是否可以使用 Jasny Bootstrap 将 Off-canvas 菜单与模态功能结合起来？

Question

我在使用 Jasny Bootstrap

将 off-canvas 与模态功能结合时遇到问题

这些是我采取的步骤：

1. 我使用 jasny bootstrap 创建了一个非 canvas 菜单，它按预期工作 Off Canvas Only

2. 但是，当我添加模态功能时，将屏幕拉伸到 992px 宽度后，off-canvas 菜单会消失。此外，我无法通过在元素外部单击来关闭模式。 Modal functionality + Off-Canvas

我遇到的问题是 data-toggle="modal" 或 data-toggle="offcanvas" 我只能用其中之一。还有另一种添加两个数据切换的方法吗？或者更好：

What options do I have to use both an offcanvas menu with modal functionality?

    -webkit-box-shadow: inset 0 0 6px rgba(0,0,0,0.5);

Answer 1

不，modal 和 offcanvas 不应在同一个元素上使用。意想不到的事情会发生。

如果您只想使用 offcanvas 添加背景，最好手动添加，而不是使用模态插件。

在HTML中添加

<div class="backdrop">

与CSS

.backdrop {
  background: rgba(0, 0, 0, 0.5);
  position: fixed;
  top: 0;
  bottom: 0;
  width: 100vw;
  height: 100vh;
  z-index: 1040;
  display: none;
}

与使用 JavaScript 相比，显示和隐藏背景

$('.navmenu').on('show.bs.offcanvas', function() {
    $('.backdrop').fadeIn();
});

$('.navmenu').on('hide.bs.offcanvas', function() {
    $('.backdrop').fadeOut();
});

最后，向菜单添加关闭按钮是微不足道的

<a href="#" class="close" data-toggle="offcanvas" data-target=".navmenu">&times;</a>
