗口滚动..？

Question

我在使用此Javascript弹出窗口时出现问题。它可以很好地期待一件重要的事情，当我在主屏幕上向下滚动页面时，如果我点击登录按钮，这个弹出窗口似乎隐藏在顶部。它不适合滚动。

我添加了截图以显示我的意思。第一个显示它看起来很好，另一个显示我向下滚动一点并按下按钮。

它似乎也隐藏了顶部的菜单栏..这是固定的

我不知道如何解决这些问题。有谁有想法？

<script src="js/jquery.avgrund.js"></script>
<script>
$(function() {
    $('#show').avgrund({
        height: 700,
        holderClass: 'custom',
        showClose: true,
        showCloseText: 'close',
        onBlurContainer: '.containerrr',
        template: '<section id="conntent">' +
        '<form form name="login" action="loginprocess.php" method="post"  accept-charset="utf-8">' +
        '<a href="Home_Page.php"><img src="images/logopop.png"></a>' +
        '<h1></h1>' + '<div>' + '<input type="text" name="email" placeholder="example@example.com" required id="username" />' + '</div>' + '<div>' + '<input type="password" name="password" placeholder="Password" required id="password" />' + '</div>' + '<div>' + '<input type="submit" id="submit" name="submit" value="Log In">' + '</div>' + '</form>' + '</section>'

    });
});
</script>

在页面标题和弹出窗口的容器中使用position: fixed。然后，您将能够滚动其他所有内容，这些元素将相对于浏览器窗口保持固定。
