</div>我在使用 bootstrap-4 模式时有双滚动条。我已经尝试了所有可能的解决方案（使用 jQuery 和 css），但我无法达到我想要的结果。
如您所见，有两个滚动条。即使我在模式关闭时将正文溢出设置为自动，并且在模式打开时将溢出隐藏，也会出现一个滚动条，但它会向右移动到正文内容。由于我使用的是多个引导模态，在触发多个引导模态后，body上的modal-open类消失了。
【问题讨论】：
这可能会有所帮助。 ***.com/questions/16369718/… 感谢您的建议，但这不是我想要达到的结果 :) 【参考方案1】：您是否尝试将其应用到您的 CSS 文件中？
html
overflow(x, y): hidden;
【讨论】：
你能给我们一些代码吗？从那张截图很难看出。那些双滚动条在 html 上吧？ 我现在附上了代码sn-p。希望这有助于理解 应用此代码时，我的整个页面都缺少垂直滚动。【参考方案2】：这里的问题似乎是“modal-open”类，当您打开下一个模态时，它并不总是添加到body（我认为这是由您的 hide() 和 show() 动作同时触发引起的时间）。
正是该类将滚动条移至您的身体：
.modal-open
overflow: hidden;
也许我找到了一个解决方案，而无需触及您的功能。我的解决方案对计算机说：“Ehi，机器！每次在页面中有模态显示时，在 <body> 中放置一个类 modal-open”。
为此，我使用了模态事件，您可以在此处找到文档：https://getbootstrap.com/docs/4.0/components/modal/
我只在你的脚本中添加了这个，CSS 不是必需的：
$('.modal').on('shown.bs.modal', function (e)
$("body").addClass("modal-open");
);
$("div[id^='entry']").each(function()
var currentModal = $(this);
//click next
currentModal.find('.btn-next').click(function()
currentModal.modal('hide');
currentModal.closest("div[id^='entry']").nextAll("div[id^='entry']").first().modal('show');
);
//click prev
currentModal.find('.btn-prev').click(function()
currentModal.modal('hide');
currentModal.closest("div[id^='entry']").prevAll("div[id^='entry']").first().modal('show');
);
);
$('.modal').on('shown.bs.modal', function (e)
$("body").addClass("modal-open");

也许我找到了一个好的解决方案！为此，我清理了一些代码，以便您更好地了解发生了什么。我将 cmets 添加到我编写的每个函数中。请注意，为简单起见，我还将“data-dismiss”属性添加到下一个和上一个按钮。我删除了你的循环，因为这里没有必要，我只创建了一个 onClick 事件。我在 Windows 上使用 Firefox、Chrome 和 IE11 进行了测试，一切正常。
试一试，如果有不明白的地方，请在 cmets 中告诉我。 :)

谢谢，双滚动条的问题消失了，但是当模态内容大于正文内容时，正文内容向右移动。当模态内容小于正文内容时，同样的问题加滚动条出现又消失:( 嗯...你完全正确，我没有注意到，对不起。顺便说一句，这是一个有趣的行为。现在我得去上班了，但今晚我会试着了解这里发生了什么。 ;) 当然，工作愉快。希望你能弄清楚代码中发生了什么:) 我编辑了我的答案。这次我希望你觉得它有用:) 非常感谢，它工作得非常好。但是当我关闭模式时，整个屏幕变成空白。我想我自己能弄清楚。再次感谢你:)【参考方案3】：这就是我解决此问题的方法...当我打开/关闭模式时，我正在使用此 javascript 添加和删除 html 上的 modal-open。
jQuery('.modal').on('shown.bs.modal', function (e)
jQuery("html").addClass("modal-open");
);
jQuery('.modal').on('hide.bs.modal', function (e)
jQuery("html").removeClass("modal-open");
);
对我来说，html 需要是 modal-open，即提供 overflow: hidden;
隐藏滚动条的样式。
