我正在使用Bootstrap 4文档中的offcanvas实验代码,但是当您在菜单外单击时,它不是设计为关闭的,这是我真的希望这样做。

我已经尝试了Web上的多个jquery代码段,但是它们利用了bootstrap的.collapse,并且在编辑它们以包含自定义.offcanvas-collapse类时不起作用。

<nav class="navbar fixed-top navbar-dark bg-dark">
      <button class="navbar-toggler p-0 border-0" type="button" data-toggle="offcanvas" data-target="#offcanvasNav" aria-controls="navbarResponsive" aria-expanded="false" aria-label="Toggle navigation">
            <i data-feather="menu"></i>
          </button>
            <a class="navbar-brand" href="#">Sleight of Word</a>
            <button class="navbar-toggler p-0 border-0" type="button" data-toggle="searchBar">
              <i data-feather="search"></i>
            </button>
            <form class="form-inline my-2 my-lg-0 d-none">
              <input class="form-control mr-sm-2" type="text" placeholder="Search" aria-label="Search">
              <button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>
            </form>

          <div class="navbar-collapse offcanvas-collapse" id="offcanvasNav">
            <ul class="navbar-nav mr-auto">
              <li class="nav-item active">
                <a class="nav-link" href="#">Dashboard <span class="sr-only">(current)</span></a>
              </li>
              <li class="nav-item">
                <a class="nav-link" href="#">Notifications</a>
              </li>
              <li class="nav-item">
                <a class="nav-link" href="#">Profile</a>
              </li>
              <li class="nav-item">
                <a class="nav-link" href="#">Switch account</a>
              </li>
              <li class="nav-item dropdown">
                <a class="nav-link dropdown-toggle" href="#" id="dropdown01" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">Settings</a>
                <div class="dropdown-menu" aria-labelledby="dropdown01">
                  <a class="dropdown-item" href="#">Action</a>
                  <a class="dropdown-item" href="#">Another action</a>
                  <a class="dropdown-item" href="#">Something else here</a>
                </div>
              </li>
            </ul>
            <form class="form-inline my-2 my-lg-0">
              <input class="form-control mr-sm-2" type="text" placeholder="Search" aria-label="Search">
              <button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>
            </form>
          </div>
        </nav>

.offcanvas-collapse {
    position: fixed;
    top: 56px; /* Height of navbar */
    bottom: 0;
    right: 100%;
    width: 240px;
    padding-right: 1rem;
    padding-left: 1rem;
    overflow-y: auto;
    visibility: hidden;
    background-color: purple;
    transition: visibility .2s ease-in-out, -webkit-transform .2s ease-in-out;
    transition: transform .2s ease-in-out, visibility .2s ease-in-out;
    transition: transform .2s ease-in-out, visibility .2s ease-in-out, -webkit-transform .2s ease-in-out;
  }

  .offcanvas-collapse.open {
    visibility: visible;
    -webkit-transform: translateX(100%);
    transform: translateX(100%);
  }


$(function () {
  'use strict'

  $('[data-toggle="offcanvas"]').on('click', function () {
    $('.offcanvas-collapse').toggleClass('open')
  })
})

$(document).on('click',function(){
    $('.offcanvas-collapse').offcanvas-collapse('hide');
})


我希望这将使Offcanvas导航可以通过菜单按钮切换(打开和关闭),并且在菜单外部单击时可以关闭导航,但是在导航外部单击则无济于事。

最佳答案

$(document).on('click',function(){
  $('.offcanvas-collapse').toggleClass('open');
})


单独,将在文档中所有具有类open的元素上切换类offcanvas-collapse。如果元素具有类,则将其删除,否则将添加它。

如果将以上内容与其他代码段结合使用:

$(function () {
  'use strict'

  $('[data-toggle="offcanvas"]').on('click', function () {
    $('.offcanvas-collapse').toggleClass('open')
  })
})


...,每次单击[data-toggle="offcanvas"]时,两个代码段都在运行(因为您单击了[data-toggle="offcanvas"],但同时也单击了document(因为click事件一直冒泡直至document,除非因此,offcanvas-collapse类被切换了两次,因此看起来好像不起作用。

这显然不是您要追求的。

您可能想要:


单击open时,在.offcanvas-collapse元素上切换类[data-toggle="offcanvas"],而不允许该click事件传播到document
当在文档中的任何位置单击时,从open元素中删除(而不切换)类.offcanvas-collapse。如果使用toggle,则关闭offcanvas时,click中的document将打开它,这可能不是您想要的。


话虽如此,这是实际的做法:

$(function () {
  'use strict'

  $(document)
    .on('click', '[data-toggle="offcanvas"]', function(e) {
      $('.offcanvas-collapse').toggleClass('open'); // toggle `.open`
      e.stopPropagation(); // and stop propagation
    })
    .on('click', function() {
      $('.offcanvas-collapse').removeClass('open'); // remove `.open`
    });
})


编辑:根据评论请求,仅在单击导航栏外部时关闭画布,将第二个.on()替换为以下内容:

.on('click', function(e) {
   if (!$(e.target).closest('nav.fixed-top').is('nav')) {
     $('.offcanvas-collapse').removeClass('open'); // remove `.open`
   }
 });


它检查目标是否位于类<nav>fixed-top中。
