Javascript 这种情况的解决方案是什么？

更改另一个模式时，“模式打开”类从主体中移除，打开的模式不能正确滚动Y轴

这是

请提出解决方案

代码：

JS:

它可以帮助你

$(document)
    .on('shown.bs.modal', '.modal', function () {
    $(document.body).addClass('modal-open')
});

工作对我来说似乎很好。你能用更多的细节来解释你的问题吗？我有另一个页面，在同一个过程中使用了更多的内容。当点击其中一个按钮时，一个模态打开类被添加到主体上，整个页面被溢出隐藏。由于此类原因，backpage页面滑动停止，但当您单击登录的注册while opened模式时，主体中打开的模式类将被删除，页面将向下滚动。我想滚动模态激活部分，而不是后身非激活部分。请提供一个有用的问题标题，提示问题的要点。@khushi，同时单击“关闭”按钮“模态打开”类应该被删除你得到答案了吗？在关闭按钮上点击事件，并从正文中删除类

模式打开

。你能在你编写的上述函数上添加该函数吗？
