引导 4 在单击活动选项卡和页面上折叠导航选项卡

Question

单击导航链接时关闭活动导航选项卡，并在页面上的任何位置完成单击。

我尝试将 removeClass 从 .tab-pane 更改为所有可能的变体，即选项卡面板、导航项、导航链接和只是选项卡，但没有运气。

$(document).on('click', '.nav-link.active', function() {
  var href = $(this).attr('href').substring(1);
  //alert(href);
  $(this).removeClass('active');
  $('.tab-pane[id="' + href + '"]').removeClass('active');
});

<!-- Nav tabs -->
<ul class="nav nav-tabs" role="tablist">
  <li class="nav-item">
    <a class="nav-link" data-toggle="tab" href="#home" role="tab">Home</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" data-toggle="tab" href="#profile" role="tab">Profile</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" data-toggle="tab" href="#messages" role="tab">Messages</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" data-toggle="tab" href="#settings" role="tab">Settings</a>
  </li>
</ul>
<!-- Tab panes -->
<div class="tab-content">
  <div class="tab-pane" id="home" role="tabpanel">A</div>
  <div class="tab-pane" id="profile" role="tabpanel">B</div>
  <div class="tab-pane" id="messages" role="tabpanel">C</div>
  <div class="tab-pane" id="settings" role="tabpanel">D</div>
</div>

单击打开的选项卡上的导航链接时，输出应关闭选项卡。

Answer 1

在 BS v4 中，有一个.tab('show')方法，但没有关闭选项卡，所以你是正确的，你必须手动更新类和属性才能关闭面板。

仅当单击活动导航项触发事件时，才会触发当前事件侦听器。 这可以帮助关闭当前导航项，但通常不会对文档中的单击执行任何操作。

您将需要另一个文档级别的侦听器。 然后检查您是否单击了不属于导航的某个位置，并执行相同的代码以关闭活动选项卡

// listen for clicks to active nav
$(document).on('click', '.nav-link.active', function() {
  hideTab($(this))
});
// listen for clicks everywhere
$(document).on('click', function(e) {
  // if clicked on nav, return
  if ($(e.target).closest(".nav-tabs,.tab-content").length) {return}
  // otherwise, off clicks should close nav
  hideTab($('.nav-link.active'))
});
function hideTab($activeNav) {
  // deselect nav item
  $activeNav.removeClass('active').attr('aria-selected', "false")
  // identify tab pane & deselect
  $($activeNav.attr("href")).removeClass('active');
}

堆栈代码段中的演示

// listen for clicks to active nav
$(document).on('click', '.nav-link.active', function() {
  hideTab($(this))
});
// listen for clicks everywhere
$(document).on('click', function(e) {
  // if clicked on nav, return
  if ($(e.target).closest(".nav-tabs,.tab-content").length) {return}
  
  // otherwise, off clicks should close nav
  hideTab($('.nav-link.active'))
});
function hideTab($activeNav) {
  // deselect nav item
  $activeNav.removeClass('active').attr('aria-selected', "false")
  // identify tab pane & deselect
  $($activeNav.attr("href")).removeClass('active');
}

Answer 2

正如你所说。我认为这会对你有所帮助。

$(document).on('click', '.nav-link.active', function() {
  var href = $(this).attr('href').substring(1);
  //alert(href);
  $(this).removeClass('active');
  $('.tab-pane[id="' + href + '"]').removeClass('active');
});
$(document).mouseup(function(e) {
    var container = $("#tablist"); // target ID or class
    // if the target of the click isn't the container nor a descendant of the container
    if (!container.is(e.target) && container.has(e.target).length === 0) {
        // get Event here
        $('.active').removeClass('active');
    }
});
