javascript - 如何在 css/javascript 中创建垂直制表符？

Question

我正在使用 css 和 jquery 创建垂直选项卡元素，但我需要在页面加载时显示第一个选项卡内容。我使用以下行来显示第一个元素，但它不起作用。

$('#v-nav>div.tab-content:first-child').show();

我从下面的链接中获取垂直标签代码，请引用

请更正此代码以将第一个选项卡内容显示为默认/加载。

提前致谢。

为 div 添加了默认的 active 类，为 .active 类添加了样式 display:block; .

$(function() {
    var items = $('#v-nav>ul>li').each(function() {
        $(this).click(function() {
            //remove previous class and add it to clicked tab
            items.removeClass('current');
            $(this).addClass('current');

            //hide all content divs and show current one
            $('#v-nav>div.tab-content').hide().eq(items.index($(this))).show('fast');

            window.location.hash = $(this).attr('tab');
        });
    });

    if (location.hash) {
        showTab(location.hash);
    }
    else {
        showTab("tab1");
    }

    function showTab(tab) {
        $("#v-nav ul li:[tab*=" + tab + "]").click();
    }

    // Bind the event hashchange, using jquery-hashchange-plugin
    $(window).hashchange(function() {
        showTab(location.hash.replace("#", ""));
    })

    // Trigger the event hashchange on page load, using jquery-hashchange-plugin
    $(window).hashchange();
});
