简单的垂直上一个和下一个按钮代码点击上下移动jQuery

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

请注意，我用.activeTab替换了.article_single_item，以获得活动的a。

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

下面的代码用于next/prev功能。我提取了函数tabChange()中的一部分公共函数。

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();
}

有关工作示例，请参阅代码段。

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();
}

        several hundred million Euros in securities and thus the UCITS fund manager was able to confirm that not more than 10% of the issuance of the Securitisation Cell Company had been purchased.</div>

    </ul>

然后你可以使用一些更好的代码，比如这样

$(function () {
    var $allTtitles = $('li.article_title');
    var titleCount = $('li.article_title').length;
    $('#title_count').html(titleCount);
    var newActiveTitleIdx = 0;
    var titleActiveIdx = 0;
    function titleListUp() {
        titleActiveIdx = $('li.article_title .active_title').index();
        $allTitles.removeClass('active_title');
        if (titleActiveIdx === 0) {
            newActiveTitleIdx = titleCount - 1;
        } else {
            newActiveTitleIdx--;
        }
        $('#art_idx').html(newActiveTitleIdx);
        $allTtitles.eq(newActiveTitleIdx).addClass('active_title');
    }
    function titleListDown() {
        titleActiveIdx = $('li.article_title .active_title').index();
        $allTitles.removeClass('active_title');
        if (titleActiveIdx == (titleCount - 1) ) {
            newActiveTitleIdx = 0;
        } else {
            newActiveTitleIdx++;
        }
        $('#art_idx').html(newActiveTitleIdx);
        $allTtitles.eq(newActiveTitleIdx).addClass('active_title');
    }
    $('#single_article_prev').on('click', function () {
        titleListUp();
    });
    $('#single_article_next').on('click', function () {
        titleListDown();
    });
});
