Bootstrap 4移动导航栏从左侧滑动

Question

我正在使用最新版本的bootstrap.我自己尝试了各种各样的东西,之后我想我可能会在stackoverflow上找到一些东西.但善良没有得到这个东西.我的意思是它如何运作？

这是我的代码.我不会在这里添加任何自定义样式,因为它们没有真正起作用,反而他们创建了一些错误.

我也检查了这篇文章也Bootstrap - 如何从左边而不是从顶部滑动导航栏我尝试了所有的答案,但它不适合我.

Answer 1

你可以覆盖这样的过渡样式navbar-collapse......

演示

@media (max-width: 768px) {
    .navbar-collapse {
        position: absolute;
        top: 54px;
        left: 0;
        padding-left: 15px;
        padding-right: 15px;
        padding-bottom: 15px;
        width: 100%;
    }
    .navbar-collapse.collapsing {
        height: auto;
        -webkit-transition: left 0.3s ease;
        -o-transition: left 0.3s ease;
        -moz-transition: left 0.3s ease;
        transition: left 0.3s ease;
        left: -100%;
    }
    .navbar-collapse.show {
        left: 0;
        -webkit-transition: left 0.3s ease-in;
        -o-transition: left 0.3s ease-in;
        -moz-transition: left 0.3s ease-in;
        transition: left 0.3s ease-in;
    }
}

演示 - 从右侧
滑动演示 - 从左侧滑动

Answer 2

其实，你可以使用@Hrvoje Golcic的解决方案来实现从左滑动的效果。

我检查了您的代码并修复了一些问题。请检查以下代码片段。您可能需要定义更多 CSS 规则来设置导航栏的样式。

$(function(){
  // mobile menu slide from the left
  $('[data-toggle="slide-collapse"]').on('click', function() {
    $navMenuCont = $($(this).data('target'));
    $navMenuCont.animate({'width':'toggle'}, 280);
  });
})

    #navbarCollapse {
      position: fixed;
      top: 0;
      left: 0;
      z-index: 1;
      width: 280px; /*example + never use min-width with this solution */
      height: 100%;
      background: #000;
    }
