如何使用上一個和下一個按鈕遍歷帶有嵌套下拉菜單的Bootstrap選項卡式導航菜單？
[英]How do I traverse a Bootstrap tabbed navigation menu with nested dropdown using prev and next button?
問題描述
我有一個帶有嵌套下拉菜單的選項卡式導航的模板。 上一個和下一個按鈕應提供每個選項卡的輔助導航。 這些按鈕將一直起作用，直到需要瀏覽下拉菜單中的頁面為止。 如果使用“下一步”按鈕前進到講座，則下拉菜單中的所有頁面/講座都將顯示在按鈕下方。
我不確定在js中編寫if / else片段的最佳方法。 不知道根據我目前為止的情況還是從頭開始研究是否更好。 我需要幫助弄清楚如何使腳本在用於導航的整個列表中前進和后退。
$('.btnNext').click(function () {
$('.nav-tabs > .nav-item > .active').parent().next('li').find('a').trigger('click');
});
$('.btnPrevious').click(function () {
$('.nav-tabs > .nav-item > .active').parent().prev('li').find('a').trigger('click');
});

這是一個使用tab('show')代替trigger('click')的工作演示
$('.btnNext').click(function() { if (!$('[data-toggle="tab"].active').next('[data-toggle="tab"]').first().tab('show').length) $('[data-toggle="tab"].active').parents('li').nextAll().find('[data-toggle="tab"]').first().tab('show') }); $('.btnPrevious').click(function() { if (!$('[data-toggle="tab"].active').prev('[data-toggle="tab"]').first().tab('show').length) $('[data-toggle="tab"].active').parents('li').prevAll().find('[data-toggle="tab"]').last().tab('show') });
