javascript - 简单的垂直上一个和下一个按钮代码，点击时使用 jQuery 上下移动

Question

我用这个简单的代码创建了一个 slider

jQuery(".article_single_item .article_singlepage_title a:first").parent().parent().addClass("activeTab");
    jQuery(".accomdation_tab:first").addClass("active_tab_content");
    jQuery(".article_single_item .article_singlepage_title a").click(function(event) {
        event.preventDefault();
        $(this).parent().parent().addClass("activeTab");
        $(this).parent().parent().siblings().removeClass("activeTab"); 
        var tab = $(this).attr("href");
        $(".accomdation_tab").not(tab).css("display", "none");
        $(tab).fadeIn();
    });

使用此代码，我可以在单击时为每个项目显示以下内容。现在我还需要创建“上一个”和“下一个”按钮功能，当单击下一个时，它必须滚动或移动下一个项目等。我正在尝试使用此代码代码

jQuery('#single_article_next').click(function(){
        jQuery(".article_single_item .article_singlepage_title a").parent().parent().siblings().removeClass("activeTab"); 
        jQuery(".article_single_item .article_singlepage_title a:first").parent().parent().next().addClass("activeTab");
        jQuery(".accomdation_tab").siblings().removeClass("active_tab_content"); 
        jQuery('.accomdation_tab:first').next().addClass("active_tab_content"); 
    });
    jQuery('#single_article_prev').click(function(){
        jQuery(".article_single_item .article_singlepage_title a").parent().parent().siblings().removeClass("activeTab"); 
        jQuery(".article_single_item .article_singlepage_title a:first").parent().parent().prev().addClass("activeTab");
        jQuery(".accomdation_tab").siblings().removeClass("active_tab_content"); 
        jQuery('.accomdation_tab:first').prev().addClass("active_tab_content"); 
    });

但这不是我需要的，也不能正常工作。帮我弄清楚。

要实现 next/prev 功能，您必须使用 activeTab 并激活下一个/上一个，如下所示。

请注意，我将 .article_single_item 替换为 .activeTab 以获取事件 a。

var $activeTab = jQuery(".activeTab .article_singlepage_title a"); 

下面的代码用于下一个/上一个功能。我在函数 tabChange() 中提取了一部分常用功能。

jQuery('#single_article_next').click(function(){
    var $activeTab = jQuery(".activeTab .article_singlepage_title a"); 
    $activeTab.parent().parent().next().siblings().removeClass("activeTab"); 
    $activeTab.parent().parent().next().addClass("activeTab");

    $activeTab = jQuery(".activeTab .article_singlepage_title a");
    tabChange($activeTab) 
});
jQuery('#single_article_prev').click(function(){
    var $activeTab = jQuery(".activeTab .article_singlepage_title a"); 
    $activeTab.parent().parent().prev().siblings().removeClass("activeTab"); 
    $activeTab.parent().parent().prev().addClass("activeTab");

    $activeTab = jQuery(".activeTab .article_singlepage_title a");
    tabChange($activeTab) 
});

function tabChange($activeTab) {
    var tab = $activeTab.attr("href");
    $(".accomdation_tab").not(tab).css("display", "none");
    $(tab).fadeIn();
}

请参阅工作示例的代码片段。

jQuery(".article_single_item .article_singlepage_title a:first").parent().parent().addClass("activeTab");
jQuery(".accomdation_tab:first").addClass("active_tab_content");
jQuery(".article_single_item .article_singlepage_title a").click(function(event) {
  event.preventDefault();
  $(this).parent().parent().addClass("activeTab");
  $(this).parent().parent().siblings().removeClass("activeTab");
  tabChange($(this))
});


jQuery('#single_article_next').click(function() {
  var $activeTab = jQuery(".activeTab .article_singlepage_title a");
  $activeTab.parent().parent().next().siblings().removeClass("activeTab");
  $activeTab.parent().parent().next().addClass("activeTab");
  
  $activeTab = jQuery(".activeTab .article_singlepage_title a");
  tabChange($activeTab)
});
jQuery('#single_article_prev').click(function() {
  var $activeTab = jQuery(".activeTab .article_singlepage_title a");
  $activeTab.parent().parent().prev().siblings().removeClass("activeTab");
  $activeTab.parent().parent().prev().addClass("activeTab");

  $activeTab = jQuery(".activeTab .article_singlepage_title a");
  tabChange($activeTab)
});

function tabChange($activeTab) {

  var tab = $activeTab.attr("href");
  $(".accomdation_tab").not(tab).css("display", "none");
  $(tab).fadeIn();
}
