具有滚动功能的引导导航选项卡

Question

我在我的网站上使用 Bootstrap 导航选项卡和选项卡窗格。网站上有一些地方我想添加额外的链接来激活选项卡窗格。我的工作正常，我不知道如何让相同的链接滚动到该窗格，我认为是因为 bootstrap.js 中的这一行

    if (showEvent.isDefaultPrevented() || hideEvent.isDefaultPrevented())

我创建了一个jsfiddle 来展示我想要实现的目标。页面底部有一个按钮，可以激活第二个窗格。

我还使用 jquery easing 插件来实现平滑滚动。一旦“.page-scroll”链接激活窗格，第二次单击将正确滚动，我想我需要在同一次单击时发生这些。

谢谢，

$(function() {
    $('a.page-scroll').bind('click', function(event) {
     $('ul.nav li').removeClass('active');
     $('.tab-content .tab-pane').removeClass('active');
     $('[aria-controls="profile"]').parent().addClass('active');
        $('.tab-content #profile').addClass('active');
        var $anchor = $(this);
        $('html, body').stop().animate({
            scrollTop: $($anchor.attr('href')).offset().top
        }, 1500, 'easeInOutExpo');
        event.preventDefault();
    });
});
