jQuery(".element").scrollTop(0); 不起作用

Question

I have multiple tabs like this:

[tab 1] [tab 2]

--content

[tab 1] [tab 2]

HTML:

<div class="tabs">

    <ul class="tab-links">
        <li class="active"><a href="#tab1">Tab #1</a></li>
        <li><a href="#tab2">Tab #2</a></li>
    </ul>  

    <div class="tab-content">

        <div id="tab1" class="tab active">#1 content</div>

        <div id="tab2" class="tab">#2 content </div> 

    </div>

    <div class="tabs">

        <ul class="tab-links">
            <li class="active"><a href="#tab1">Tab #1</a></li>
            <li><a href="#tab2">Tab #2</a></li>
        </ul>

    </div>

</div>

As you can see there are tab list above and below the tab-content.

As long as content is long, user has to scroll-up to page when he change the tab on the tab-list-bottom.

So, I wanted to scrollTop automatically when user change the tab from below. And I added jQuery(".tab-content").scrollTop(0); into the java-script code. But somehow It doesn't respond.

Note: It works when I change jQuery(".tab-content").scrollTop(0); to jQuery(window).scrollTop(0); but this is not what I want because my content not on the top of page.

Just can't understand why it doesn't work on the first place. Has anyone figure out what is the problem?

您必须将窗口滚动到选项卡容器的顶部，您可以使用 jquery offset 函数获取.tab-content元素的偏移量，然后获取 top 属性：

jQuery(window).scrollTop(jQuery(".tab-content").offset().top);
