如何在slideUp后执行scrollTop

Question

我在发布信息时遇到了问题。

基本上，它是横幅和标题的列表，内容div隐藏在CSS中。单击标题时，相关内容div将向下滑动。同时，任何其他打开的div都会向上滑动，这样您一次只能查看一篇文章。然后页面滚动到相关横幅div的顶部。

这是一个jsFiddle：http://jsfiddle.net/JGuilford/VzVCD/

A shadowed agony in the garden. Against the sun’s declining figures moving in the slower dusk across a paper skyline. A lone dark husbandman pursuing mule and harrow down the rainblown bottomland toward night.</p>

JQuery：

$(document).ready(function () {
    $(".entry-title-thumbnail-active").click(function () {
        $(this).closest('.site-content').find('.entry-content-thumbnail').not($(this).closest('article').find('.entry-content-thumbnail')).slideUp('slow');
        $(this).closest('article').find('.entry-content-thumbnail').slideToggle(
            'slow', 'swing', $('html,body').animate({
            scrollTop: $(this).offset().top
        }, 'slow'));
        return false;
    });
});

问题在于，如果文章已在用户单击打开的文章上方打开，则当文章关闭时，所单击的标题会向上滚动并退出视图。基本上，我无法弄清楚如何让scrollTop使用点击的.entry-title-thumbnail-active的最终位置而不是它的初始位置。要查看我的意思，请打开jsFiddle并单击Post 2，然后单击Post 3. Post 3的文章将展开，Post 2的文章将会崩溃，但窗口将尝试滚动到Post 3的初始位置的标题，而不是在Post 2崩溃后的位置。

有谁知道如何解决这个问题？

Answer 1

complete上的.slideToggle()方法是一个函数。请参阅slideToggle docs

所以它应该是：

$(".entry-title-thumbnail-active").click(function () {
    $(this).closest('.site-content').find('.entry-content-thumbnail').not($(this).closest('article').find('.entry-content-thumbnail')).slideUp('slow');

    $(this).closest('article').find('.entry-content-thumbnail').slideToggle(
        'slow', function () {
        $('html,body').animate({
            scrollTop: $(this).offset().top
        }, 'slow')
    });
    return false;
});

您也无需设置'swing'，因为它已经是默认应用easing。
