这是我的代码。当我点击编辑按钮时，我想要一个模式。模式出现在我的页面中，当我单击关闭按钮时消失。但是使用模态它也显示滚动条。如何从我的代码中删除滚动条？

Answer 1

在引导程序 3 中，CSS 将第二个栏放在那里（模态类）。你可以像这样改变它：

.modal {
    overflow-y: auto;
}

Answer 2

您应该从引导类中隐藏滚动，然后删除margin-right.body

这里的css代码：

#modalElementId
{
  overflow: hidden;
}

在show.bs.modal事件中：

$('#modalElementId').on('show.bs.modal', function () {
  $('body').css("margin-right", "0px");
});

Answer 3

     .modal-open{
       margin-right:0px !important;
     }

Answer 4

您需要删除class modal-open中的body，检查：

$('#modalElementId').on('hidden.bs.modal', function (e) {
    $('body').removeClass('modal-open');
});

Answer 5

您可以设置模态体的高度

 .modal-body {
        max-height: 600px;
    }

Answer 6

在我的情况下，我想全屏显示图像，所以为了实现这一点，我必须删除模态填充（在滚动条上显示）并添加一些 CSS。例子：

<!-- Image Modal -->
<div class="modal fade p-0" id="zoomImageModal" tabindex="-1" role="dialog" aria-labelledby="zoomImageModal"
  aria-hidden="true">
  <div class="modal-dialog  modal-full" role="img">
    <div class="modal-content">
      <button type="button" class="close" data-dismiss="modal" aria-label="Close">
        <span aria-hidden="true">&times;</span>
      </button>
      <div class="m-auto">
        <img class="img-fluid" src="{{zoomPathImage}}" alt="zoomPathImage" [title]="zoomPathImage">
      </div>
    </div>
  </div>
</div>

风格：

.modal-full {
    min-width: 100%;
    margin: 0;
}

.modal-full .modal-content {
    min-height: 100vh;
}

注意：我使用的是 Bootstrap4
